Abstract

This paper is numerically presented the effect of the pre-swirl stator (or say stator) on the hydrodynamic performance of the ship propeller. The flow is oscillating into the propeller that is the same at each radius. The propeller is selected KP505 and the stator is 4 blades mounted at upstream of the propeller. With a computational fluid dynamics (CFD) method based on the general CFD by STAR-CCM+ Solver, the thrust and torque coefficients for one blade and whole blades during one cycle, the pressure at a specific on the back and face sides of the propeller and axial and cross velocities are presented and discussed.
