Vortex Cascade Features of Turbulent Flow in Hydro-Turbine Blade Passage with Complex Geometry

A large-eddy simulation of three-dimensional turbulent flow for a hydro-turbine in the transitional process of decreasing load from rated power to no-load has been implemented by using ANSYS-Fluent in this paper. The survival space occupied by different scale flow structures for the different guide...
