| Abstract: | 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. |
