摘要

摘要: 在曲线网格下基于粘声分离方法对流场中的静止圆柱同声波和涡波的相互作用进行研究.首先推导了曲线坐标系下、适用于水流噪声的粘声分离方法（viscous acoustic splitting method,VASM）控制方程，并采用7点色散关系保持(dispersion-relation preserving, DRP)格式和四阶时间差分格式进行计算.然后将静止流场中圆柱壁面对声波反射的计算结果同理论值进行比较，验证了计算方法模拟水中物体对声波散射的准确性.进而模拟了旋涡行走发声的特性，并分析了流速等对声场特性的影响.

Abstract: The viscous acoustic splitting method on curvilinear meshes was developed for hydrodynamic noise calculation related to the interaction between a stationary cylinder and sound waves as well as vortex waves in flow field. The 7-point dispersion-relation-preserving (DRP) difference scheme coupled with the classical 4th-order Runge-Kutta scheme, was implemented to solve the governing equations for the simulation of hydroacoustic phenomena. The propagating acoustic pulse reflected by the stationary cylinder was computed and compared with the theoretical results to demonstrate the validity of the calculation strategy. The flow noise generated by the vortex in inhomogeneous water flow and the interaction beteen the vortex and the cylinder were studied to analyze the effects of the vortex core size and the incoming flow velocity on the acoustic filed. The work lays a foundation for the precise calculation of hydrodynamic noise in flow past immersed bodies.
