| ○ | ○ | Article | Optimization and characterization of detector and trigger system for a KAPAE design | The Kyungpook National University Advanced Positronium Annihilation Experiment (KAPAE) aims to study ortho-positronium annihilation including invisible and visible exotic decay processes. The detector for this experiment consists of two main parts: the trigger part and the gamma-ray detection part. In this study, we focused on the development of the trigger and gamma-ray detection setup for the KAPAE detector. In the trigger setup, the suitable thickness of the plastic scintillator for positrons trigger is determined. The aerogel and nitrogen gas environment in which ortho-positronium can reduce the pick-off effect for 3-gamma annihilation is created. The gamma-ray detection part consists of 196 bismuth germanate (BGO) crystals covered with reflectors. The light yield and energy resolution uniformity of BGO crystals and the best suitable reflector for better light collection are evaluated. The source position dependency test for the BGO crystals are also examined. Single layer of polyethylene naphthalate (PEN) film plastic scintillator and aerogel with the continuous flow of nitrogen gas are found well suited for positrons trigger and annihilation environment, respectively. The light yield and its uniformity of 196 BGO crystals confirm its application for gamma-ray detection in the KAPAE detector. Moreover, the VM2000 are found the best suitable reflector due to the small thickness and good reflectivity as compared to Teflon reflector. | Jeong, Dong Woo; Khan, Arshad; Park, Hyeoung Woo; Lee, Jik; Kim, H.

| ○ | ○ | Article | Stress-activated protein kinases are involved in the replication of porcine deltacoronavirus | This study was conducted to examine the role of stress-activated protein kinases (SAPKs), including c-Jun NH2terminal kinases (JNK1/2) and p38 mitogen-activated protein kinase (MAPK), in porcine deltacoronavirus (PDCoV) infection. Results demonstrated the activation of JNK1/2 and p38 MAPK in PDCoV-infected cells, which occurred concomitant with viral biosynthesis and irrespective of cell type. Pharmacological inhibition or knockdown of either SAPK significantly attenuated PDCoV replication, whereas addition of a signaling activator augmented virus infectivity. Moreover, pharmacological inhibition of JNK1/2 or p38 MAPK activation was innocuous to viral entry but significantly detrimental to post uncoating stages of the replication cycle. Remarkably, cytokine gene expression in PDCoV-infected IPEC-J2 cells was modified by inhibiting the activation of either SAPK. Collectively, these data indicate that JNK1/2 and p38 MAPK signaling pathways contribute to viral biosynthesis and regulate immune responses, thereby favoring the replication of PDCoV. | Jeon, Ji Hyun; Lee, Changhee | Kyungpook Natl Univ, Sch Life Sci, Anim Virol Lab, BK21 FOUR KNU Creat BioRes Grp, Daegu 702701, South Korea | 57189574512; 55700560700 | changhee@knu.ac.kr; | VIROLOGY | VIROLOGY | 0042-6822 | 1089-862X | 559 | SCIE | VIROLOGY | 2021 | 3.513 | 66.2 | 0.52 | 2025-07-30 | 7 | 7 | PDCoV; SAPKs; Signal transduction; Cytokines; Viral replication | PATHWAYS CONTRIBUTE; CYTOKINE PRODUCTION; P38 MAPK; VIRUS; INFECTION; DIARRHEA; EXPRESSION; JNK; IDENTIFICATION; PREVALENCE | Cytokines; PDCoV; SAPKs; Signal transduction; Viral replication | Animals; Cell Line; Cytokines; Deltacoronavirus; Protein Kinases; Signal Transduction; Stress, Physiological; Swine; Virus Replication; cytokine; mitogen activated protein kinase 9; mitogen activated protein kinase p38; stress activated protein kinase; stress activated protein kinase 1; cytokine; protein kinase; animal cell; Article; biosynthesis; coinfection; controlled study; Deltacoronavirus; enzyme activation; gene expression; gene knockdown; immunoregulation; inflammation; IPEC-J2 cell line; JNK signaling; MAPK signaling; nonhuman; pig; porcine deltacoronavirus infection; priority journal; protein function; protein transport; signal transduction; transfected cell line; virus entry; virus infectivity; virus inhibition; virus replication; animal; cell line; genetics; immunology; metabolism; physiological stress; physiology | English | 2021 | 2021-07 | 10.1016/j.virol.2021.04.007 