| 摘 要： | 本文对山地和丘陵地区中烟羽浓度扩散分布的计算提出一种方法,该方法引用浓度方程的分析解,通过对山地绕流数值计算速度势和流函数,可较简易地求得烟羽浓度分布。作为算例,文中对中条山某工厂烟囟排放的SO2,预测了它在各种风速时被输运扩敢的浓度分布。

| Abstract: | A numerical algorithm to compute the plume pollutant concentrations near mountain areas was developed, based on the analytical solution of the equation of the pollutant concentrations. After calculating the velocity potential and stream function of the potential flow external to the wake, we found the distribution of the plume pollution concentrations easily without studying the details of the flow. With this method, the numerical results were presented and the concentration distribution of SO2 from a smoke source was predicted. |
