侧向来流对水下航行器推进器流噪声影响的数值研究
Numerical study on the influence of side-on inflow on the flow-induced noise of underwater vehicle thrusters
摘要
Abstract
During practical operations,underwater vehicles may encounter side-on inflow,which substantially al-ters the flow-induced noise characteristics of the propeller.To investigate the influence mechanism of side-on in-flow on the flow-induced noise of underwater vehicle propellers,the E1619 seven-bladed propeller is taken as the research object,and the Detached Eddy Simulation turbulence model is combined with the Ffowcs Williams-Hawkings equation for flow-noise prediction.The effects of different side-on inflow angles(0°,60°,90°)on the flow field and acoustic field under various propeller rotation speeds are systematically analyzed.Results indicate that side-on inflow directly reconfigures the noise source types and spatial distribution by disrupting flow field sym-metry and modulating the evolution patterns of vortex structures,ultimately influencing the flow-induced noise.These findings provide theoretical support for the low-noise design of underwater propellers.关键词
