Performance Prediction of Cavitating Water-Jet Propulsors Using a Viscous/Inviscid Interactive Method

摘要

The authors present a viscous/inviscid interactive method to predict the viscous flow inside water-jet pumps, including the effects of sheet cavitation on the rotor blades. The circumferentially averaged interaction between the rotor and the stator is accounted for in an iterative manner. The method is applied in the case of an actual water-jet pump and comparisons of the predicted and the measured rotor torque are presented.
