Summary

The heating and cooling in a vortex tube is attributed to conversion of kinetic energy into heat and to the reverse process. A two-component model yields the upper limit for the temperature increase on the hot side. Extensive experimental data for a vortex tube of 18 mm inner diameter with working fluid air all fall between these limits. The model predicts when the inlet velocity reaches the speed of sound; values obtained in these experiments indicate that the flow always remain subsonic.