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | The JSNS² detector | The JSNS2 (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) experiment aims to search for oscillations involving a sterile neutrino in the eV(2) mass-splitting range. The experiment will search for the appearance of electron antineutrinos oscillated from muon antineutrinos. The electron antineutrinos are detected via the inverse beta decay process using a liquid scintillator detector. A 1MW beam of 3 GeV protons incident on a spallation neutron target produces an intense and pulsed neutrino source from pion, muon, and kaon decay at rest. The JSNS(2) detector is located 24m away from the neutrino source and began operation from June 2020. The detector contains 17 tonnes of gadolinium (Gd) loaded liquid scintillator (LS) in an acrylic vessel, as a neutrino target. It is surrounded by 31 tonnes of unloaded LS in a stainless steel tank. Optical photons produced in LS are viewed by 120 R7081 Hamamatsu 10-inch Photomultiplier Tubes (PMTs). In this paper, we describe the JSNS(2) detector design, construction, and operation. | Ajimura, S.; Botran, M.; Choi, J. H.; Choi, J. W.; Cheoun, M.

| ○ | ○ | Article | The application of diniconazole and prohydrojasmon as plant growth regulators to induce growth and tuberization of potato | The potato is a major vegetable crop around the world, and tuberous hypertrophy is a highly complex developmental process effected by various factors that play central role in potato growth. Tuber growth under hypertrophic conditions is regulated by variations in carbohydrates and endogenous Phytohormones. In the present study, we aimed to establish the basis for the enlargement of potato tubers, including changes in the chemical content of factors related to tuber formation and hypertrophy based on phy tohormonal regulation, plants height and tuber biomass and other selected attributes. Our results reveal that the application of plant growth regulators such as diniconazole (Din) and prohydrojasmon (PDJ) significantly impact on potato plants growth and yield, including that of tubers. Plants treated with Din and PDJ effectively showed stunted growth and reduced development but enhance the tuber formation and its weight. Plants treated with Din and PDJ significantly reduced the GAs and ABA accumulation and increase the sucrose level and cause significant increase in tuber development. In conclusion, a higher gibberellin content in potatoes may inhibit tuberization. Diniconazole and PDJ treatment reduced gibberellin accumulation, which in turn regulated abscisic acid content, demonstrating that the abscisic acid content mostly increased as gibberellin content decreased, and thereby promoting tuberization. | Jeong, Eun-Ju; Imran, Muhammad; Kang, Sang-Mo; Khan, Muhammad Aaqil; Lee, In-Jung | Agr Resource Management Inst, Daegu, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu, South Korea | Lee, In-Jung/GLS-0432-2022; Kang, Sang-Mo/MBG-7823-2025; Imran, Muhammad/AFL-6590-2022; Khan, Muhammad/ABB-9797-2021 | 57194549082; 58282433800; 56189696900; 57188585606; 16425830900 | ijlee@knu.ac.kr; | JOURNAL OF APPLIED BOTANY AND FOOD QUALITY | J APPL BOT FOOD QUAL | 1439-040X | 94 | SCIE | PLANT SCIENCES | 2021 | 1.483 | 66.3 | 0.67 | 2025-07-30 | 8 | 9 | ENDOGENOUS ABSCISIC-ACID; TUBER FORMATION; JASMONIC ACID; HORMONAL-REGULATION; SUCROSE; GIBBERELLIN; CELLS; BIOSYNTHESIS; INVOLVEMENT; METABOLISM | Solanum tuberosum; abscisic acid; biomass; food quality; growth; potato; sucrose; tuber | English | 2021 | 2021 | 10.5073/jabfq.2021.094.005 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | A Double-Bridge Channel Shape of a Membraneless Microfluidic Fuel Cell | A double-bridge shape is proposed as a novel flow channel cross-sectional shape of a membraneless microfluidic fuel cell, and its electrochemical performance was analyzed with a numerical model. A membraneless microfluidic fuel cell (MMFC) is a micro/nano-scale fuel cell with better economic and commercial viability with the elimination of the polymer electrolyte membrane. The numerical model involves the Navier-Stokes, Butler-Volmer, and mass transport equations. The results from the numerical model were validated with the experimental results for a single-bridge channel. The proposed