复杂地形污染物扩散模式

The Complex Terrain Diffusion Model

目的 筛选出较好的复杂地形烟羽扩散模式 .方法 模式比较和实验验证 .结果与结论 通过不同模式比较和风洞模型实验验证 ,筛选出 CTDM模式是一个比较先进的复杂地形扩散模式 ,可以在重大建设项目中对大气扩散的计算结果进行验证 ,作为检验模式使用 。

Aim: To select a better smoke plume diffusion model over comple terrain. Methods: Model comparison and test by experiment. Results and Conclusions: By model comparison and experimental test in wind tunnel, it is decided that CTDM is a more advanced diffusion model over complex terrain. The calculation result of atmosphere diffusion can be used in important construction projects. As a testing model, it has its practical value.
