Flow and thermodynamic characteristics of energy separation in a double-circuit vortex tube - An experimental investigation

Experimental investigations were made into the vortex energy separation effect of gas flux in tubes known as the Ranque effect. Technical applications of the results are considered. Unlike traditional energy separation tubes, so-called double-circuit vortex tubes were chosen that allowed the creation of a refrigeration device with high thermodynamic efficiency. Different thermodynamic and gas dynamical aspects of the processes taking place in the scheme developed are discussed taking into account the modern vortex interaction hypothesis. The possibility of constructing a double-circuit vortex tube refrigeration machine as efficient as a gas expansion system is demonstrated.
