車椅子マラソンにおける姿勢と空力特性

抄録

In recent years, fluid dynamics has been important in the competition to compete for speed .Wheelchair marathon to finish the race in 1 hour 30 minutes about the 42.195 km. For record improvement, they take various invention to change the shape of wheelchair to reduce air resistance. In this research, the air resistance of helmet and posture by the wheelchair marathon by were investigated by using computational fluid dynamics (CFD). Also, ass for the rear wheel of the wheelchair, three types of wheels, such as disk wheel, baton wheel and spoke wheel were investigated on the air resistance. As a result, the appropriate postures, helmets and wheels could be suggested on the air resistance in the wheelchair marathon.
