对平行平板间填充小颗粒后的流动实验结果进行了归纳和分析 ,表明流动阻力远远小于微颗粒填充 ,同时在小的颗粒填充层数下 ,壁面效应对流动阻力特性有显著的影响 ,流动呈现出与细微颗粒堆积多孔介质不同的流动规律。在实验结果的基础上 ,通过定义壁面修正因子考虑壁面效应的影响 ,得到了颗粒堆积多孔介质在小填充层数时流动阻力特性的准则关系式 The results of flow experiment after filling small particles between parallel plates are summarized and analyzed. The results show that the flow resistance is far less than that of micro-particles. At the same time, the wall effect has a significant influence on the flow resistance characteristics under the small particle- It exhibits a different flow pattern than finely divided porous media. Based on the experimental results, by considering the influence of the wall effect by the wall modification factor, the relationship between the flow resistance characteristics of the porous media with small packing layers is obtained
