摘　　要：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.The comparison between the liquid circulation model and the reported experimental data shows that the liquid circulation model based on the modified model of eddy viscosity distribution not only agrees with the data very well but also has a wide application range.In addition, the determination of the model parameters is discussed according to the simulation for the reported data with this model.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.
