摘要
本文用孔隙率定义流场空间，并采用了二维Ｋ－ε紊流模式和有限体积法对ＷＣＢ型阀门阀道流场进行了模拟。通过阀门阀道的体型优化，寻求到阻力系数和过水断面较小、合理的阀道体型。
A finite volume method with staggered grid and volume porosity method is employed to simulate the flow field of valve pipes.The flow type of the calculation is in agreement with that of the experimental simulations.The optimal type of valve with less resistance has been found.
