| 摘 要： | 基于FULUENT软件的物质传输与反应模块,建立了燃料车内氢气泄漏扩散的数值计算模型.应用模型对储气瓶不同位置的泄漏扩散进行了数值计算,得到了氢气在车内泄漏扩散后的危险区域分布情况.结果表明:氢气瓶上方挡板位置是氢气泄漏扩散后的高浓度区域,泄漏后的氢气在该处容易发生积聚.研究结论可以为车内预警用氢气监测传感器的放置以及氢燃料车的安全设计提供参考. |

| Abstract: | A numerical model for dispersion of hydrogen in hydrogen powered automobiles was established basing on species transport and reaction module of FLUENT. And corresponding numerical simulations were done in order to analysis the dispersion of hydrogen due to leakage from different position of the storage cylinder. Also,the distribution of the hazard region due to hydrogen dispersion was obtained. The results show that the baffle above the cylinder can accumulate the hydrogen. Therefore,the high concentration ... |
