摘要
本文用有限容积法直接求解三维椭圆型流动控制方程,紊流模型采用有浮力修正的K-ε模型.本文首先将该模型用于有横流情况下岸边等密度排放,以检验模型和计算程序的正确性,所得结果正确预报了排放口下游的回流区,与文献[3]的结果是一致的.然后进一步将其应用于有横流情况下的温排水、取水问题,所得结果揭示了流场的内部特征.
This paper presents three dimensional elliptical partial differential equations governing the turbulent flows and their solutions by finite volume method.The equations are based on the k-s turbulence model taking account of buoyancy force.The calculation of flow field in an open channel with side discharge is described and the calculated results by this method are in good agreement with those appeared in Reference 3.Finally,the intake discharge problem usually occurred in cooling water projects is discussed.
