Abstract
The features of the convective regime that arose due to the instability of mechanical equilibrium of the ternary helium – argon – nitrogen gas mixture during isothermal diffusion were experimentally studied. The influence of the slope angle of the diffusion channel on the intensity of convective flows is considered. The intensity of partial transfer of components in the inclined channel at elevated pressures was measured. A nonlinear dependence of the mixing rate of the components on the angle of inclination was found. It has been established that the observed transfer of components, which is atypical for diffusion, is possible with a certain composition of the gas mixture.
