| Popis: | Isothermal multicomponent diffusion in the H2 + Ar–N2 and CH4 + Ar–N2 three-component gas mixtures has been experimentally studied at various pressures and certain concentrations of components in binary mixtures. It has been shown that, in systems where diffusion coefficients differ significantly from each other, convective instability occurs with increasing pressure, which significantly intensifies multicomponent mass transfer. The parameters of transition diffusion mixing to convective can be defined in the framework of stability theory. The comparison carried out between experimental and calculated data shows satisfactory agreement between them. |
