采用连续性方程和Navies-Stokes方程的数值积分方法，研究了孤立波底部边界层的流场。在湍流状态下的流动是在不引入湍流应力的经验封闭的情况下确定的。还确定了向湍流过渡的条件。结果表明，在减速阶段，湍流脉动发生在波峰通过后。
The numerical integration of continuity and Navies-Stokes equations is carried out to investigate the flow field in the boundary layer at the bottom of a solitary wave. The flow in the turbulent regime is determined without introducing empirical closures for turbulent stresses. The conditions for transition to turbulence are also determined. The results show that turbulent fluctuations take place after the passage of the wave crest during the decelerating phase.
