水动力噪声计算方法综述
A review of the progress for computational methods of hydrodynamic noise
摘要
Abstract
It is of great importance to accurately evaluate submarine's hydrodynamic noise in order to de⁃velop anti-submarine surface warships, stealthy submarines and torpedoes as well as to optimize their hy⁃drodynamic and acoustic performance. Specifically, the three dimensional unsteady flow field over the vehi⁃cle is usually caused by the changes of profile, discontinuity of surface curvature, and various perturba⁃tions. In this paper, the research progress of the vehicle's hydrodynamic noise induced by the turbulent boundary layer on the surface, cavity oscillations, cavitation, and roughness are introduced, respectively. By analyzing the difficulties in the numerical prediction of hydrodynamic noise, different computational methods of flow induced noise are summarized. A comparison is finally made among three methods in par⁃ticular, all of which are potential schemes that can be applied in predicting vehicle's hydrodynamic noise.关键词
