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,
