高尔夫球的形状正是空气动力学研究的成果之一。这与球体绕流（即绕球体的流动）的湍流转捩及分离流现象有关。
光滑球体绕流时，湍流转捩发生的晚，与湍流对应的规则流动称为层流。而层流边界层较易发生流动分离现象（即流线离开球的表面），造成球体背后较大的死水区，产生很大的阻力（形阻）。使高尔夫球飞行的距离很小。
而球体表面有凹痕时，凹痕促使湍流转捩发生，湍流边界层不易发生流动分离现象，从而使球体背后的死水区小，减少了阻力。使高尔夫球飞行的距离增大。
湍流的摩阻比层流要大，但与形阻相比，起得作用很小，总的阻力还是变小了。
高尔夫球表面的小突起，也能起到促使分离的作用，但突起对流动的干扰有些难以控制，造成一些侧向力（也可以叫升力）。
球体规则绕流是没有升力的。旋转会产生升力，但打球时，我这样的水平是控制不了的。合适的升阻比会使飞行距离增大。
golf is the shape of the air to study the dynamics of one of the results. the ball and the flow around (namely the flow around the sphere of turbulent flow and unprecedented turn phenomena.
smooth flow around sphere, turn the unprecedented turbulence happen late, and turbulence corresponding rules called the laminar flow. laminar boundary layer and a vulnerable to flow separation phenomenon (i.e. streamline the ball away from the surface), cause behind the larger ball dead zones, generates a lot of resistance (form resistance). make golf flight distance is very small.
and sphere surface have dent, dent turn to unprecedented turbulence happen, turbulent boundary layer, not cause flow separation phenomenon, so that the ball behind the small dead zones, reduce the resistance. make golf flight distance increased.
turbulence in the friction laminar than, but compared with form resistance, up a small role, total resistance or smaller.
golf surface of small, yea, also can have prompted separation function, but the bumps of the flow interference some difficult to control, causing some lateral force (also can call lift).
ball rules there is no flow around the lift. rotation will create lift, but play basketball, i this level is out of control. the right lift-to-drag ratio will make flight distance increased.