MMFC with double-bridge flow channel shape performed better in comparison to the single-bridge channel shape. A parametric study for the double-bridge channel was performed using three sub-channel widths with the fixed total channel width and the bridge height. The performance of the MMFC varied most significantly with the variation in the width of the inner channel among the sub-channel widths, and the power density increased with this channel width because of the reduced width of the mixing layer in the inner channel. The bridge height significantly affected the performance, and at a bridge height at 90% of the channel height, a higher peak power density of 171%was achieved compared to the reference channel. | Oh, Ji-Hyun; Tanveer, Muhammad; Kim, Kwang-Yong | Inha Univ, Dept Mech Engn, 100 Inha Ro, Incheon 22212, South Korea; Kyungpook Natl Univ, Dept Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; Tanveer, MuhammadShahbaz/LUY-0421-2024; Kim, Kwang-Yong/AAH-2901-2020 | 57311691700; 23486949200; 7409314678 | 22201217@inha.edu;tanvir.ranjha@gmail.com;kykim@inha.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 21 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 0.29 | 2025-07-30 | 4 | 4 | membraneless microfluidic fuel cell (MMFC); double-bridge channel; mass transport losses; mixing region; numerical model | LAMINAR-FLOW; PERFORMANCE ANALYSIS; ALKALINE; METHANOL; DESIGN; FABRICATION | Double-bridge channel; Mass transport losses; Membraneless microfluidic fuel cell (MMFC); Mixing region; Numerical model | Channel flow; Microfluidics; Navier Stokes equations; Numerical models; Polyelectrolytes; Proton exchange membrane fuel cells (PEMFC); Solid electrolytes; Bridge height; Channel shape; Channel widths; Double bridge; Double-bridge channel; Mass transport loss; Membraneless; Membraneless microfluidic fuel cell; Microfluidic fuel cell; Mixing region; Mixing | English | 2021 | 2021-11 | 10.3390/en14216973 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A Stochastic Planning Model for Battery Energy Storage Systems Coupled with Utility-Scale Solar Photovoltaics | With recent technology advances and price drop, battery energy storage systems (BESSs) are considered as a promising storage technology in power systems. In this paper, a stochastic BESS planning model is introduced, which determines optimal capacity and durations of BESSs to co-locate utility-scale solar photovoltaic (PV) systems in a high-voltage power system under the uncertainties of renewable resources and electric load. The optimization model minimizing total costs aims to obtain at least 20% electric energy from renewable sources, while satisfying all the physical constraints. Furthermore, two-stage stochastic programming is applied to formulate mathematical optimization problem to find out optimal durations and capacity of BESSs. In scheduling BESSs, chronology needs to be considered to represent temporal changes of BESS states; therefore, a scenario generation method to generate random sample paths with 1-h time step is adopted to explicitly represent uncertainty and temporal changes. The proposed mathematical model is applied to a modified IEEE 300-bus system that comprises 300 electric buses and 411 transmission lines. Optimal BESS durations and capacity are compared when different numbers of scenarios are employed to see the sensitivity to the number of scenarios in the model, and "value of stochastic solution" (VSS) is calculated to verify the impacts of inclusion of stochastic parameters. The results show that the building costs and capacity of BESSs increase when the number of scenarios increases from 10 to 30. By inspecting VSSs, it is observed that an explicit representation of stochastic parameters affects the optimal value, and the impacts become larger when the larger number of scenarios are applied. | Park, Heejung | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea | 56484825400 | h.park@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 5 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 1.23 | 2025-07-30 | 14 | 17 | power system planning; stochastic optimization; utility-scale energy storage; renewable energy; solar PV; power system simulation | OPTIMIZATION | Power system planning; Power system simulation; Renewable