Abstract :
The present microfluidic study is emphasizing the flow behavior of two immiscible fluids within a microchannel with three inlets and one outlet. We report here a numerical investigation on the interface shape dynamics manifested at different flow rate ratios (FRR) over the inlets. Changing only the FRR of the inlets, the droplets behavior modifies drastically. From the numerical point of view, the interface shape is used to characterize the manifestation of droplet formation.
