摘要
本文阐述了水下流噪声产生的机理以及物体表面状态性能对湍流边界层的影响。对近年来的减阻降噪措施进行了简要的评论后,特别指出了低壁面相互作用涂层可减小壁面的切变应力,增大排挤厚度,从而降低航行体的阻力和噪声。这种涂层还具有优异的耐水性和耐候性,应作为一种实用的降噪措施给予足够的重视。
In this paper, the mechanism of flow noise production and the methods of flow noise reduction are presented. Especially, using coating of low bond can decrease the tensile strength of interface between water and the surface of solid materials, increase the boundary layer thickness. Thus, it reduces friction force and flow noise of the motive body.