energy; Solar PV; Stochastic optimization; Utility-scale energy storage | Battery storage; Electric batteries; Electric lines; Electric loads; Stochastic programming; Stochastic systems; Battery energy storage systems; Explicit representation; High-voltage power systems; Mathematical optimization problems; Optimization modeling; Solar photovoltaic system; Stochastic parameters; Two-stage stochastic programming; Stochastic models | English | 2021 | 2021-03 | 10.3390/en14051244 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Adaptive Power Flow Prediction Based on Machine Learning | Power flow analysis is an inevitable methodology in the planning and operation of the power grid. It has been performed for the transmission system, however, along with the penetration of the distributed energy resources, the target has been expanded to the distribution system as well. However, it is not easy to apply the conventional method to the distribution system since the essential information for the power flow analysis, say the impedance and the topology, are not available for the distribution system. To this end, this paper proposes an alternative method based on practically available parameters at the terminal nodes without the precedent information. Since the available information is different between high-voltage and low-voltage systems, we develop two various machine learning schemes. Specifically, the high-voltage model incorporates the slack node voltage, which can be practically obtained at the substation, and yields a time-invariant model. On the other hand, the low voltage model utilizes the deviation of voltages at each node for the power changes, subsequently resulting in a time-varying model. The performance of the suggested models is also verified using numerical simulations. The results are analyzed and compared with another power flow scheme for the distribution system that the authors suggested beforehand. | Park, Jingyeong; Kodaira, Daisuke; Agyeman, Kofi Afrifa; Jyung, Taeyoung; Han, Sekyung | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Tokyo Univ Sci, Dept Elect Engn, Tokyo 1628601, Japan; Korea Elect Power Corp Engn & Construct KEPCO E&C, Gimcheon 39660, South Korea; Kyungpook Natl Univ, Dept Elect Engn, Daegu 41566, South Korea | 57206479044; 56974393400; 56925217000; 22940595300; 36023785800 | jkms3815@gmail.com;daisuke.kodaira03@gmail.com;kofiagyeman@knu.ac.kr;tyjyung@kepco-enc.com;skhan@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 13 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 0.15 | 2025-07-30 | 3 | 3 | power flow; distribution network; machine learning; slack node voltage; impedance estimation | NEURAL-NETWORKS; VOLTAGE RISE; GENERATION | Distribution network; Impedance estimation; Machine learning; Power flow; Slack node voltage | Electric power transmission; Electric power transmission networks; Energy resources; Machine learning; Predictive analytics; Conventional methods; Distributed Energy Resources; Distribution systems; Low voltage systems; Power flow analysis; Time-invariant models; Time-varying models; Transmission systems; Electric load flow | English | 2021 | 2021-07 | 10.3390/en14133842 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Analysis of Driving Dynamics Considering Driving Resistances in On-Road Driving | Internal combustion engine emissions are a serious worldwide problem. To combat this, emission regulations have become stricter with the goal of reducing the proportion of transportation emissions in global air pollution. In addition, the European Commission passed the real driving emissions-light-duty vehicles (RDE-LDV) regulation that evaluates vehicle emissions by driving on real roads. The RDE test is significantly dependent on driving conditions such as traffic or drivers. Thus, the RDE regulation has the means to evaluate driving dynamics such as the vehicle speed per acceleration (v.a(pos)) and the relative positive acceleration (RPA) to determine whether the driving during these tests is normal or abnormal. However, this is not an appropriate way to assess the driving dynamics because the v.a(pos) and the RPA do not represent engine load, which is directly related to exhaust emissions. Therefore, in the present study, new driving