Simulation of hydrodynamic performance of shaftless rim-driven thruster based on STAR-CCM+

无轴轮缘推进器(RDT)是一种振动噪声低、推进效率高的集成式电机推进器,具有广阔的应用前景,对其开展水动力研究有重要意义。本文基于STAR-CCM+,采用Realizablek k-ε模型完成RDT水动力性能的仿真计算,并将计算结果分别与RDT模型的实验结果和常规导管桨的敞水性能CFD值进行对比分析。

Shaftless rim-driven thruster(RDT)is an integrated motor thruster with low vibration and low noise and high propulsion efficiency.which has broad application prospects and is of great significance for its hydrodynamic research.Based on the STAR-CCM+,the numerical calculation of the hydrodynamic performance of RDT is completed by using Realizablek k-c model,and the calculation results are compared with the experimental results of the RDT model and the open water performance of conventional ducted propeller.
