摘　　要：采用SST k-ω湍流模型和Schnerr-Sauer空化模型,利用滑移网格技术,建立船尾伴流影响下的吊舱推进器水动力与空泡预报的数值计算方法,分析吊舱推进器不同偏转角状态下的水动力载荷和伴流场分布,研究偏转角对桨叶表面空泡分布的影响,研究结果可为后续吊舱推进器的性能优化提供数据支撑。Based on the SST k-ωturbulence model and Schnerr-Sauer cavitation model,a numerical calculation method for the prediction of the hydrodynamic force and cavitation of poded thrusters under the influence of the aft wake was established by the sliding grid technique,and the hydrodynamic load and wake field distribution of poded thrusters under different deflection angles are analyzed.The influence of deflection angles on the cavitation distribution on the blade surface is investigated.It provides data support for the performance optimization of subsequent poded thrusters.
