表面構造パターンと壁面流れ

抄録

The objective of this study is to understand the relation between flow and surface pattern. In the first step to obtain the objective, we visualize the flow around the cylinder array. Two types of array patterns are considered. One is the grid pattern. The other is the checked pattern. We make a comparison between previous studies and ours. The results by grid pattern show that the flow goes to between the cylinders. On the other hand, the checked pattern shows that the flow becomes three-dimensionally. The relation of the interval for the vortex formation behind the cylinder and the pattern of array to understand the flow structure are compared with the previous results.
