摘要
对密度分层流体中周期性内波与水下Suboff潜艇模型的相互作用进行了试验研究。采用摇板方法进行了内波造波试验,对内波的波高和周期进行了测量分析,获得了内波波高与周期之间的对应关系;利用三分力天平对潜体模型在内波作用下的受力进行了测量分析,获得了潜体的内波波浪力随潜深以及周期性内波作用的变化规律。试验结果表明:内波波高、周期对潜体所受的波浪力有显著影响;潜体受到的内波波浪力与潜体在内波流场的相对位置密切相关,其水平力、垂直力和垂向力矩在不同的潜深处呈现不同的特点。
The experimental investigations on the interaction between internal wave and a submerged Suboff model in a stratified fluid is carried out.The height and period of the internal wave generated by the flap type wavemaker are measured,and the relation between the wave height and period is obtained.By use of the measuring transducer of trisection forces or torques,the wave forces exerted by the internal waves on a submerged body are measured quantificationally,so their variations with submerged depth and wave period are derived respectively.Experimental results show that the wave height and period have a considerable influence on the wave loads produced by the internal waves;the magnitude of the wave force or torque exerting on the submerged body is closely related to its location relative to the internal wave flow filed,and all of the horizontal and vertical forces or torque varied with the different submerged depths present its particular load characteristics respectively.
