Hydrodynamics of Two-Phase Immiscible Flow in T-Junction Microchannel

In this study, a numerical investigation of droplets’ formation and their hydrodynamics of the two-phase immiscible flow has been performed in a T-junction microchannel using the conservative level set method for a broad range of flow governing parameters. The flow dynamics is described by the time evolutions of the pressure profiles for various flow regimes like squeezing, transition, parallel and jetting. The findings are presented as phase contours and pressure profiles. The pressure value in the continuous phase is coming closer to the dispersed phase when the droplet breakup is happening in the droplet zone. On the other hand, the pressure profiles exhibit contrasting behavior in the non-droplet zone. Insights of the present study help design microfluidic devices precisely.
