In this paper, the hydrodynamic characteristics of a rim driven integrated thruster was numerically investigated. To consider the effect of cavitation phenomenon, multi-phase flow model and homogeneous mixture model were applied to the three dimensional incompressible RANS equations. To validate the numerical methods and the models adopted to the present study, the propeller P4381 was numerically analyzed and the numerical results and experimental one reached good agreement. The rim driven integrated thruster applied to the unmanned underwater vehicle at the water depth of 5m was numerically solved for various advance ratios. The flow field of the conventional thruster that has gap between the tip of the propeller and inner wall of the duct was also numerically solve and the results were compared to the results of the rim driven integrated thruster. As a result, it was revealed that both the rim driven integrated thruster and conventional thruster suffer from the cavitation phenomenon on the suction side of the propeller and the stator. It was also found that the difference of the thrust generated by the rim driven integrated thruster and conventional thruster is not significant whereas the difference of the torque could not be neglected. Finally, it was observed that the thrust and torque by thruster in the multi-phase flow was estimated to be smaller than those of single-phase flow.
