A simple model for turbulent boundary layer mass transfer on flat plate in parallel flow

A simple model for turbulent mass transfer from a flat plate valid for wider range of Schmidt numbers is proposed. Based on 1/n power law velocity/concentration profiles and integral momentum/mass equations, the model reveals that X,, a parameter in universal concentration profile, is a function of Sc. Through an empirical approach, it is given as lambda(c) = 8.55 Sc-0.37. With this function, the model matches with experimental data up to Sc = 108. (C) 2002 Elsevier Science B.V. All rights reserved.
