为了弄清亚破碎波的力学机理,通过实验研究了一个由水下翼片产生的二维波浪。它是一种发生在波峰周围的自由表面紊流。当波陡突然增加后,便产生这一流动。这时有一个最大波峰角。它表现为沿自由面有一层具有显著紊动强度的向前的流速。以下讨论都是建立于当这一流动已经产生的情况。
In order to understand the mechanical mechanism of sub-wave, a two-dimensional wave generated by the underwater wing is experimentally studied. It is a turbulent free surface that occurs around the crests. When the wave steep suddenly increased, it will produce this flow. At this time there is a maximum peak angle. It appears as a layer of forward flow with significant turbulence along the free surface. The following discussion is based on what happens when this flow has occurred.
