Abstract
In a previous paper2}, the effect of gas and liquid flow rates on mass transfer rate in laminar gas streams in wetted-wall columns with cocurrent gas-liquid flow was studied theoretically and experimentally. An analytical solution was obtained for the average gas-phase Sherwood number ShG as a function of the gas-phase Graetz number GzG and the dimensionless inter facial gas velocity U. This analysis, however, is not applicable to the case of U>2 where circulation exists in the gas phase. The purpose of this short paper is to present an approximate analytical solution for the present case and to confirm this approximate solution experimentally.
