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。
Liquid hydrogen pipelines need to be carried out at very low temperatures, require high thermal insulation, and are very dangerous in the event of a heat leak. Hydrogen generated after the heat leak will rapidly produce a gas-liquid two-phase flow, which causes great impact and harm to the devices in the filling system, resulting in accidents such as the filling system being damaged. Therefore, it is very important to simulate the liquid hydrogen injection system. The heat loss of the filter is about three times the leakage heat of the pipeline, so it is more instructive to study the heat leakage of the filter. Based on the AMEsim engineering simulation software, this paper models and simulates the liquid hydrogen injection system, and puts it into the filter fault simulation for comparison and analysis.
