摘要
利用开源程序包Open FOAM对激波管内的高压氢气泄漏自燃现象进行数值模拟,通过与实验数据的比较证明模拟结果的正确性,并对比分析H2在不同工况、结构条件下的泄漏自燃特性。研究结果表明:H2的初始压力和初始温度,下游管道的直径和长度等条件均会影响管内激波的产生与传播,从而对高压氢气泄漏自燃现象产生重要的影响。
The open sourced program OpenFOAM is used to simulate the spontaneous ignition process of pressurized hydrogen release in shock-tubes. By comparing different initial pressures and temperatures of hydrogen and different diameters and lengths of the downstream tubes, the numerical study reveals that all those aspects mentioned above are essential to leading the spontaneous ignition in the shock-tubes.
