Calculation of heat transfer in Ranque–Hilcsh's vortex tube

This paper describes problems of calculation of hydrodynamics and heat transfer in vortex tube for International Journal for Numerical Methods in Fluids. The Ranque effect has been known since 1931. The existence of the effect is proved by multiple experiments, but there is no strict physical explanation of the effect and there are more than ten hypotheses. Our calculations show that there is no need to use any additional hypothesis to explain the effect, but it is necessary to solve the difficult problem of hydrodynamics of compressible gas in complex geometry.
