Balls used in ball games have various surface structures that affect aerodynamic characteristics. In soccer, a new ball is developed for each global competition, and the aerodynamic characteristics differ because the panel shape and surface structure of the balls are different. In the author's research, the aerodynamic characteristics in the non-rotating balls were evaluated using a model ball in which the groove depth and groove width were systematically changed. However, the ball in the actual game is rotating, but the aerodynamic characteristics in the rotating state to the aerodynamic characteristics are still unclear. In this study, the effects of groove depth and groove width on a soccer ball in a rotating state are clarified.
