Abstract: The flow regimes of water and crude oil in a Y -type microchannel were studied in a wide range of flow rates. Four different types of water-oil flow regimes have been identified: plug, droplet, parallel and chaotic. The ranges of existence of these flow regimes have been determined. Dependences of the length of water plugs and droplets in oil on various parameters have been established. Maps of the corresponding water-oil flow regimes have been constructed.

Keywords: Y-microchannel, liquid-liquid flow, immiscible liquids, flow regime map.