dynamic variables are proposed. These variables use engine acceleration calculated from wheel force instead of the acceleration calculated from the vehicle speed, so they are proportional to the engine load. In addition, a variable of driving dynamics during braking is calculated using the negative wheel force. This variable can be used to improve the accuracy of the emission assessment by analyzing the braking pattern. | Song, Jingeun; Cha, Junepyo | Kyungpook Natl Univ, Sch Automot Engn, Sangju 37224, South Korea; Korea Natl Univ Transportat, Dept Automot Engn, Chungju 27469, South Korea | Song, Jingeun/MTG-2604-2025 | 56714139600; 36237962800 | sjg@knu.ac.kr;chaj@ut.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 12 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 1.09 | 2025-07-30 | 13 | 16 | on-road driving test; driving dynamics; driving resistance; vehicle speed per positive acceleration; relative positive acceleration | DUTY DIESEL VEHICLE; NOX EMISSION; SYSTEM; GRADE; IMPACT; SCR; LNT | Driving dynamics; Driving resistance; On-road driving test; Relative positive acceleration; Vehicle speed per positive acceleration | Dynamics; Engines; Light weight vehicles; Unmanned aerial vehicles (UAV); Wheels; Driving conditions; Driving dynamics; Emission regulation; Engine acceleration; European Commission; Exhaust emission; Light duty vehicles; Vehicle emission; Air pollution | English | 2021 | 2021-06 | 10.3390/en14123408 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Comprehensive Design of DC Shipboard Power Systems for Pure Electric Propulsion Ship Based on Battery Energy Storage System | With the strengthening of international environmental regulations, many studies on the integrated electric propulsion systems applicable to eco-friendly ship are being conducted. However, few studies have been performed to establish a guide line for the overall pure electric propulsion ship design. Therefore, this paper introduces the comprehensive design of DC shipboard power system for pure electric propulsion ship based on battery energy storage system (BESS). To design and configure the pure electric propulsion ship, 2 MW propulsion car ferry was assumed and adopted to be the target vessel in this paper. In order to design the overall system, a series of design processes, such as the decision of the ship operation profile, BESS capacity selection, configuration of the power conversion systems for propulsion, battery charging/discharging procedures, classification of system operation modes, and analysis of the efficiency, were considered. The proposed efficient design and analysis of the pure electric propulsion ship was qualitatively and quantitatively validated by MATLAB Simulink tool. The methodology presented in this paper can help design real ships before the system commissioning. | Kim, Ye-Rin; Kim, Jae-Myeong; Jung, Jae-Jung; Kim, So-Yeon; Choi, Jae-Hak; Lee, Hyun-Goo | Kyungpook Natl Univ, IT Coll, Sch Elect & Elect Engn, Daegu 41566, South Korea; Korea Naval Acad, Dept Elect Engn, Chang Won 51704, South Korea; Korea Electrotechnol Res Inst, Syst Control Res Ctr, Ind Applicat Res Div, Chang Won 51543, South Korea | ; Choi, Jae-Hak/D-6252-2013 | 57240497000; 57210835520; 55368433400; 55718674500; 56366533100; 15071884200 | yerin@knu.ac.kr;mms01270@knu.ac.kr;jj.jung@knu.ac.kr;ksy4rang@navy.ac.kr;choijaehak@keri.re.kr;leehg@keri.re.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 17 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 0.78 | 2025-07-30 | 11 | 13 | all-electric ship; battery energy storage system (BESS); DC shipboard power system; integrated power system (IPS); pure electric propulsion ship; shipboard microgrid | LITHIUM-ION BATTERY; MODEL; EFFICIENCY; STATE | All‐electric ship; Battery energy storage system (BESS); DC shipboard power system; Integrated power system (IPS); Pure electric propulsion ship; Shipboard microgrid | Battery storage; Design; Electric lines; Electric propulsion; Environmental regulations; Marine power plants; Secondary batteries; Ship conversion; Ships; Battery energy storage systems; Charging/discharging; Comprehensive designs; Efficient designs; Integrated electric propulsions; Power conversion systems; Shipboard power system; System operation modes; Ship