摘　　要：潜艇螺旋桨工作在非均匀的潜艇尾流中,潜艇尾流的不均匀性直接与螺旋桨的旋转噪声相关。在分析潜艇主附体结合部马蹄涡对潜艇尾流不均匀性影响的基础上,设计了消涡整流片以削弱马蹄涡强度。结合数值计算方法计算了消涡整流片作用下的潜艇模型的流场和螺旋桨的旋转噪声。结果表明:消涡整流片可以较好地降低潜艇尾流的周向不均匀性、控制潜艇螺旋桨非定常力的变化幅度,并抑制螺旋桨的旋转噪声。在消涡整流片的作用下,螺旋桨所对应的1阶叶频声源级噪声值下降约4dB。The submarine wake at the propeller disc is the inflow of the submarine propeller;the circumferential uniformity of the wake has directly influence on the rotating noise of submarine propeller.The effect of the horseshoe vortex generated at the body-appendage junctions on the submarine wake is illustrated,and the vortex control baffler is designed to weaken the horseshoe vortex.Its effect on the submarine flow characteristic and propeller rotating noise is numerically simulated.Results show that the vortex control baffler could decrease the circumferential non-uniformity of the submarine wake,reduce the variation amplitude of the blade unsteady force,and control the propeller rotating noise.The sound pressure level of the submarine propeller is decreased about 4dB responding to the one-order blade frequency.
