平織金網の後流の渦挙動に与える開口比の影響

抄録

The wire mesh has a rectifying effect, and the parallel two-sided grid has a turbulent effect. This each effect is a fully developed area, and the transition process to that region has not been clarified. The purpose of this experiment is to clarify the transition process of the wire mesh wake. As the result, it was shown that there is a locally fast secondary flow in the wire mesh wake with the large open area ratio and that the direction of the secondary flow is different. It is considered that the structure of this secondary flow affects the rectification effect.
