倾斜烟羽模式最大地面浓度出现位置的求解

Solution on the Distance of Maximum Ground Concentration of Inclined Plume Model

对于粒径大于15μm的尘粒子,我国环境技术标准中建议使用倾斜烟羽模式对其浓度作预测和估计。文章对该模式进行了适当的转化,利用数值分析中的迭代法和最小二乘拟合法,拟合出不同粒径的尘粒子在不同稳定度、风速条件下出现最大地面浓度的位置,同时与Gauss扩散模式中出现最大地面浓度位置的关系进行了探讨。

Inclined Plume Model has been recommended to China as environmental technology standard. In this paper, through transforming the Inclined Plume Model, by the method of interaction and minimum squares, the distance of the maximum ground concentration was fit for different diameter particles under different conditions of atmospheric stability and wind velocity. The relation between the above distance and the one resulted from Gauss Model have also been inquired.
