Abstract; The numerical simulation strategies of azimuth thruster under multiple turning-angle working conditions are re searched and designed, and the hydrodynamic performance of which is numerically simulated using CFD software Fluent., In or-der to verify the validity of the above-mentioned numerical simulation strategies, model test of azimuth thruster under multiple turning-angle working conditions is conducted at the towing tank of SSSRI. It is through comparison of model test results with that of numerical simulation that the validity of the numerical simulation strategies are verified, Based on model test and numer ical simulation results, the hydrodynamic performance of azimuth thruster under multiple turning-angle working conditions and at different velocities is analyzed, and the influence of turning angle and velocity on hydrodynamic performance of azimuth thruster is summarized.
Key words: azimuth thruster; turning-angle; hydrodynamic performance; numerical simulation; model test
