Résumé

Two types of gas-dynamic coolers were considered: Rank-Hilsh vortex tubes and resonance tubes, known as devices of Hartmann-Sprenger. These devices have a number of similar physical and structural features: no moving parts, low inertia, environment safety, they can produce cold and heat, generate pressure pulse, and separate gas mixtures. Gas-dynamic devices can be used in the technologies of rare gases obtaining as coolers of reflux condensers. They use pressure drop and don’t need additional energy consumption. The temperature drop of mixtures phase equilibrium allows to reduce the concentration of by-products. Due to this, costs of gas concentrates transportation are reduced. Schemes, in which the separation function of the gas-dynamic devices are used, were investigated. An influence of a scale factor in the interval of the energy separation chamber’s diameter up to 2 mm was studied.
