AN EXPERIMENTAL-STUDY OF MASS-TRANSFER FROM A SPARINGLY SOLUBLE CYLINDER IN CROSS-FLOW CONFIGURATION

Mass transfer coefficients from sparingly soluble cylinders in cross h ow configuration have been measured experimentally. The contributions stemming from the different parts of the cylinder namely, front, rear and side regions, have been isolated by appropriately masking the part s of the cylinder. Predictive expressions have been developed for the componentswise as well as total mass transfer coefficient. Also, the p resent results are compared with the previous literature data wherever possible. The results reported herein embrace the following ranges of kinematic and physical conditions: 80 less than or equal to Re less t han or equal to 900; 850 less than or equal to Sc less than or equal t o 1520 and 60 less than or equal to Sh less than or equal to 520.
