Methods for three-dimensional flows computation in hydraulic turbines

We consider the complex problem of numerically simulating a flow in the fluid passage of a hydraulic turbine that consists of a spiral casing, a cascade of stay vanes and guide apparatus vanes, a runner, and a draft tube. Methods of its solution are based on solution algorithms of the Euler equations and the Reynolds equations, as well as on tools of the geometric support of simulation used for the development of geometric models of turbine components, grids calculation in them, an interchange of flow parameters between fluid passage segments and flow visualization in them. We give the results of the flow calculations in the fluid passage of a real hydraulic turbine.
