Effect of dimples on a golf ball and a car (original) (raw)

The purpose of this review is to determine the effect of dimples on the drag force on a golf ball and a car. Dimpling a golf ball and a car has reverse effects on the drag. Presence of dimples on a smooth ball causes a reduction of the total drag on a golf ball. Although no study on the effect of dimples on the drag on vehicles was found, inference were drawn from studies conducted on an airfoil (streamlined body). We discuss how an increase in surface roughness of a streamlined body leads to an increase in drag. Since most recently built cars are streamlined, it was concluded that introducing dimples on a car would lead to an increase in drag.
