摘　　要：为了解HCRSP推进器操舵工况的空泡性能,首先对E779A桨空泡性能进行了数值模拟,验证了算法的有效性,其次对混合式CRP推进器空泡性能进行了数值模拟。发现HCRSP推进器在操舵工况下前桨空泡基本不受后桨、吊舱影响,后桨空泡形态受前桨、吊舱和偏转角影响,空泡面积随周向角脉动变化。网格划分采用结构化重叠网格,提高了吊舱偏转后的网格质量和网格生成效率。本文的研究结果为HCRSP推进器的设计提供了参考。To better understand the cavitation performance of HCRSP under steering conditions,primarily the E779A propeller cavitation was simulated as to validate the simulation method,then the numerical simulation of HCRSP cavitation performance was carried out.It was found that the cavitation of fore propeller is hardly affected by the aft propeller and pod,while the cavitation of the aft propeller is affected by the fore propeller,pod,and steering angles.The cavitation area fluctuates with the circumferential angle.Overset grid assembly tools were used to generate high-quality and high-efficiency overset meshes,especially for the steered pod.This paper provides references for the design of an HCRSP with better cavitation performance.
