Abstract

A direct numerical simulation of the Ranque-Hilsch effect in a counterflow vortex tube with a diameter of the hot air diaphragm coinciding with the diameter of the tube was performed. We used DNS-modeling on the basis of the large-particle method in a cylindrical coordinate system, which allows us to take into account the scale of large turbulent vortices. An analysis of the energy distribution in the system under consideration gave a picture of the temperature distribution in the volume of the vortex tube.
