Simulating results show that laminar, turbulent and wavy flow states are simultaneously subsisting in the evaporating liquid thin-film, and turbulence appears in the arched wave before wipers.
模拟结果表明，蒸发液膜呈现层流、湍流、波动流等复杂流动形态，湍流主要出现在刮膜器前的弓形波内。

Like in an infinite flow, we find that laminar boundary layer, transition region and turbulent boundary layer also exist along a flat plate in open channel flow boundary layers.
The characteristic parameters of fluid during the transition in boundary layer are obviously different from that of the laminarflow or the turbulent flow.
