注:
高尔夫球知识
高尔夫球表面有意制造了许多的凹痕。
高尔夫球的形状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。合适的升阻比会使飞行距离增大。不同的旋转方向会造成“香蕉球”的效果。
另外高尔夫规则规定高尔夫球不得被设计、制造或有意更改为具有不同于球体对称性的球的特性。
