Efficient actuation of liquid slugs in microfluidic circuits is a matter of interest in

droplet-based microfluidic (DMF) applications. In this paper, the electrowetting on

dielectric (EWOD) actuation of a liquid slug fully confined...

The influence of two-phase flow patterns especially slug and bubble patterns has been investigated in the recent studies of effect of gas injection on membrane fouling. The consequences demonstrate that slug flow is more effective than bubble flow...

. The two fluids were injected into the microchannel and created either slug or parallel profile depending on the applied conditions. The range of Reynolds and capillary numbers was chosen in such a way that neither inertia nor interfacial tension forces...
