Golf Ball Construction
Most golf companies these days use all different types of materials in the core and even the cover of their golf balls. All golf balls are designed with dimple patterns on the cover to optimize the ball’s aerodynamics and wind resistance. The dimples can control many different aspects of shots like distance, velocity, spin control, straightness and trajectory.
There are two types of drag behind a golf ball when it is airborne, laminar and turbulent. Laminar flow occurs over a non-dimpled ball and the air separates very early in front of the ball, resulting in less carry. A turbulent flow will occur with a dimpled ball because it causes the air to not split as soon and increases the pressure drag. Pressure drag is the air separated behind the ball.
The surface roughness allows the flow to change from laminar to turbulent, resulting in more energy and allowing the flow to remain attached longer than laminar. In other words, the dimples allow the ball to be carried farther by the air.
