Abstract

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 λ_c, a parameter in universal concentration profile, is a function of Sc. Through an empirical approach, it is given as λ_c = 8.55Sc^0.37. With this function, the model matches with experimental data up to Sc = 108.
