摘要:对氢气小孔泄露问题进行了理论分析,并利用Simulink和Fluent软件分别对氢气小孔泄露问题进行仿真。结果表明:温度对氢气小孔泄露的影响不显著,而氢气压力和储氢空间对氢气小孔泄漏的影响较大;主动通风可抑制车内氢气泄露;密闭空间内氢气泄露具有泄露点聚集特性,并且受重力影响氢气在高处聚集。



Abstract:A theoretical analysis of hydrogen leakage through small holes was carried out, and the simulation of hydrogen leakage through small holes was conducted with Simulink and Fluent respectively. It is shown that the temperature has no significant effect on the hydrogen leakage, while the hydrogen pressure and the size of hydrogen storage space have a greater effect on hydrogen leakage process. Active ventilation is helpful to reduce hydrogen leakage inside the car. In addition, the hydrogen leakage in the confined space has the characteristics of leakage point accumulation, and the hydrogen accumulates at high places because of gravity.
