潜艇近水面航行兴波特征研究

摘要

Submarine, which is a kind of underwater vehicle, can induce a much more complicated flow field com-pared with the other conditions when it is traveling near the free surface and the effect of the submarine on the free surface is important. The viscous computational method is adopted in the present paper, in order to simulate the viscous flow field around the submarine. The wave form of the free surface is calculated accurately in this manuscript, and the characteristics of the induced wave are analyzed particularly. The characteristics of the wave induced by the submarine sailing near the free surface and some conclusions are obtained by the research.%潜艇作为一种水下航行器，其近水面运动时产生的绕流场远比无界直航运动时要复杂得多，其近水面航行时对自由液面的影响不容忽视。本文采用粘性流体力学计算方法，对SUBOFF潜艇近水面航行时的粘性绕流场进行模拟，对自由液面的兴波进行计算，并对波形特点进行深入分析。通过本文的研究，得到潜艇近水面航行时自由液面兴波的特点和相关规律。
