Numerical Study of the Effect of Propellers Skew on Cavitation Performance

Abstract:

The effect of propeller skew on cavitation distribution, thrust and the torque is studied numerically. 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 vapor volume fraction around ships propellers blades. The numerical predictions of the sheet and the tip vortex cavitation of the propeller E779A are in agreement with the results in other literature in general. For propeller models DTMB, the proper increase of the propeller skew angle may enhance the hydrodynamic performance.
