In order to study the propulsion performance of podded propulsor under direct and azimuthing conditions, the hydrodynamic performance of the puller and pusher podded propulsor under different operating conditions was compared and analyzed by using the RANS method combining standard k-ε turbulence model. The thrust coefficient and torque coefficient of the puller and pusher podded propulsor under direct and azimuthing conditions were calculated and compared with the experimental results to verify the accuracy of the numerical calculation. The comparison results between the directdrive condition propulsion characteristic curve and the thrust coefficient and the torque coefficient curve of azimuthing condition indicate that the hydrodynamic performance of the podded propulsor can be accurately predicted by the numerical calculation. According to this model, the thrust and torque coefficient, and the variation law of the axial force coefficient and the lateral force coefficient of the two thrusters with angle were calculated. Results show that the proposed hydrodynamic model can accurately predict the hydrodynamic performance of the pod propulsion under different operating conditions.
