Abstract
Drag across a golf ball can affect distance traveled when hitting a ball. An average golf ball will have a drag coefficient of, 0.24 < C D < 0.7, in a Reynolds number range of 30,000 < Re D < 108,000. This paper investigates the effect of dimple patterns on the boundary layer around a ball. Changing the depth of the dimple will cause a change to the drag coefficient. A deeper dimple pattern will cause a larger drag coefficient at higher velocities, u > 35 m/s. This research found that a significantly deeper dimple pattern will greatly affect the boundary layer, thus changing the drag coefficient and boundary layer.
