A physical model is presented which descri'bes the local mixing in the liquid phase of twophase gas-liquid flows agitated by rising bubbles. It corresponds to the stochastic mathematical model descrii by Nassar et al (1992). The transport of liquid in the bubble wakes is assumed to be the dominating

## Abstract This article deals with the physical modeling and numerical simulation of twoโphase bubbly flow in an airlift internal loop reactor. The objective is to show the ability of computational fluid dynamics (CFD) to correctly simulate hydrodynamics and axial dispersion in such a bubbly react
