Abstract
A general kinetic transport equation for the description of gas-liquid two-phase flows is presented. This formulation accounts for mechanism s of interfacial area variation due to breakup and coalescence of bubb les. Within this formulation, a model of discrete bubble volumes is ap plied to the analysis of a column of rising bubbles. Predictions of th e development length are in accordance with existing data.
