Fluid mechanics of supercritical carbon dioxide with water in a double-y-channel microfluidic chip

• In this paper, three flow regimes in thesupercritical carbon dioxide-water two-phase microfluidicsystem are mapped. The effect of both totalflow rate and relative flow rate on the flow regime isevaluated. Furthermore, the droplet dynamics at thebifurcating exit channel is analysed at different flowrates. The influence of the capillary number ondroplet splitting at the exit is also evaluated.
