摘　　要：针对动力定位船舶带有数量众多推进器的特点,展开动力定位船桨间干扰的研究。采用基于RANS方程和RNG k ε湍流模型,结合滑移网格处理旋转流动的数值计算方法,首先展开螺旋桨敞水特性的计算,然后采用控制变量的研究方法先后研究了不同间距,不同方位角和不同进速下的螺旋桨推力减额。并与前人的试验结果进行比较,验证了计算的有效性。相关分析结果为推进器布置和动力定位船推力分配算法的研究提供了基础和依据,具有良好的工程应用价值。Aiming at the characteristics of dynamic positioning vessel with a large number of propellers, the research on the interference between propellers of dynamic positioning vessel is carried out. Based on the RANS equation and RNG k-ε turbulence model, a numerical method for rotating flow is presented by using a sliding mesh. Firstly, the open water characteristic of propeller is calculated, and then the thrust reduction under different spacing, azimuth and advance speed is studied successively by using the method of control variables. The validity of the calculation is verified by comparing with the experimental results of predecessors. Relevant computational research provides a basis for thrust allocation algorithm and has good engineering application value.
