β¦ Synopsis
Recently Jones (1985) presented an analysis to predict liquid circulation in a draft-tube bubble column. Agreement with experimental data was satisfactory for small diameter drafttubes but the model overpredicted at larger diameters. It was suggested that this divergence was in part due to liquid circulation within the draft-tube. The purpose of this note is to present a revised analysis which includes voidage profile effects in the draft-tube, leading to a more accurate prediction of the liquid circulation.

Gas hold-up and liquid circulation rates in a draft-tube bubble column (0.22 m diameter, 85 1 capacity) fitted with various diameter draft-tubes are measured for water and aqueous solutions of ethanol, glycerol and carboxymethylcel~ulose (CMC), respectively. The data are analyzed in terms of a devel
