Simulation of three-demensional unsteady flow in hydraulic pumps

Abstract:In this thesis it is shown that the flow in hydraulic pumps of the radial and mixedflow type, operating at conditions not too far from design point, can be considered as an incompressible potential flow, where the influence of viscosity is restricted to thin boundary layers, wakes and mixing areas. A three-dimensional method for unsteady flow based on this model yields good results. In order to predict the efficiency of pumps, additional models to quantify the viscous losses can be employed successfully. Thus reads the overall conclusion which can be drawn from the investigation presented in this thesis.
