This simple theoretical model for the hydrodynamic behaviour of bubble columns is based on an energy balance which takes into account the energy dissipated both in liquid motion and at the gas-liquid interface. Gas hold-up, liquid velocity at the column axis, and the liquid velocity radial profile, are predicted for superficial gas velocities of up to 1.452 m/s, and column diameters and heights of 0.1-1.0 m and 1.22-9.5 m, respectively. Predictions of liquid velocity are compared with those predicted by Kawase and Moo-Young. MacMillann
