摘要

摘要: 目的为研究邮轮吊舱推进器组合式水力组件与其敞水性能间的相互映射关系，提出基于雷诺平均纳维−斯托克斯（RANS）方程的吊舱推进器水动力性能预报方法。方法以邮轮吊舱推进器缩比模型为研究对象，在深水拖曳水池中开展推进器敞水性能试验，对预报方法进行精度验证。通过仿真计算，分析吊舱推进器舱体形状、螺旋桨盘面比和桨叶数对吊舱推进器水动力性能的影响规律。结果结果表明：舱体形状对推进器敞水性能的影响较小；提高螺旋桨盘面比时，推进器的推力系数和敞水效率均先增后减，而转矩系数则在一定范围内随之增加；增加螺旋桨叶数时，推进器的推力系数、转矩系数和敞水效率均先增加后减小，而桨叶数对低进速系数下吊舱推进器敞水效率的影响较小。结论研究成果可为吊舱推进器的优化设计提供参考。

Abstract: Objective Aiming at the mapping relationship between combined hydraulic components and performance, the hydrodynamic performance prediction method of a podded propulsor for cruise ship based on Reynolds-averaged Navier-Stokes (RANS) is studied. Methods Taking a scale model of a podded propulsor as the research object, the open water performance test of the propulsor is carried out in a deepwater towing tank, and the accuracy of the prediction method is verified. The effects of pod geometry, disk ratio and blade number on the hydrodynamic performance of the podded propulsor are simulated and analyzed. Results The results show that the geometry of the pod has little effect on the open water performance of the propulsor. Increasing the disk ratio of the propeller causes the thrust coefficient and open water efficiency to first increase and then decrease, while the torque coefficient only increases within a certain range. Increasing the number of propeller blades will first increase and then decrease the open water performance of the propulsor, and the number of propeller blades has little effect on the open water efficiency of the podded propulsor under low advance coefficient. Conclusion The results of this study can provide reference value for the optimal design of cruise ship podded propulsors.
