The SST k-ω model is used to simulate the open water performance of the ducted propeller, and the hydrodynamic performance is compared with the experimental results. The SST k-ω model is validated to effectively predict the hydrodynamic performance of ducted propellers. Based on the analysis of the optimization of the ducted propeller, guide blades are installed in front of the blades to improve the performance of the ducted propellers. The performance of the ducted propellers on the ducted propellers is analyzed, and the influence laws are studied to provide a theoretical basis for the subsequent improvement of the ducted propellers.
