抄録

It is known that low rotating or no-rotating balls have the erratic ball path especially in the new different panels of soccer balls. Dynamic velocity distributions of the balls wake wake were measured by PIV on three types of different balls of the panel. As a result, the velocity distributions of the wake changes varied according to the difference of the ball panel. On the ball which causes big change, a big three-dimensional twins vortex was found to be generated.