propulsion | English | 2021 | 2021-09 | 10.3390/en14175264 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Dependence of N2O/NO Decomposition and Formation on Temperature and Residence Time in Thermal Reactor | Nitrogen dioxide (N2O) is a greenhouse gas that is harmful to the ozone layer and contributes to global warming. Many other nitrogen oxide emissions are controlled using the selective non-catalytic reaction (SNCR) process, but N2O reduction methods are few. To avoid future air pollution problems, N2O reduction from industrial sources is essential. In this study, a N2O decomposition and NO formation under an argon atmospheric N2O gas mixture were observed in a lab-scale SNCR system. The reaction rate and mechanism of N2O were calculated using a reaction path analyzer (CHEMKIN-PRO). The residence time of the gas mixture and the temperature in the reactor were set as experimental variables. The results confirmed that most of the N2O was converted to N-2 and NO. The change in the N2O reduction rate increased with the residence time at 1013 and 1113 K, but decreased at 1213 K due to the inverse reaction. NO concentration increased with the residence time at 1013 and 1113 K, but decreased at 1213 K owing to the conversion of NO back to N2O. | Lee, Sang Ji; Yun, Jae Geun; Lee, Han Min; Kim, Ji Yeop; Yun, Jin Han; Hong, Jung Goo | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Korea Inst Machinery & Mat, Dept Environm Machinery, Daejeon 34103, South Korea | 57221453424; 57223914011; 57223914555; 57222525959; 23092447300; 24576652200 | lsj12@knu.ac.kr;tlrksvy6218@knu.ac.kr;yg00049@knu.ac.kr;monst91@knu.ac.kr;jhyun@kimm.re.kr;jghong70@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 4 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 1.03 | 2025-07-30 | 19 | 19 | nitrous oxide (N2O); nitric oxide (NOx); argon (Ar) ambient; thermal decomposition; residence time; rate of progress; GRI-Mech 3; 0 | Argon (Ar) ambient; GRI-Mech 3.0; Nitric oxide (NOx); Nitrous oxide (N<sub>2</sub>O); Rate of progress; Residence time; Thermal decomposition | Air pollution; Catalysis; Gas mixtures; Global warming; Greenhouse gases; Nitrogen oxides; Ozone layer; Selective catalytic reduction; Industrial sources; N2O decomposition; Nitrogen dioxides; Nitrogen oxide emissions; NO concentration; Non-catalytic reactions; Pollution problems; Thermal reactors; Reduction | English | 2021 | 2021-02 | 10.3390/en14041153 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Development and Validation of Air-to-Water Heat Pump Model for Greenhouse Heating | This study proposes a building energy simulation (BES) model of an air-to-water heat pump (AWHP) system integrated with a multi-span greenhouse using the TRNSYS-18 program. The proposed BES model was validated using an experimental AWHP and a multi-span greenhouse installed in Kyungpook National University, Daegu, South Korea (latitude 35.53 degrees N, longitude 128.36 degrees E, elevation 48 m). Three AWHPs and a water storage tank were used to fulfill the heat energy requirement of the three-span greenhouse with 391.6 m(2) of floor area. The model was validated by comparing the following experimental and simulated results, namely, the internal greenhouse temperature, the heating load of the greenhouse, heat supply from the water storage tank to the greenhouse, heat pumps' output water temperature, power used by the heat pumps, coefficient of performance (COP) of the heat pump, and water storage tank temperature. The BES model's performance was evaluated by calculating the root mean square error (RMSE) and the Nash-Sutcliffe efficiency (NSE) coefficient of validation results. The overall results correlated well with the experimental and simulated results and encouraged adopting the BES model. The average calculated COP of the AWHP was 2.2 when the outside temperature was as low as -13 degrees C. The proposed model was designed simply, and detailed information of each step is provided to make it easy to use for engineers, researchers, and consultants. | Rasheed, Adnan; Na, Wook Ho; Lee, Jong Won; Kim, Hyeon Tae; Lee, Hyun Woo | Kyungpook Natl Univ, Smart Agr Innovat Ctr, Daegu 41566, South Korea; Korea Natl Coll Agr & Fisheries, Dept Hort Environm Syst, 1515 Kongjwipatjwi Ro, Jeonju Si 