Features of diffusion and convective mixing in mixtures containing hydrocarbons

Abstract

Abstract Diffusion mixing in mixtures of C3H8 + CO2 - N2O, Ne + C3H8 - N2O + C3H8, N2O + He - C3H8 + CH4 at different pressures has been studied experimentally. It has been found that at a certain pressure in the mixture there are convective flows distorting the expected diffusion transfer. The transition parameters from diffusion to convective mixing type can be determined in terms of stability theory. The numerical results are compared with experimental data.
