摘要
采用雷诺平均纳维—斯托克斯方程(RNAS)和标准k-着湍流模型,运用SIMPLEC算法,对某水利枢纽进行三维湍流数值模拟计算,预测了水流流动过程中产生的回流、旋涡发生的位置及形态;通过具体方案比较,提出了前池设置底坎的整流措施,有效地消除了回流与旋涡,流态显著改善,可为工程设计提供指导。
Numerical Simulation of Three-dimensional Flow is applied on inlet passage of Zhejiang boatyard pumping station, based on Navier-Stokes equations and the standard-Turbulent mode. From the computional results, the flow status, the various types of vortices are predicted. The measures of sills have been successfully applied on the project, and the solutions can be used to direct the design of the combined sluice-pump station project.
