Analysis of the influence of rim-driven propeller appearance on hydrodynamic performance
The rim-driven thruster integrates the motor and propeller,it is a new type of ship propeller and has a high application prospect.Based on the NO.19A+Ka4-70 duct propeller,the simulation value is compared with the test value and the maximum deviation of each parameter is within 5％,and the reverse blade is constructed.Based on STAR-CCM+simula-tion software to calculate the hydrodynamic performance of the rim-driven thruster,the SST k-ω turbulence model is used to calculate the effect of duct type,hub and rim width on the hydrodynamic performance of the thruster.
