摘要
本文针对壁面开槽复合多孔介质强化传热的实验条件 ,将整个流动区域划分为多孔介质填充区和纵向微槽区两个区域 ,通过数值计算分析了这种复合多孔介质结构的流动特性 ,考察了微槽宽度、深度等有关因素的影响 ,得到了与实验相一致的结果。
According to the conditions of experimental study on heat transfer enhancement between parallel plates packing beads with mini longitudinal channels at the surface, the whole region was divided into two regions, one filled with beads, the other with mini longitudinal channels near the plate wall. The fluid flow characteristics in this kind of composite porous media was numerically analyzed, the influence of variaus tactors, such as the width and depth of mini longitudinal channels, were discussed. The results of model analysis agree with those of experiments.
