海洋内波的相似性分析

Similarity Analyses of Ocean Internal Wave Research

应用量纲分析理论对层化海洋中的内波荷载和潜体运动兴波问题的相似性进行了分析 结果表明,把结构物视为刚体并不计流体粘性,可以做到模拟的完全相似 当考虑物体的弹性时,若在刚度控制的范围内,则实验可按抗弯刚度的相似准则进行 当考虑流体的粘性效应时。

With the dimensional analyses theory,the similarity analyses for internal wave load and wavemaking generated by the submarine in the stratified ocean are made.The analyses show that,the perfect similarity may be achieved if regarding the structure as a rigid body and not considering the fluid viscosity.If the elasticity of the body is considered,one could take the similarity of the antibend rigidity while problem is in a range of rigiditycontrol.If the effecl of the fluid viscosity is considered,then the experiment can be controlled according to the principle of the critical Reynold number .
