During the liquid hydrogen filling process,the vibration of pipeline will affect the safety and efficiency. In order to study the influence of cryogenic pipeline vibration on the liquid hydrogen filling process and make the filling process fast and safe,a three-dimensional model of liquid hydrogen flowing in a pipeline was established. In this paper,the volume of fluid function( VOF) coupled with Level-Set method was employed to simulate and analyze the heat transfer and flow characteristics of liquid-hydro...
