摘要
本文通过实验测量柱表面的脉动压力，获得了在高雷诺数范围中（4．19×104＜Re＜5．77×105）串列弹性双圆柱体（2．5＜L／D＜5．02）及孤立弹性圆柱体在均匀流场中的脉动升力和阻力。实验发现，在高雷诺数区中串列弹性双圆柱体的脉动升力与阻力与孤立弹性柱有较大的差异。
Based on the measurements of the surface fluctuating pressure, this paper gives the fluctuating lift and drag of an isolated circular cylinder and two tandem elastic ones with the same diameter at high Reynolds numbers (4.19×104<Re<5.77×105). The test results show that there is a great difference between the fluctuating lift and drag coefficients of the tandem cylinders and those of the isoluted one.
