Abstract

The pressure distribution of airflow field around tennis and the characteristics of gas under various rotational velocities and flight conditions of tennis are simulated by the method of computational fluid dynamics(CFD) andtherelational software fluent 14.5 is used. Then the pressure distribution on the upper and lower surface of tennis are analyzed point by point. The results indicate thatdifference in pressure between the upper and lower surface of tennis increases with the increase of rotational speed,which can enhance the effect of Magnus force and causethe rapid falling of tennis.The increase of tennis speed will disorder the flow of the surrounding gas, result in the worse motion movement controllability oftennis, and change the motion trajectory. The static pressure distribution on the upper and lower surfaces oftennis is similar, but the change of pressure for the lower surface is slightly behind that of the upper surface. The drag coefficient and lift coefficient increase with the increase of the tennis speed and the rotational velocity, respectively.
