Enhancement of immiscible fluid mixing using passive micromixers to increase the performance of liquid–liquid extraction

This paper aims to simulate an immiscible two-phase flow in two-dimensional T-shaped, modified cross-shaped, and cross-shaped micromixers numerically. The effects of various parameters, including Capillary number, phase rate ratio, channel width on the generation droplets were studied. Also, modification T-shaped was proposed. results reveal that equidistant tiny are generated compared ordinary geometry under same conditions. Three types squeezing regime, laminar jetting regime observed different values capillary number. It also droplet size decreases with increase Moreover, this study demonstrates multiphase flows micro-devices very sensitive even small changes geometry.