54874, Jeollabuk Do, South Korea; Gyeongsang Natl Univ, Dept Bioind Machinery Engn, Inst Agr & Life Sci, Jinju 660701, South Korea; Kyungpook Natl Univ, Dept Agr Engn, Daegu 702701, South Korea | ; Rasheed, Adnan/ABE-6624-2021 | 56080100700; 57211208368; 50062247400; 8662923200; 57209160180 | adnanrasheed@knu.ac.kr;wooks121@hanmail.net;leewon1@korea.kr;bioani@gnu.ac.kr;whlee@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 15 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 0.8 | 2025-07-30 | 12 | 13 | greenhouse energy modeling; renewable energy; energy-saving screen; greenhouse microclimate control | PERFORMANCE ANALYSIS; SYSTEM | Energy‐saving screen; Greenhouse energy modeling; Greenhouse microclimate control; Renewable energy | Coefficient of performance; Heat pump systems; Mean square error; Pumps; Tanks (containers); Building energy simulations; Coefficient of performances (COP); Greenhouse heating; Greenhouse temperature; Kyungpook National University; Root mean square errors; Validation results; Water storage tanks; Greenhouses | English | 2021 | 2021-08 | 10.3390/en14154714 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Digitally Patterned Mesoporous Carbon Nanostructures of Colorless Polyimide for Transparent and Flexible Micro-Supercapacitor | Here, we demonstrate the fabrication of a flexible and transparent micro-supercapacitor (MSC), using colorless polyimide (CPI) via a direct laser writing carbonization (DLWC) process. The focused laser beam directly carbonizes the CPI substrate and generates a porous carbon structure on the surface of the CPI substrate. Fluorine, which is one of the chemical compositions of CPI, can enhance the specific area and the conductivity of the carbon electrode by creating micropores in carbon structures during carbonization. Thus, the fabricated carbonized CPI-based MSC shows enhanced specific capacitance (1.20 mF at 10 mV s(-1)) and better transmittance (44.9%) compared to the conventional PI-based MSC. Additionally, the fabricated carbonized CPI-based MSC shows excellent cyclic performance with minimal reduction (<similar to 10%) in 3000 cycles and high capacitance retention under mechanical bending test conditions. Due to its high flexibility, transparency, and capacitance, we expect that carbonized CPI-based MSC can be further applied to various flexible and transparent applications. | Kim, Hyeonwoo; Hwang, Suwon; Hwang, Taeseung; In, Jung Bin; Yeo, Junyeob | Kyungpook Natl Univ, Dept Phys, Novel Appl Nano Opt Lab, 80 Daehak Ro, Daegu 41566, South Korea; Chung Ang Univ, Sch Mech Engn, Soft Energy Syst & Laser Applicat Lab, Seoul 06974, South Korea; Chung Ang Univ, Dept Intelligent Energy & Ind, Seoul 06974, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, 80 Daehak Ro, Daegu 41566, South Korea | ; Bin In, Jung/AAE-5983-2020; Yeo, Junyeob/I-1287-2013 | 57223908123; 57211075602; 57211068047; 25027363100; 58692645200 | czsa1212@knu.ac.kr;suwonnn@knu.ac.kr;ghkdxotmd@knu.ac.kr;jbin@cau.ac.kr;junyeob@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 9 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 0.65 | 2025-07-30 | 11 | 11 | laser; direct laser writing carbonization; colorless polyimide; electric double-layer capacitor; flexible and transparent micro-supercapacitor | SHELL NANOWIRE NETWORK; ACTIVATED CARBON; NITROGEN; ELECTRODES; CARBONIZATION; FABRICATION; STABILITY; FILMS | Colorless polyimide; Direct laser writing carbonization; Electric double-layer capacitor; Flexible and transparent micro-supercapacitor; Laser | Capacitance; Carbon; Carbonization; Electrodes; Laser beams; Polyimides; Porous materials; Capacitance retention; Chemical compositions; Cyclic performance; Direct laser writing; Focused laser beams; Mechanical bending; Micro supercapacitors; Specific capacitance; Supercapacitor | English | 2021 | 2021-05 | 10.3390/en14092547 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Pole and Slot Combination on the AC Joule Loss of Outer-Rotor Permanent Magnet Synchronous Motors Using a High Fill Factor Machined Coil | This paper proposes a design guideline for selecting the pole and slot combination of an outer-rotor permanent magnet synchronous motor (PMSM) using a maximum slot occupation (MSO) coil. Because the MSO coil has a large