Hydrodynamic relations arising from single droplet movement in a RDC geometry are described. These relations can be regarded as the basis for a general estimation strategy for the determination of dispersed‐phase flow parameters in connection with droplet population balance modeling. Droplet population balance based modeling of countercurrent liquid‐liquid extraction columns offers a considerable advance in describing the real droplet swarm behavior. The main problem encountered is the determination of the characteristic droplet model parameters.
