Calculation definition of centrifugal pumps cavitational characteristics

Results of calculation research the centrifugal pump cavitational characteristics with use of program complex ANSYS CFX 12 on the basis of flow diphasic model and the approach of hydromechanical engineering department of StPSPU, based on the analysis of pressure distributions epures on blades of driving wheels at non-cavitational flow are presented. Both approaches have yielded qualitatively close results and the good coordination with experiment. The second approach demands considerably smaller expenses of time for carrying out the calculations.
