説明

<p>The surface of a golf ball is provided with innumerable dents called dimples to improve the flight distance. I think that these dimples can show the state by the dimple surface occupancy and the dimple volume ratio. Therefore, we will manufacture a model ball in which the dimple surface occupancy is changed by the dimple diameter and the number of dimples, and the dimple depth is changed to change the dimple volume ratio. Using them, we will carry out a lift and drag measurement experiment by a wind tunnel experiment. Then, a flight trajectory simulation was performed based on the obtained experimental results, and it was clarified how the dimple surface occupancy and the dimple volume ratio affect the flight distance.</p>
