轮缘推进器将电机与螺旋桨一体化设计，具有较高的应用前景。本文以NO.19A+Ka4-70导管螺旋桨为基础，将仿真值与试验值进行比较，各项参数的最大偏差均在5%以内，吻合较好，并构造反厚度规律的桨叶。基于STAR-CCM+仿真软件对轮缘推进器进行水动力性能的数值计算，采用SST k-ω湍流模型进行计算，对比分析轮缘推进器的外形、导管种类、桨毂、轮缘宽度对于推进器水动力性能的影响。
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+ simulation 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.
