Abstract

The paper presents the results of numerical research of three-dimensional viscous fluid flow in the spiral casing of a reversible hydraulic machine performed using the Reynolds averaged Navier-Stokes equations and k-e turbulent model implemented in the software tool FlowVision. A two spiral casings, expected on laws Vu×r=const and Vu=const, execute calculations. The analysis of structure of fluid and feature of flow is executed in two spiral casings
