中文摘要:
      水下对转螺旋桨流致辐射噪声的预报对于水下目标的特征提取和分类识别具有重要意义。由桨叶的旋转引起的湍流场是水下对转螺旋桨流致辐射噪声的源场。分述了水下对转螺旋桨湍流边界层脉动、旋转干涉效应和空化效应引发的水动力噪声机制和研究进展,比较了目前工程应用中的3种对转螺旋桨流致辐射噪声预报方法的特点。在分析对转螺旋桨流致辐射噪声数值预报难点的基础上,综述了对转螺旋桨流致辐射噪声计算方法的研究进展,指出间接数值模拟方法是工程中进行对转螺旋桨流致辐射噪声预报的有效方法。
英文摘要:
      The prediction of the flow-induced noise of the underwater counter-rotation propeller is of great significance for the feature extraction, classification and identification of underwater targets. The turbulent flow field caused by the rotation of the blades is the noise source of underwater counter-rotation propeller. The hydrodynamic noise mechanism and research progress are presented which caused by the turbulent boundary layer pulsation, rotational interference effect and cavitation effect of the underwater counter-rotation propeller. The characteristics of the three propeller noise prediction methods in the current engineering application are compared. Based on the analysis of the difficulty of numerical prediction of the flow-induced radiated noise, the research progress of the calculation method of the flow-induced noise is reviewed. It is pointed out that the indirect numerical simulation method is an effective method for predicting the flow-induced noise in the engineering.
