Maxwell's demon in the Ranque-Hilsch vortex tube.

Phys Rev Lett

Department of Applied Physics, Eindhoven University of Technology, Netherlands.

Published: August 2012

A theory was developed that explains energy separation in a vortex tube, known as one of the Maxwellian demons. It appears that there is a unique relation between the pressures in the exits of the vortex tube and its temperatures. Experimental results show that the computed and measured temperatures are in very good agreement.
