NUMERICAL ANALYSIS OF TERNARY MASS TRANSFER IN A LAMINAR BOUNDARY LAYER

[摘要] References(17)Cited-By(7)Numerical approaches to ternary mass transfer in a laminar boundary layer were made by use of a laminar boundary layer theory considering the effects of interactions between diffusion fluxes and of mass injection or suction. The effects of both the driving force ratios and the imilticomponent Schmidt numbers on the concentration profiles and the diffusion fluxes are discussed. A new correlation is proposed for the effect of the interactions between the diffusion fluxes under the condition of low mass flux and of zero tangential surface velocity, which is a function of the driving force ratios and the multicomponent Schmidt numbers. The possibih''ty of a reverse diffusion was also shown under the same condition. Some examples of numerical analysis are presented for the effect of mass injection or suction and of the tangential surface velocity on the diffusion fluxes.
