内容記述 | Abstract It is well-known that a soft tennis ball hit with topspin tends to curve down, but we often experience a wetted ball appears to bend upward on rainy days. The purpose of the present study is to understand this puzzling motion. First, we observed a trajectory of a falling wetted circular cylinder suspended with a thread, from which the aerodynamic force coefficients were estimated. Using these values, trajectories of the flying dry and wetted soft tennis ball were simulated by a finite difference method. It was found that the wetted ball with topspin does not bend upward, but travels in a significantly flatter trajectory. |
