Numerical Study of Effect of the Number of Propeller Blades on Cavitating Flow

Abstract:

The instability mechanism of propeller wake was investigated numerically on three propellers with different the numbers of blades. With the hybrid grid strategy and the sliding mesh, the Unsteady Navier-Stokes (N-S) and the Bubble Dynamics equations were solved to predict the axial velocity around the propellers and the vapor volume fraction in the blades surface. With the increasing of the numbers of propeller blades, the distance of the interaction decreases, and then the instability phenomena of the propellers wake are hastened.
