摘要
以氯气为例,研究变截面重气卧罐的泄漏和扩散。采用复合求积数值计算方法和高斯模型,准确计算了氯气卧罐泄漏及扩散的过程,同时运用MATLAB软件模拟了氯气泄漏扩散过程,得到了不同风速下的扩散区域。最后根据模拟的结果,运用statistical软件拟合出风速与扩散下方向及垂直方向扩散距离的关系,为有风情况下重气泄漏的安全疏散提供合理的安全距离,进一步促进应急救援工作的实施。
Taking chlorine for example,the article analyzed the leakage and spread of cross-section heavy gas tank.Adopted compound integral numerical calculation method and Gauss model,the leaking and spreading process of chlorine tank are accurately calculated.And at the same time,using MATLAB software,the leaking and spreading process of chlorine are simulated,and diffusion area at the different wind speed is obtained.Finally,according to the results of the simulation,using statistical software,the paper fits out the relationship of wind speed,spreading direction and vertical spreading distance,providing referenced safety exit distance of heavy gas leakage and further promoting the implementation of the emergency rescue.
