设计了不同内部流动结构的单、双层多孔层板 ,并针对这些层板在吸气式风洞上进行了流阻实验 ,得出了绕流柱形式、开孔率、孔间距、绕流柱高度以及单、双等敏感因素对层板流阻特性的影响 :方形扰流柱阻力最小 ,圆形次之 ,菱形阻力最大 ;开孔率越大 ,孔间距越小 ,流阻越小 ;扰流柱越高 ,流阻越小 ;双层扰流柱的层板阻力明显高于单层扰流柱。 The single and double-layer porous laminae with different internal flow structures were designed and the flow resistance experiments were carried out on the aspirated wind tunnels for these laminates. The results of flow-around column, open area ratio, pore spacing, Column height and single and double sensitive factors on the flow resistance characteristics of the laminates: square interference column has the least resistance, followed by the circle, the diamond resistance is the largest; the larger the hole opening ratio, the smaller the hole spacing, the smaller the flow resistance; The higher the spoiler flow, the smaller the flow resistance. The resistance of the double deck spoiler is obviously higher than that of the single spoiler.
