In two bubble columns of different diameters with three different gas distributor types, specific interfacial areas were determined simultaneously by the photographic and the sulfite oxidation method. Gas velocities of up to 18 cm s-1 were applied and CMC was added to vary the viscosity. The areas obtained by the photographic technique are always larger the discrepancy increasing with the gas flow rate. The differences have been explained by maldistribution of the bubbles and systematic underestimation of the Sauter diameters of nonspherical bubbles. Even in the homogeneous (bubbly) flow regime, i.e., at low gas velocities, this leads to significant errors in the results of the photographic method. |
