Spatiotemporal modal dynamics and nonlinear characteristics of pressure fluctuations in a centrifugal pump under off-design operation
Off-design operation reorganizes centrifugal-pump pressure pulsations through interaction between the rotating impeller discharge and the stationary volute. To clarify how the non-uniform impeller-outlet pressure field is concentrated and modulated in the volute, unsteady computational fluid dynamics was performed at 0...
