Performance of an ejector system in a two‐phase downflow bubble column has been evaluated with respect to the energy dissipation during coaxial flow of liquid and gas in a parallel throat and divergent diffiser and during gas—liquid mixing in the column. Experiments were carried out in a 51.6 mm i.d. column with five different nozzles. Three systems, namely air—water, air‐kerosene and air—paraffin were used. Correlations have been developed for predicting the ejector loss coefficient as well as mixing loss coefficient as a function of different physical and dynamic variables of the system.
