Flow patterns and slug scaling of liquid-liquid flow in square microchannels
Liquid-liquid flow regimes in three square microchannels were visualized simultaneously both at the cross-shaped junction and in the microchannel “far” from the junction in order to reveal flow regime evolutions along the microchannel. At the inlet junction, three major flow regimes including tubing/threading, dripping and jetting were mapped using the aqueous capillary number versus the organic W
