INSTABILITY OF MECHANICAL EQUILIBRIUM OF BINARY MIXTURE Ar-N2 IN WEAKLY UNHOMOGENDOUS TEMPERATURE FIELD AT DIFFERENT VALUES OF PRESSURE

Abstract

We have experimentally studied the boundary of transition “non-isothermal diffusion – gravitational convection” at different values of pressure in unhomogendous temperature field. We have shown that at some value of pressure the changing of regimes “non-isothermic diffusion – concentration gravitational convection” is occures. Results of the experiment are corresponding to theoretical results obtained via stability theory.
