| 抄録 | Many studies have examined the aerodynamics of soccer balls. In most of these studies, experimental balls are supported by three methods: piano wire, cobra support, and wire support. The purpose of this study is to clarify the influence of the support methods on aerodynamic characteristics of balls, wire support and piano wire. The results show that, the drag coefficient of balls supported by piano wire is higher than that of balls supported by wire support in the supercritical region for smooth balls or balls with no grooves. However, there is no difference in drag coefficient for balls supported by wire support and piano wire in all regions for balls having panels or grooves. In addition, the side force of all balls supported by piano wire is higher than that of balls supported by wire support, due to the vibration in all directions. |
