An Investigation on the Effect of the Hot End Plugs on the Efficiency of the Ranque-Hilsch Vortex Tube

Abstract

The phenomenon of temperature distribution in confined steady rotating gas flows is called as Ranque-Hilsch effect. The simple counter-flow vortex tube consists of a long hollow cylinder with tangential nozzles at one end for injecting compressed air. Rotating air escapes the tube through two different outlets-a central orifice diaphragm placed near the inlet (cold end) and a ring-shaped peripheral outlet at the opposite end of the tube (hot end).
