摘　　要：采用了基于两相流理论的三维相间界面计算模型模拟湖泊风生流,并采用交错网格的有限体积法求解。该模型应用于昆明市滇池的风生流模拟,实际计算表明该模型算法程序简单,计算结果合理,能较真实的反映湖泊风生流的流态特征。Wind-driven water current in lake was modelled with 3D gas-liquid interface prediction model based on two-phase flow theory. The Finite Volume Method (FVM) of the Araka-wa c-grid was employed to obtain the numerical solution. The model was used in simulation of wind-driven water current of Dianchi Lake, Kunming, and results showed that the 3-D model can better describe structural characteristic of wind-driven water current of the Lake with simple computer program and reasonable calculated results.
