The study of CFD on aerodynamic characteristics of freestyle skiing athletes in the curve slideway period

摘要

In order to explore the aerodynamic characteristics of athletes in the aerials event of freestyle skiing sliding on the platform, to provide aerodynamic parameters for the calculation on leaving platform speed, the essay makes use of the CFD method to study on aerodynamic characteristics of Chinese freestyle skier Mengtao Xu in the curve slideway period. The results show that: The lift of athletes in the curve slideway period can be neglected, and the resistance can't be neglected because it is relatively large. With the common superposition of resistance and own gravitational tangential component, the athletes sliding speed will decay rapidly. In addition, to improve the stability of athletes' movements on leaving platform, athletes should try to keep away from the eddy zone formed by the slope on leaving platform and the angle area of the vertical wall.
