要約
This paper considers the numerical modeling of convective diffusion in three-component gas mixtures. The experimental results on the study of unstable diffusion process at different pressures is carried out based on the numerical solution of unsteady filtered Navier-Stokes equation, the continuity equation and equation for the concentration. Comparison of the results of numerical simulations with experimental data for the system 0.4688 He + 0.5312 Ar - N2 showed that the intensity of convective mass transfer increases at a certain critical value of pressure.
