作用在并列双矩形柱上的平均风荷载(英文)
Mean Wind Loadings Acting on Two Rectangular Cylinders of Side-by-side Arrangements
【摘要】 本文通过实验研究给出了并列双矩形柱在各种高宽比和间距时,在流体作用下的表面压力分布,力和流动量显示等的结果。矩形柱高宽比自0.3至5,两柱间距比自1至5。其中特别对在一定间距比时出现的双稳态偏流现象进行了详细的讨论。
【Abstract】 This paper presents the results and discussions of the experimental investigation of the surface pressure distributions, forces, and flow visualization of two side-by-side rectangular cylinders of slenderness ratios from 0.3 to 5 for gap ratios from 1 to 5. Special attentions are given to the bistable biased flows which appear during certain range of gap ratios.
