AB - Wall-to-bed mass transfer coefficients were computed from limiting current measurements made at inner surface of outer cylinder. Glass spheres of three different diameters viz., 3.13, 4.57 and 6.29 mm were used as bed material. An electrolyte belonging to ferricyanide-ferrocyanide redox system has been employed as the liquid phase. In order to investigate the effect of a change in viscosity carboxy methyl cellulose sodium salt (CMC) was used. Twisted tapes of different pitches and widths were employed as internal elements. The experimental study revealed that the presence of twisted tapes in the fluidized bed brought an augmentation of 25 fold over homogeneous flow and 115% over fluidized bed. It was also found that the effect of pitch on mass transfer coefficient was insignificant. The mass transfer coefficient data increased with increment in tape width and particle diameter and decreased with the rise of CMC concentration. The mass transfer coefficient data obtained from the present experiment were correlated to acquire an equation in jD-Re format using least squares regression analysis.
