Hydrodynamic performance test and numerical simulation of ducted propeller
In order to study the investigate between the characteristic hydrodynamic parameters and the advance coeffi-cient,this paper uses a combination of physical tests and Computational Fluid Dynamics(CFD)techniques to analyze the ef-fect of the duct on the hydrodynamic characteristics of the propeller.Firstly,the open water performance test of the ducted propeller model was carried out in the towing tank of DLUT and then the numerical simulation of the ducted propeller mod-el was carried out using the computational fluid software STAR-CCM+.In the simulation,Multi Reference Frames(MRF)method was applied to calculate the hydrodynamic performance of the ducted propeller using different turbulence models,and compared with the experimental data.It is verified that STAR-CCM+software simulation can effectively predict the hy-drodynamic performance of the ducted propeller and the accuracy of the hydrodynamic performance obtained by using SST k-ω turbulence model is higher.The results show that the ducted propeller is more suitable for ships operating at low ad-vance coefficients.
