| Abstract: | The characteristics of gas-liquid(liquid-liquid) two-phase flow in microchannels were reviewed.The flow patterns of gas-liquid two-phase flow in microchannels include bubbly flow,slug flow,annular flow and churn flow;the flow patterns of liquid-liquid two-phase flow are categorized into droplet flow,plug flow,parallel flow and annular flow.The parameters influencing the behaviors of gas-liquid(liquid-liquid) two-phase flow in microchannels were analyzed.The flow pattern maps for gas-liquid(liquid-liquid) two-phase flow in microchannels were introduced,and the flow patterns widely used in literature such as slug,droplet and plug flow were particularly introduced.The difficulties encountered in the investigation of gas-liquid(liquid-liquid) two-phase flow in microchannels were pointed out,and the developing prospects of gas-liquid(liquid-liquid) two-phase flow in microchannels were expected. |
