Gas holdup in bubble columns has been investigated over a wide range of operational and geometrical parameters. A criterion has been developed for the prediction of the transitional velocity from the homogeneous to heterogeneous flow regime. Correlations for gas holdup in both regimes are developed

## Abstract In this paper a CFD model for a bubble column reactor undergoing a first order reaction A β B is developed. The reactor operates in the homogeneous bubbly regime and has a diameter __D__~T~ = 1 m and height __H__~T~ = 5 m. The incoming gas stream contains inerts, varying in proportion f
The conventional two-bubble-class model for bubble column reactors has been modified to account for interactions between the two bubble classes. It is shown that the modified model is more consistent with the observed residence time distribution in the gas phase than the conventional model. The resu
