Numerical simulation of the concentration convection that occurs in a three-component gas mixture He + Ar – N2 in an inclined channel has been carried out. To describe the occurrence of convective flows in the mixture under consideration, a 3D numerical algorithm based on the D3Q19 model of the Boltzmann lattice equation method has been developed. It is shown that when the slope angle changes in the range from 40° to 80°, the isoconcentration lines are curved, which indicates the presence of convective mechanisms in the total mass transfer. It is shown that at an inclination angle of 60°, the intensity of convective transfer is maximum.
