Abstract:
Instability of mechanical equilibrium in isothermal binary gas mixtures is studied in experiments with different angles of inclination of the diffusion channel with respect to the vertical axis. As the angle of inclination is increased, the intensity of convective mass transfer is found to decrease and decay at a certain value of this angle. Experimental data are demonstrated to be consistent with estimates obtained from the linear stability theory. © 2010 MAIK/Nauka.
