Most authors publishing numerical calculations for the flow field claim that scientific progress on liquid mixing in bubble columns must be based on the fluid dynamics.

An expaimental study has been aimed at Linking the extent of axial mixing m gas and liquid phas~ m tall bubble coltmm reactors with the respective bubbling regimes (homogeneous, tr~msition, hctcrogeneous) Β’ncotmtered in such reactors and with correnpondhag macro-scale flow patterns of b~h phases.

Gas hold-up and liquid phase axial dispersion coefficient have been measured in water filled bubble columns of 5.08, 14.0 and 29sOcm dia. as a function of the superficial gas velocity. From the gas hold-up measurements the following relationship between the relative velocity between gas and liquid,
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
