Abstract: It is well known, that the fluid motion in reversible hydraulic machinery elements is a complex three-dimensional problem. In this paper it is developed an explicit numerical model based on Finite Element Method and Dual Reciprocity Method for the simulation of the flow velocity and pressure distributions on blade of the Francis type reversible radial-axial hydraulic machine's runner, in the hypothesis of ideal incompressible fluid and the relative rotational motion. The proposed numerical model was applied for reversible radial–axial hydraulic machinery operating as a pump. The blade has the basic profile NP205. This profile has a quadratic equation which defines its skeleton and its thickness function is that of a NACA profile with a maximum relative thickness of five percent. The numerical results for different discharge values have finally allowed obtaining the cavitation characteristic and sensitivity curves for the reversible hydraulic machinery.
Keywords: Reversible hydraulic machines, Axial-symmetrical motion, Radial-axial profile cascades, Velocity and pressure distributions, Two-dimensional numerical model, Computer programs, Cavitation characteristic, Cavitation sensitivity curves.
