在水库大水体研究中引入Ｋε模式，将水动力方程与水温水质方程耦合建模，合理考虑了水流运动与水温水质分布的相互影响．水质模型中描述了污染物运动变化的分子扩散、湍流扩散及弥散．模型解法上采用具有自动迎风效应的混合有限分析五点格式．在红枫湖垂直剖面二维ＣＯＤ分布研究中取得良好效果．
Kε model was introduced in the study of large reservoirs of reservoirs, coupled with the modeling of water-temperature and water-temperature equations, the mutual influence of water-flow motion and water temperature distribution was reasonedly considered. The water quality model describes the molecular diffusion, turbulent diffusion and dispersion of pollutant movement. The model solution uses a hybrid finite five-point format with an automatic windward effect. In the vertical profile of Hongfeng Lake two-dimensional distribution of COD achieved good results.
