摘要
概述了水轮机内部流动计算近几十年的发展历史与研究现状,介绍了水轮机内部三维流动计算的控制方程及其解法以及常用商业软件,总结了湍流的数值计算方法,重点讨论了湍流模型理论,并指出水轮机内部湍流计算正朝着全三维、小尺度、瞬时化处理发展。
This paper summarizes the development and status of numerical simulation for turbulent flow in hydraulic turbine, and describes on three- dimensional flow calculation equation as well as the commonly commercial software. It introduces the numerical method for turbulence, discusses the theory of turbulence model, and points out that the simulation is moving for the entire three- dimensional, small - scale and instantaneous calculation.
