已经研究了由内部孤立波 (ISW) 引起的半潜式潜水器上的力。实验室活塞型造波机在 30 米长的水槽内的密度分层两层流体中产生了一系列 ISW。实验和 ISW 理论模型在频率-幅度关系和波形方面进行了比较。测量了固定半潜式模型上的力和纵摇力矩。根据实验数据，获得经验系数Cman和Cda，作为KC、雷诺数和层深h1/h的函数。力的计算也是基于 Morison 方程和压力积分进行的。计算结果与测量结果有很好的一致性。力和力矩的最大值随着振幅变大而线性增加。此外，发现层深与水平力和力矩的最大值有密切关系。
The forces on a semi-submersible induced by internal solitary waves (ISWs) have been investigated. A series of ISWs were generated by a laboratory piston-type wave maker in a density stratified two-layer fluid within a 30-meter-long wave flume. Experiments and ISW theoretical models are compared in terms of frequency-amplitude relationships and wave profiles. The forces and pitch moments on the fixed semi-submersible model were measured. Based on the experimental data, the empirical coefficientsCmandCdare obtained as a function ofKC, Reynolds number and layer depthh1/h. The force calculation was also performed based on Morison's equation and pressure integral. There is a good agreement between the calculated results and the measurements. The maximums of the forces and moments increase linearly with the amplitude becoming larger. Besides, the layer depth is found to have a close relationship with the maximum value of the horizontal forces and moments.
