Experimental verification of the Stefan-Maxwell equations

Analysis of the study by Carty and Schrodt is performed, and it is shown that the experimental data of the authors are in satisfactory agreement with the data calculated by the Stefan-Maxwell equations on the basis of an actual length of the diffusion channel. Equations for profiles of the concentrations of components in the diffusion channel are derived. The dynamics of steady-state evaporation of acetone and methanol into air at a temperature of 35°C is experimentally studied, and a satisfactory agreement is found between the values of fluxes measured in experiments and calculated by the Gilliland equations that are the solution of the Stefan-Maxwell equations for a ternary gas mixture.
