形状の異なるフライングディスクの流れ解析

抄録

Recently the sport using flying disc is enjoyed in the world. Flying disc has the peculiar aerodynamic characteristic different from other throw things. Therefore the flight mechanism of Flying disc wasn’t understood still unclear. Elucidation of a flight principle of flying discs leads, ideal throw form of the disc and development of good Flying discs of the flight performance. In this research, CFD analysis was performed on three kinds of flying discs (for flight stability, flight distance, duration). By the CFD analysis, fluid force of the disc was calculated and the flow around the disc was visualized. From the calculation result, we have grasped the aerodynamic characteristics of each flying disc. And the factor of fluctuation of fluid force were mentioned by visualizing a flow around the disc.
