Abstract
Mass transfer coefficient is numerically obtained for a laminar boundary layer flow with tangentially moving interface. It is implied that the flow is similar and the dimensionless stream function is known. Dimensionless mass transfer coefficient can be approximately expressed as a function of a single parameter containing the velocity and the velocity gradient at the interface.
The functional relation is analogous with that by Beek and Bakker and applicable to all similar boundary layer flows. It is also numerically shown that the general correlation gives a good estimate even in the case of small Schmidt number for uniform flow over a flat interface.
