In this study, the effects of propeller on maneuvering forces of a submerged body have been investigated by implementing body force method. The flow around a submerged body has been solved using a commercial RANS (Reynolds-averaged Navier-Stokes) solver based on finite volume method (FVM). For this purpose, a benchmark DARPA-Suboff bare hull form (AFF-1) has been chosen for the calculations. Oblique towing analyses have been carried out for two different drift angles at two different Reynolds number with and without propeller effects. The propeller-hull interaction has been modelled with an actuator disc coupled with experimental open water data based on body force method at self-propulsion points. Verification study has been carried out using Grid Convergence Index (GCI) method to determine the optimum grid number. Validation study has been done in terms of maneuvering forces and moment acting on the gravity center of submerged body with the available experimental data. The results have also been compared with those of other numerical results.
