This article, along with hundreds of other projects, can be found on The Amateur Scientist CD-ROM. An expanded version of this article can be found in The Scientific American Book of Projects for the Amateur Scientist by Clair L. Stong. Tim Cockerill's thesis was an investigation into the theory of the Ranque-Hilsch Vortex Tubes. EXAIR is a commercial supplier of Ranque-Hilsch Vortex Tubes. Their site contains an animated demo showing how the tube works. An Experimental Performance Evaluation of Vortex Tube is a paper that was presented to The Institution of Engineers (India). The Vortex Technologies page, on Jean-Louis Naudin's site, contains some interesting vortex effects from "The Far Side".
