An empirical correlation for the prediction of slip velocity in liquid-liquid spray columns, which includes a dimensionless group containing the interfacial tension, is presented. Good agreement between experimental and predicted values of slip velocity is obtained over a wide range of dispersed phase hold-up (0.97–36.2%) and Reynolds number (58-1067).
