In view of the importance of gas-liquid two-phase spiral flow and the few research reports at home and abroad,the gas-liquid two-phase spiral flow pattems have been researched in a horizontal pipe with different parameters investigated by means of observation and a high-speed camera.Since the appearance of spiral flow makes the distribution of two-phase flow more complicated,the flow patterns appearing in the experiments were divided into the Spiral Wavy Stratified Flow (SWS),the Spiral Bubble Flow (SB),the Spiral Slug Flow (SS),the Spiral Linear Flow (SL),the Spiral Axial Flow (SA),and the Spiral Dispersed Flow (SD) by the observations and with reference to the predecessors research achievements.A flow pattern map has been drawn up.The influence of velocity,vane angle and vane area on flow pattern conversion boundary and pressure drop has been studied,with a solid foundation laid for the future research work.
