Abstract

3D flow numerical modeling at the centrifugal pump inlet completed in flow rate range 0,61,3 from the BEP point. It is shown a possibility to define the incipient cavitation number in a centrifugal pump by CFD methods. Comparison with experimental data makes a conclusion that such a method can be used for improvement of cavitational quality of centrifugal pumps.
