Energy efficiency of gas-liquid-solid mixing in a plunging liquid jet slurry bubble column

Mekala Sivaiah; Rajeev Parmar; Subrata Kumar Majumder

This article presents the analysis of the energy efficiency of the gas-liquid-solid three-phase mixing in an ejector-induced downflow bubble column. Experiments were carried out with air-aqueous Solution of solids (Kieselguhr, Zno and Al2O3) with different concentrations. Energy dissipation coefficient of mixing has been correlated as a function of different geometric, dynamic and physical variables of the system.
