A-11 シャトルコック後流での渦の挙動と流体力特性(テニス・バドミントン1)

抄録

Today the game of badminton is so popular that over 160 countries are now the official member of the Badminton World Federation (BWF), and the badminton is one of the oldest and popular sports in the world. The aerodynamic characteristics and the flight trajectories of badminton shuttlecocks are significantly different from balls used in other racquet sports. A badminton shuttlecock is an extremely high drag projectile and possesses almost parabolic flight trajectory. In the present study, in order to understand qualitatively the behavior of the shuttlecock during its flight, the relationship between the aerodynamic forces and the vortex behavior in the wake is investigated for wind tunnel tests. Furthermore, the impulsive rotational movement of the shuttlecock simulating the condition just after the impact in badminton stroke is also measured. The shuttlecock behavior is significantly affected by the vortex dynamics in the wake.
