基于两层流体中内孤立波的KdV-mKdV理论解,采用速度入口和开管道方法进行内孤立波数值造波与消波,建立了同时具有造波、造流和消波功能的数值波流水槽。利用所建立的数值波流水槽,对内孤立波与有航速潜体相互作用问题进行了数值模拟,计算分析了受力特性。数值结果表明,内孤立波造波结果理想,消波效果显著,在内孤立波流场中有航速潜体将会受到突发性冲击载荷的作用。研究表明,利用所述方法来研究内孤立波与有航速潜体的相互作用是一条有效的途径。
Based on the KdV-mKdV theoretical solution of internal solitary wave in a two-layer fluid, numerical wavelets and canceling of internal solitary wave are carried out by means of velocity inlet and open pipe method. A numerical wave flow with wave-making, flow-making and wave-elimination functions sink. The numerical simulation of the interaction between internal solitary waves and a speed submerged submarine was carried out by using the established numerical wave flume. The stress characteristics were calculated and analyzed. The numerical results show that the result of internal solitary wave is ideal, and the effect of wave elimination is remarkable. The speed submergence of the internal solitary wave flow field will be affected by the sudden impact load. The research shows that it is an effective way to study the interaction between internal solitary wave and speed submergence using the method.
