- Abstract
A combined method for calculating the diffusion for a mixture with an inert gas in which the molar flux of the latter is equal to zero is considered. The method is based on using only one of three Stefan-Maxwell equations, the equation for the inert gas. This equation is reduced to a linear ordinary differential equation of the first order, which has a simple solution. The equations for the inert gas are closed using the modified Fick’s first law. The method makes it possible to radically simplify the study and calculation of multicomponent diffusion. Comparison with the experimental data taken from the literature showed that the deviation of the calculated curves from experimental points for a ternary mixture is within the experimental error.
