Drag Coefficients of Golf Balls

1. Introduction. Six golf balls were tested in a wind tunnel and Star CCM+ was used to simulate how the golf balls drag coefficients, C D, varied with Reynolds numbers, Re D, in relation to the flow around the balls.The six golf balls were chosen, each with different surface configurations, to determine the effect of surface finishing on the drag coefficient of the ball.
