【摘要】 针对串列弹性双圆柱(L/d=2．5、3．0、4．0、5．0)在1．5×105≦Re≦5．5×105,波高(H)为15cm、20cm、25cm、 30cm、40cm的波流联合场中的阻力和升力进行了实验研究。通过测量柱体表面的压力分布来研究柱体受到的流体载荷变化特性,并与孤立弹性柱受到的流体载荷做了对比。实验对比分析结果表明:在波流联合场作用下阻力和升力与Re数密切相关,并且弹性柱体的柱间干扰效应使其流场交得更为复杂,不能忽略柱问的相互干扰。更多还原

【Abstract】 In this paper, the drag and lift forces of flexible circular cylinders in tandem arrangement subjected to wave-current flow are investigated experimentally in the range of 1.5×105≦Re≦5.5×105,15cm ≦ H≦40cm. The changing characteristic of drag and lift forces is analyzed and researched by measuring the surface pressure distribution, and at the same time the characteristic of tandem cylinders is compared with the single cylinder. It is shown from the experimental analysis that drag and lift forces of flexible cylinders are closely related with Reynolds number. Moreover in the present research, spacing of flexible cylinders is not neglected.更多还原
