Test and Numerical Simulation of Pressure Pulsation under the Forward and Reverse Working Conditions of a Horizontal Axial Flow Pump

Applied Sciences, 2022
In daily operation, the flow state in the runner chamber of an axial flow pump is extremely complex, and the pressure pulsation caused by the vibration of the unit and the hydraulic excitation is also extremely complex.