conductor area, the AC Joule loss in the conductors may be increased at high frequencies. To ensure high-efficiency for the PMSM, it is necessary to reduce the loss. Thus, it is important to select the pole- and slot- combination that has the minimum AC Joule loss. The loss is caused by skin/proximity effects and variations in the slot leakage flux. The skin effect is due to the armature winding and the variation in the slot leakage flux is due to the field flux. A method for separating the AC Joule loss due to each component using the frozen permeability method is proposed. Based on the proposed method, the effect of each cause on the loss at various pole- and slot- combinations is analyzed in this study. | Park, Soo-Hwan; Lee, Eui-Chun; Lee, Gi-Ju; Kwon, Soon-O.; Lim, Myung-Seop | Hanyang Univ, Dept Automot Engn, Seoul 04763, South Korea; Korea Inst Ind Technol, Safety Syst R&D Grp, Daegu 42994, South Korea; Kyungpook Natl Univ, Dept Elect Engn, Daegu 41566, South Korea | Park, Soo-Hwan/HTR-7747-2023 | 57188756504; 57188759648; 57212469872; 12790778500; 56421264500 | shwanp14@hanyang.ac.kr;2chun@kitech.re.kr;rrww1211@kitech.re.kr;kso1975@kitech.re.kr;myungseop@hanyang.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 11 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 0.21 | 2025-07-30 | 4 | 4 | AC Joule loss; frozen permeability; MSO coil; outer-rotor; pole and slot combination | VEHICLES | AC Joule loss; Frozen permeability; MSO coil; Outer-rotor; Pole and slot combination | Synchronous motors; Armature windings; Frozen permeabilities; High frequency HF; High-efficiency; Leakage flux; Outer rotor; Permanent Magnet Synchronous Motor; Slot combinations; Permanent magnets | English | 2021 | 2021-06 | 10.3390/en14113073 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Experimental Investigation of Air-Fuel Mixing Effects on Flame Characteristics in a Direct fired Burner | The length and pattern of air-fuel mixing plays a significant role in the uniformity, flame temperature, and emission characteristics, which can lead to a superior product quality in a non-oxidizing direct fired burner for a cold-rolled steel plate furnace. In this study, a diffusion-flame-type burner and partially-premixed-type burner were experimentally investigated to understand their effects on flame shape, flame temperature, and exhaust gas characteristics. With this aim, fuel nozzle size, nozzle hole number, fuel injection angle, and mixing distance of fuel and air were varied during the experiments. Computational fluid dynamics simulations were also performed to investigate the air-fuel mixing state for a nozzle-mixed burner and a partially-premixed burner. The results show that the flame temperature of the partially-premixed burner increases by up to 26 degrees C on average compared to that of the nozzle-mixed burner. It is also shown that the mixing distance plays an important role in the flame temperature of the partially-premixed burner. In addition, the residual oxygen concentration and volume ratio of CO/CO2 in the flue gas of the partially-premixed burner exhibit lower concentrations compared to those of the diffusion flame burner. | Lee, Cheolwoo; Kim, Insu; Hong, Junggoo | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Environm & Energy Planning Team Hyundai Steel, Dangjin City 31719, South Korea | 57223855784; 57198915574; 24576652200 | kaeru07@hyundai-steel.com;12insu@hyundai-steel.com;jghong70@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 14 | 12 | SCIE | ENERGY & FUELS | 2021 | 3.252 | 66.8 | 0.07 | 2025-07-30 | 1 | 1 | non-oxidizing direct fired; diffusion-flame-type burner; premixed flame burner; flame temperature; exhaust gas characteristics | STABILIZATION | Diffusion-flame-type burner; Exhaust gas characteristics; Flame temperature; Non-oxidizing direct fired; Premixed flame burner | Air; Cold rolled steel; Cold rolling; Computational fluid dynamics; Metal cladding; Mixing; Nozzles; Steel sheet; Computational fluid dynamics simulations; Emission characteristics; Experimental investigations; Flame characteristics; Flame temperatures; Fuel injection angle; Gas characteristics; Partially-premixed; Fuels | English | 2021 | 2021-06 | 10.3390/en14123552 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
