Slug Formation in Microchannel

A demo of how water slugs in oil are formed using a Y-shape microchannel.



This is a water-in-oil system in which water slug is formed in a continuous phase of oil.

Continuous phase:
•A fluid phase which wets its contact walls and carries a suspended immiscible phase along its direction of flow.

Dispersed phase:
•A suspension phase that disperses in another phase of carrier fluid.

Surface tension is a domineering force that governs the formation of slugs in an immiscible fluid system.
