Number of dimplesPressure coefficientSpark tracing methodCFDIt is known that the flying characteristics of the golf ball are influenced by flying speed, rotational frequencies and the number of dimples, etc. In this study, the pressure acting on a test spheres is measured using a pressure ...
A direct comparison of features of flow fields was made to a smooth sphere model. Particular attention was paid to the effect that the golf ball dimples have on the development of lateral force and wake structures. In the subcritical regime, the lateral force varies irregularly in time for ...

of flow separation.Dimple structures are successfully employed in golf balls to reduce the pressure drag and provide longer flight.The study of aerodynamics of golf ball showed that the dimples created localized turbulence which resulted in delayed flow separation.Changes in flow characteristics of NACA...
However, the surface roughness could result in the drag crisis of golf ball occurring at a lower Reynolds number in the supercritical regime compared with the smooth sphere. This is because the flow becomes instable when it passes the dimples at the supercritical Reynolds number and could ...
