Abstract—This paper investigates the influence of phase angle of the Propeller Boss Cap Fins (PBCF) on the hydrodynamics performance of the propulsion system including the propeller, shaft, and PBCF by Computational Fluid Dynamic (CFD) method. The rotating reference frame approach was used to simulate propeller rotation. First, the well-known Potsdam Propeller in model scale was used as an initial propeller to verify and validate the propeller performance results obtained by CFD method with experimental data and then investigate the influence of phase angle on the performance of propeller. The best phase angle for PBCF is shown and the recommendations for choosing phase angle with respect to increase propeller performance are given. The commercial solver Star CCM+ is used to solve the flow around the PBCF and the propeller.
