k~ε紊流数学模型应用于河道冲刷模拟初探
Application of k~εTurbulence Mathematical Model in Simulation of Riverbed Scouring
【摘要】 对三维贴体坐标k~ε紊流数学模型应用于泄洪洞出口下游河道冲刷模拟进行了初步探讨 ,计算成果可以定性分析下游河道冲刷程度 ,有助于挑坎体型和下游河道防护的合理设计
【Abstract】 A new consideration to simulate the riverbed scouring caused by deflecting jet is introduced by use of 3 d k~ε turbulence mathematical model with the body fitted coordinate.Thus the riverbed scouring degree could be qualitatively analyzed,which helps for reasonable design of bucket type of spillway tunnel outlet and safety measure of downstream river channel.
