홈페이지논문 초록 (Abstract)
This study develops a mathematical model that predicts the dynamics of the temperature and pressure distributions, and phase changes in a Liquefied Natural Gas (LNG) fuel tank during the fuelling process. Using the Computational Fluid Dynamics (CFD) simulation results, it is shown that the LNG tank exhibits a vertical temperature distribution over the vapor phase during fuelling. Reflecting this insight from the CFD simulation, the developed model is a one-dimensional model for the vapor phase and a well-mixed model for the liquid phase. The developed model uses a moving boundary method to track the vapor–liquid interphase, reflecting the changing volume in a fixed discretised domain. Therefore, conservation equations are re-derived in order to account for the volume of the vapor phase that changes with the LNG injection. In addition, the model includes the interphase mass transfer, which reflects the phase change due to the pressure drop and heat transfer. The developed mathematical model was simulated using gPROMS™ and the results were validated with the CFD results.
