A dimensionless dispersion number was developed to characterize liquid‐liquid dispersions created in turbulent Couette flow with respect to their subsequent coalescence in a settling zone. For a given solvent pair and continuous phase, the dispersion number is relatively constant over a wide range of operating and dimensional parameters. Because of this, the dispersion number can be used for the design and scale‐up of liquid extraction equipment with discrete stages.
