Abstract: In order to study the influence of steering conditions to hybrid CRP podded propulsor, the calculation of the NACA0012 open-water rudder's lift coefficient was carried out by applying the RANS method combined with the SST k-ω turbulence model, and the near wall mesh arrangement and near wall treatment method applied in numerical calculation were selected through comparisons between the experimental results and the calculation results. The hydrodynamic performance of a podded propulsor was predicted on the basis of the above, and the calculation results showed a good agreement with the experimental results. The object of the research was a hybrid CRP podded propulsor, and its hydrodynamic performance in steering conditions was predicted by applying the numerical method above. Conclusions were drawn on the relationship between hydrodynamic performance parameters and steering angle, i.e. larger magnitudes of the after propeller thrust, pod horizontal force and steering moment will be acquired at larger steering angles, and the fore propeller thrust is basically as invariant as the pod steering. The internal reasons were also analyzed. Research shows that the propeller has good maneuverability, and will have wide application prospect.
