Analysis of Centrifugal Pump in Diffuser Vane By Using CFD.

Flow analysis in centrifugal pumps has long been an intensive subject of research. Computational Fluid art technique for fluid flow analysis. It was found that non-uniformities design conditions which result in the decrease in efficiency different radial gaps. The operating characteristic curves predicted by the numerical simulation were compared with the are found in good agreement. The test case consists of an enshrouded centrifugal impeller with seven blades and a radial vane diffuser with 7 vanes. A large number of measurements are available in g this case ideal for validating numerical methods. Results of steady and uns
