Residual film thickness following immiscible fluid displacement in noncircular microchannels at large capillary number
An experimental study of the displacement of one immiscible fluid by another was performed in microchannels with circular, square and near-semicircular cross-sections, with hydraulic diameters from 100 to 200 m. Experiments were performed over a range of capillary number, Ca, from 0.02
