| 摘 要： | 分析水平阻力与内波波要素的关系,采用实验室实验的方法,研究了水平桩柱与内波的相互作用,焦点是研究内波波要素与波阻之间的关系。实验中的密度分层采用典型跃层型剖面,而内波是由自行研制的造波机生成。实验结果表明,当内波的频率不变时,水平桩柱所受到的阻力随着内波的振幅增加而增加,它的量值与分层有关。对于强跃层的密度分布,当桩柱处在跃层中时,受到的水平波阻较小,而在跃层之外则受到较大的水平波阻。

| Abstract: | The interaction between internal waves and a horizontal cylinder is studied by using a laboratory experiment,the focus being the dependence of the factors of the internal waves on the resistance of the horizontal cylinder induced by the internal wave.In this experiment,typical pycnocline-type profiles are employed,and the internal waves are generated by a wave maker designed by the authors.From the experimental results it can be seen that as the frequencies are kept unchanged,the horizontal resistance of the horizontal cylinder exerted by the internal waves increases with increasing amplitude of the internal waves,and its magnitude depends on the stratification.For a strong pycnocline,the horizontal resistance is small when the cylinder is in the pycnocline and it is large when the cylinder is outside the pycnocline. |
