摘　　要：目前常用的预报螺旋桨水动力噪声方法为传统的FW-H方程,对于四极子噪声的处理需要求解复杂的体积分。渗流FW-H方法通过在虚拟渗流控制面上积分来保留四极子声源的贡献,同时降低计算负荷。采用DTMB4119螺旋桨为研究对象,对其敞水与伴流工况的水动力进行求解,并与试验值相比较,验证流场计算的准确性。随后应用渗流FW-H方法计算对应工况下的噪声性能。并对声源积分面范围和形状对声学计算的影响进行分析。渗流FW-H方法能取得较为准确的声学预测结果,且渗流FW-H方法对积分面几何形状不敏感,对积分面的范围选择较为敏感。作为可将所有声源贡献涵盖求解的噪声预报方法,渗流FW-H有着广阔的应用前景。The commonly used method for predicting propeller hydrodynamic noise is the traditional FW-H equation.For the processing of quadrupole noise,complex volume fractions need to be solved.The Porous FW-H method preserves the contribution of the quadrupole sound source by integrating on the virtual porous control surface,while reducing the computational load.This paper takes the DTMB4119 propeller as the research object,solves the hydrodynamic forces under open water and wake conditions,and compares them with experimental values to verify the accuracy of flow field calculations.Subsequently,the porous FW-H method was applied to calculate the noise performance under corresponding operating conditions.And the influence of the range and shape of the integration surface on acoustic calculations was analyzed.The porous FW-H method achieves relatively accurate prediction results,and the porous FW-H method is not sensitive to the geometric shape of the integration surface,but is more sensitive to the range of the integration surface.As a noise prediction method that can cover and solve the contributions of all sound sources,porous FW-H has broad application prospects.
