Numerical simulation of complex flow structures and pressure fluctuation at rotating stall conditions within a centrifugal pump

Abstract Rotating stall contributes to global oscillation vibration problems, accompanied by noise and possible turbomachinery damage. This study with special emphasis on the vaned diffuser investigates the unsteady pressure interaction with the stall within the pump. A low specific speed centrifuga...
