Numerical simulation methods are used to study quasi-stationary mixing in binary mixtures when the density heavier gas is located in the upper part of the diffusion channel, and the second one is in the lower part. The slope angles, at which the regime changes from diffusion to concentration gravitational convection, are determined. The dynamics of structured convective flows at various angles of inclination is analyzed. The dependence of the intensity of convective flows on the slope angle of the diffusion channel for a binary mixture 0.15 Ar + 0.85 N2 - N2 is obtained.
