摘要：

Mass transfer at a vertical gas sparged electrode with and without superimposed electrolyte flow has been investigated. The mass-transfer coefficient depends only on the gas voidage fraction, irrespective of the absolute values of the liquid flow velocity and the gas flow rate. The system has a strong similarity with turbulent free convection. The results can be represented by an analogous correlation in which the Grashof number, characteristic for free convection, is replaced by a modified Archimedes number: Sh = 0.19(Sc.Ar*) 1 3. © 1979.
