Keywords:

convection; diffusion; gases with equal molar masses; instability of mechanical equilibrium


Abstracts:

The mixing process of binary mixtures of propane and nitrogen with carbon dioxide and propane and carbon dioxide with nitrogen is studied by the two flask method. The regimes of mixing and the transition boundaries from the molecular diffusion to the concentration convection are defined at the various pressures.
