This paper proposes a modified model of eddy viscosity distribution for liquid flow in bubble columns based on a relationship from single-phase flow and then develops a liquid circulation model for bubble columns.

Gas holdup and liquid circulation in an internal airlift loop reactor were investigated.

A new model describing liquid circulation in bubble column reactors is developed with the concept of seperated flow.
