【Abstract】 [Purpose] To improve the performance of ducted propellers, [Method] based on the Reynolds averaged Navier Stokes(RANS) method, the effect of adding front or rear stators on the performance of accelerated ducted propellers is explored. Computational fluid dynamics(CFD) method is used, combined with pool experiments, to analyze the open water performance of ducted propellers with stators and verify the accuracy and effectiveness of the method. The open water performance of ducted propellers with different profile camber, installation angle, profile thickness, and number of stators is predicted, and the influence of parameter changes on hydrodynamic performance is analyzed. [Results] The results show that when using the optimal pre stator guide vane propeller, the net thrust under dredging conditions increased by 15.13% compared to the original propeller, the speed under free navigation conditions increased by 5.03%, and the propulsion efficiency also increased by 2.7%. When using a rear stator guide vane propeller, the net thrust under dredging conditions increased by 7.4% compared to the original propeller, the speed under free navigation conditions increased by 2.3%, and the propulsion efficiency also increased by 2.13%. [Conclusion] The research results can provide some references for the design and optimization of ducted propellers.更多还原
