Laminar Boundary Layer Mass Transfer Across a Spherical Gas-Liquid Interface

11-5 LAMINAR BOUNDARY LAYER MASS TRANSFER ACROSS A SPHERICAL GAS-LIQUID INTERFACE 

Mass transfer across a perfect-shp zero-shear interface at high Schmidt numbers is discussed in light of the previous results for no-slip interfaces. The following assumptions are invoked to develop the model  

The bubble is stationary and its radius R remains constant during the analysis. Surface stretch is not considered in response to a decrease in fluid pressure that one encounters if, for example, the bubble rises. 

The fluid is Newtonian and incompressible, and its approach velocity approach remains constant in the creeping or laminar flow regimes. 

Analysis is performed at steady state for a nonreactive mixture.
