液氢加注系统中过滤器漏热故障仿真与分析

液氢管道输送需要在极低温度下进行,需要较高的保温措施,而且出现漏热故障的时候将十分危险。发生漏热后的液氢会迅速产生气液两相流,其对加注系统中的器件造成很大的冲击与危害,造成加注系统损坏等事故。因此,对液氢加注系统进行仿真研究有着重要的作用。而过滤器漏热的影响大约是管道漏热的三倍,所以研究过滤器漏热更具有防范风险的指导意义。本文依据AMEsim工程仿真软件,对液氢加注系统进行建模与仿真,并置入过滤器故障仿真进行对比与分析。

Hot-leakage fault simulation and analysis of filter in liquid hydrogen filling system

Hydrogen Pipeline needs to run at very low temperatures,requiring a higher insulation measures.When the heat leakage occurs the failure it will be very dangerous.Leaking heat of liquid hydrogen occurs and rapidly produces gas-liquid two-phase flow,its filling system components will cause great impact and harm,the filling system will be damaged.Therefore,the simulation of liquid hydrogen filling system plays an important role.The heat-leakage of the filter is about three times than the pipe heat leakage,so to study the heat leak of the filter to prevent the risk is more significance.In this article using AMEsim engineering simulation software,A liquid-hydrogen filling system was modelled and simulated.The comparison and analysis of the filling system simulation with the filter fault simulation were made.
