액체수소 저장 용기 열적 성능 해석 모델을 통한 열역학적 상태 변화 분석
강병현(Byeonghyun Kang),김민수(Min Soo Kim) 대한설비공학회 2022 대한설비공학회 학술발표대회논문집 Vol.2022 No.6
In this study, a liquid hydrogen storage tank thermal analysis program is developed considering inner/outer shell, insulation, suspension, fill/drain pipe, vent line, vaporizer and level sensor. The model is composed of tank design model, heat transfer model, two-phase hydrogen transient model. Using this model, heat transfer rate through each component is calculated and thermodynamic states variation of liquid and vapor hydrogen is analyzed. In heat transfer results, the heat transfer rate through suspension is the highest rate among the heat transfer rates through all components. In two-phase hydrogen transient model results, thermodynamic states variation of hydrogen and energy flow into hydrogen are analyzed during charging state of the tank. Temperature and vapor pressure of hydrogen vapor vibrates because of compression work of liquid hydrogen, heat flow from the environment and venting process.
