Thermal Imaging Study of Turbulent Structures at the Outlets of a Vortex Tube

A device is presented that has a temperature converter made in the form of a mesh made of a material with low thermal conductivity and a thermal imager. Its use makes it possible to record the air-flow temperature field layer by layer, which indirectly determines the configuration and dimensions of the vortex structures at the outlets of the vortex tube. It has been established that the parameters and structure of the outgoing flows of both cooled and heated air from a counterflow vortex tube with axial outlets depend on the ratio of the areas of the flow sections of the diaphragm and diffuser.
