S0504-1-1 ワールドカップ公式球JABULANIの空力特性について([S0504-1]スポーツ流体工学)

抄録

The panel architecture of the soccer balls used in the World Cup has changed in every four years' convention. It is understood that the change in the panel structure in the soccer ball exerts a big influence on the aerodynamic characteristics. It is well known that the non-rotatinal shot by "TeamGeist" appeared in 2006 becomes a oscillating ball in the long or middle distance shot. However, the aerodynamic characteristics of the 2010 official ball, "JABULANI" has not been reported yet. In this study, the aerodynamic characteristics of "JABULANI"in the non-rotational shot and the possibility of the blur ball are verified.
