摘要

Hydrogen fuel cell electric vehicles (HFCV) have been paid great attention due to zero carbon emission. In order to enable HFCV to travel a longer distance, requirements on its pressure reducing system are put forward. In this study, a Computational Fluid Dynamics (CFD) model was proposed to predict the hydrogen flow through a perforated plate in the pressure reducing system. Peng–Robinson (PR) real gas Equation of State (EOS) was used to describe the thermodynamic properties of hydrogen to obtain an accurate prediction. A high pressure air expansion experiment was simulated using the CFD model as validation. In addition, the effects of perforated plate structures on the hydrogen flow were studied. It was found that the size of the orifice affects the hydrogen flow significantly. This study may provide a feasible methodology involved with high pressure reducing system for HFCV.
