摘要: 鉴于气液两相螺旋流在实际中的重要作用,以及目前国内外对其鲜有研究报道,以空气和水为实验介质,利用高速摄像机对在不同起旋参数下的水平管内气液两相螺旋流的流型进行了研究。依次得到螺旋波状分层流、螺旋泡状流、螺旋团状流、螺旋线状流、螺旋轴状流、螺旋弥散流6种典型的流型图像,并绘制了流型图。着重讨论了流速、叶轮起旋角度、叶片大小等对流型转换边界和流动压降的影响,为今后的研究奠定基础。

Abstract: In view of the importance of the gas-liquid two-phase spiral flow and the few research report at home and abroad, gas-liquid two-phase spiral flow patterns have been researched in the horizontal pipe with the different parameters by ways of observation and high-speed camera. The appearance of spiral flow makes the distribution of two-phase flow more complex, the flow patterns appeared in the experiment were divided into Spiral Wave Stratified Flow (SWS), Spiral Bubbly Flow (SB), Spiral Slug Flow (SS), Spiral Linear Flow (SL), Spiral Axial Flow (SA), Spiral Dispersed Flow (SD) by our observation and references on the predecessors' research achievements. The flow pattern map has been drawn. The influence of velocity, vane angle and vane area on flow pattern conversion boundary and pressure drop have been researched, and the future research has been laid the foundation.
