Presents the results of current studies of the spatial flow of viscous incompressible fluid flow in Kaplan turbine, designed by the pressure of 20 m. The flow-through part includes a spiral case, guide vanes, runner and draft tube. Modeling of flow was carried out on the basis of the numerical integration of the Reynolds equations with a two-parameter model of turbulence Menter (SST) using software of complex FlowER-U. The analysis of flow patterns in all parts of the flow part.

Key words: turbine, running part, numerical simulations, the viscous flow.
