A numerical method based on potential flow theory is developed to calculate the performance and flow field of a propeller with boss cap fins. The vortex lattice method is applied to the calculation of both propeller and boss cap fins. The boss is calculated by using a panel method. A trailing vortex wake model is proposed for a propeller with boss cap fins, in which the axial variation of trailing vortex pitch is calculated by a wake alignment procedure. The slipstream velocity distributions and hydrodynamic forces are calculated for a propeller with and without boss cap fins. The numerical results show fairly good agreement with experimental data in slipstream velocity distributions. But it is necessary to treat the flow around boss cap fins more strictly so that the calculation of hydrodynamic forces acting on propeller blades, boss cap fins, and propeller boss including the boss cap can be improved.
