摘要
通过水气二相流(VOF)方法的标准k-ε双方程紊流数值模型对旋流式竖井泄洪洞的水面线、压力、流速、紊动能及紊动耗散率等重要的水力要素进行数值模拟并通过试验对计算结果进行比较分析,结果表明:计算值与实际测量值吻合比较好,验证了VOF方法的标准k-ε双方程对旋流式竖井泄洪洞水力要素模拟的可行性。
In this paper, the standard k-ε two-equation model for turbulent flow with VOF method is used to simulate the important hydraulic factors such as water surface profile,pressure and the velocity of the flow near the wall in the the silovortex spillway,the turbulent kinetic energy and the turbulent dissipation rate of energyh disspation.Experimental measure is mentioned to compoare with the numerical simulation and the results indicate that there is no striking difference between the numerical simulation and experimental measure Namely,it is feasible to use the method to simulate the hydraulic factors in the the silo vortex spillway.
