The surfactant has obvious effect on the transition from stratified wavyflow to annular flow.
结果表明，表面活性剂的添加明显影响波状分层流向环状流型的转换；

With the variation of flow rates and qualities, the flow patterns can be divided into bubbly flow, plug flow, stratified-wavyflow, intermittent flow and annular flow.
随着流量和干度的变化，流型可划分为泡状流、塞状流、分层波状流、间歇流以及环状流。

Simulating results show that laminar, turbulent and wavyflow states are simultaneously subsisting in the evaporating liquid thin-film, and turbulence appears in the arched wave before wipers.
