NUMERICAL PREDICTION OF BOW THRUSTER PERFORMANCE USING RANSE METHOD

Abstract

The paper presents the numerical simulation results of hydrodynamic characteristics of bow thruster (thrust coefficient K_T, torque coefficient K_Q) in different pitch angles using RANSE method. Sliding mesh method is used to simulate a rotating propeller. The grid independence study on the simulation results is investigated. To ensure that the calculation findings are reliable, the numerical results are compared to the experiment results. Besides, the flow fields are performed to study the effect of flow around the bow thruster and the hull. It is explained for the additional thrust to the hull in the results.
