| Abstract: | The concentration field distributions of the elevated point sources is calculated using a numerical calculation method. The numerical simulation models for the three-dimensional wind field and concentration field are set up through solving the equations of atmospheric dynamic-thermodynamics and diffusion equation for a complicated terrain, which are verified by combining the practice of Yunnan Kaiyuan Electric Power Plant. It is proved that this method may become a practical one for solving the atmospheric pollution diffusion in the complicated terrains. |
