轮缘推进器叶片构型参数和水下辐射噪声的关联性
Correlation between blade parameters and underwater radiated noise of rim-driven thruster
摘要
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.关键词
