Multicomponent mass transfer in turbulent flow

Abstract

This paper analyses steady-state mass transfer between a wall, or interface, and a turbulently flowing fluid phase. The system is assumed to be multicomponent (number of species n̲2) and proper account is taken of the diffusional coupling between the species transfers. The analysis results in a generalized procedure for the calculation of the elements of the matrix of multicomponent mass transfer coefficients from in information on the eddy diffusivity in the boundary layer region, together with other physical and flow parameters. Appropriate correction factors to take account of high transfer rates have been defined and explicit expressions derived for these. Various special cases (small transfer rates, binary mass transfer, multicomponent Reynolds analogy) have been pointed out.
