摘要
[目的]旨在探究轮缘推进器叶片构型参数对其水动力及噪声性能的影响.[方法]采用URANS/IDDES/LES湍流模型结合P-FWH方程的混合方法,在均匀流和无空化条件下对轮缘推进器的性能进行评估,并讨论其尾迹演化特点.[结果]结果显示,采用所提方法推进效率大于 55%,在 500 Hz频带内的声压级低于90 dB的设计方案,叶片螺距主要分布在1.2D～1.6D区间,叶梢弦长主要分布在0.25D～0.3D区间.[结论]研究结果可为轮缘推进器效率和噪声性能的设计提供一定支持.
Abstract
[Objective]This study aims to examine the impacts of the blade design parameters on the hydro-dynamic and hydro-acoustic performance of a rim-driven thruster.[Methods]The evaluation of the rim-driven thruster's performance is carried out using a hybrid approach wherein the URANS/IDDES/LES solver is combined with the P-FWH equations under uniform flow and non-cavitation conditions.The characteristics of its wake evolution are then discussed.[Results]For propulsion efficiency greater than 55%,the sound pres-sure level in the 500 Hz frequency band is below 90 dB in the design scheme.The blade pitch is mainly dis-tributed in the range of 1.2D to 1.6D,and the blade tip chord length is mainly distributed in the range of 0.25D to 0.3D.[Conclusion]The results of this study can provide valuable references for the design of efficiency and hydro-acoustic performance of rim-driven thrusters.
