Assessment of acoustic and pulsation characteristics of centrifugal pumps

Assessment of acoustic and pulsation characteristics of centrifugal pumps

Numerical investigations of unsteady viscous flow in centrifugal pumps were conducted in this paper. Verification of numerical approach was done. Hydraulic components of the pump were modernized with the purpose to improve their acoustic characteristics. Modernization was held on the base of isotrop...
