摘要：
The experimental study of adiabatic two-phase gas-liquid flow in an extremely small gap microchannel with a height of 10 mu m and width of 10 mm has been carried out. Color schlieren visualization allows the registering of typical flow patterns: Jet-Droplet, Jet-Churn, Churn, and Droplet-Annular. Flow patterns have been described and flow pattern maps have been created and compared with those of gap microchannels of higher sizes. The interference pattern of thin liquid films makes it possible to distinguish two mechanisms of their creation. New features and flow patterns are revealed that were not observed in larger gap microchannels. Liquid droplet sizes have been studied. It is shown statistically that with an increase of superficial liquid or gas velocity, the droplet size distribution is shifted towards smaller sizes.
