NUMERICAL VALUE SIMULATION OF INNER FLOWN CHANNEL OF THE OPEN CENTRIFUGAL IMPELLER

Abstract

Abstract: The clumpy gridding technic, Reynolds average N-S equation and application S-A turbulence model are adopted to do the numerical simulation for inner flow field of the open straight-leave high-speed centrifugal pump impeller, The open high-speed centrifugal pump is experimentation studed. After compared the result of the numerical value simulation with that of the experimentation. The numerical simulation can preferably simulate the inner flow field of the centrifugal pump impeller, is got. The reasons inflecting the inner flow field and the outer characteristic of the centrifugal pump impeller, are summarized. This study brought valuable references in optimizing designing and in improving the efficiency of pumps.

Key words: Centrifugal pump, Experiment study, Open impeller Numerical simulation, Dislocation distribution, Ductile to brittle transition, Grain boundary, Graphite nodules, Impact absorbed energy, Ferrite cast iron
