| 摘 要： | 以氢气在道路运输过程中发生的泄漏扩散事故为研究对象,在传统高斯点源模型基础上考虑车辆运行的影响,从瞬时泄漏和连续泄漏两个方面模拟道路运输氢气发生泄漏后的扩散过程。通过在实例研究中使用MATLAB对扩散过程进行仿真模拟,得到氢气的浓度分布范围、分布规律以及扩散规律,对于事故现场的应急处置有着重要的指导意义。

| Abstract: | The leakage and diffusion accidents of hydrogen in road transportation are studied. Based on the traditional Gaussian point source model and considering the influence of vehicle operation, the diffusion process of hydrogen in road transportation is simulated from two aspects of instantaneous leakage and continuous leakage. In case study, MATLAB is applied to simulate the diffusion process and the distribution area and distribution and diffusion laws of hydrogen concentration are obtained. It has important significance in guiding the emergency at the scene of the accident. |
