Abstract

In this study, numerical simulations on the noise of the underwater marine propeller for different pressures, skew angles, and performance conditions are investigated. The study has been carried out for the prediction of cavity and noise cavitation characteristics of the propeller. The blade sheet cavitation created by an underwater propeller is then evaluated using numerical analysis. The cavitation and cavity around marine propellers were predicted using MRF (Multiple Reference Frame) techniques. The simulation uses the Reynolds Averaged Navier-Stokes (RANS) formulation with the turbulence model k-ω Shear Stress Transport and the Fast Fourier Transform. The FW-H equation is used to measure far-field radiation under various operating conditions. The simulation is carried out to present that the pressure and skew propeller angles have an effect on the form and area of the cavity, as well as cavitation noise. The noise characteristics at various positions of hydrophones and speeds of the marine propeller are presented. The 3D model of B-series marine propeller with D=250 mm, Z=4, P/D= 1.0, AE/AO=0.55, skew angles of 16, 35, 53, and 72 degrees at advance coefficient, J=0.221, is used for the simulation

船用斜螺旋桨空化噪声的数值研究

在本研究中，对不同压力、斜角和性能条件下水下螺旋桨的噪声进行了数值模拟。对螺旋桨空腔和噪声空化特性进行了预测研究。然后使用数值分析来评估水下螺旋桨产生的叶片空化。利用MRF（Multiple Reference Frame，多参考系）技术对船舶螺旋桨周围的空化和空腔进行了预测。模拟使用雷诺平均纳维-斯托克斯（RANS）公式和湍流模型k-ω剪切应力输运和快速傅立叶变换。FW-H方程用于测量各种操作条件下的远场辐射。仿真表明，压力和斜桨角对空腔的形状和面积以及空化噪声都有影响。介绍了水听器在不同位置和船用螺旋桨转速下的噪声特性。采用D=250mm、Z=4、P/D=1.0、AE/AO=0.55、斜交角分别为16、35、53和72度的B系列船用螺旋桨三维模型，在推进系数J=0.221下进行仿真
