... water in oil churn flow (W/O CF), dispersion of water in oil (D W/O) and very fine dispersion of water in oil (VFD W/O). Fig. 4 shows a schematic representation of the vertical oil-water flow patterns. A flowpattern map in terms of superficial velocities of oil and water is given in Fig. 5 . Fig...
