| 摘 要： | 针对某居住区附近氯气储罐连续泄漏,通过求解三维不可压缩Navier-Stokes方程、K-ε湍流模型和物质浓度方程,模拟毒气在建筑物扰动条件下的扩散过程以及浓度时空分布特征,以毒气负载为基础给出近地面毒气危害区域,探讨毒气扩散对周边居民的影响。

| Abstract: | According to continuous release of chlorine storage tank arround the residential area, the dispersion and concentration distribution characteristics of toxic gas was simulated under the building disturbance to determine dangerous regions caused from the toxic gas dispersion by using three-dimensional incompressible Navier-Stokes equation, k-ε turbulence model and substance concentration equation. Also, it discussed the influence of toxic gas dispersion on surrounding residents. |
