On species separation in n-component mixture under microgravity
Comptes Rendus. Mécanique, Volume 351 (2023) no. S2, pp. 263-272.

Recently, we proved that it was possible to significantly increase the importance of the species separation for binary mixtures, under microgravity, using forced convection obtained by a uniform translational displacement of the horizontal isothermal walls of the cell maintained at T h and T c respectively, with ΔT=T h -T c .

The present work is an extension of the study performed by Mojtabi (2020) with various mixtures, from binary to n-component mixtures. An application with a ternary mixture was presented. The mixture of tetralin, isobutyl benzene, n-dodecane with respectively 0.8–0.1–0.1 mass fractions was studied experimentally in weightlessness.
