摘　　要：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-o turbulence model is used to calculate the effect of duct type,hub and rim width on the hydrodynamic performance of the thruster.
