Q) How does a Vortex Tube work?

The Vortex Tube is a phenomenon of physics, no one knows exactly why a Vortex Tube works. A description of how the air moves is given below:

Compressed air, normally 80-100 PSIG (5.5 - 6.9 BAR), is injected tangentially through a generator into the vortex spin chamber. At up to 1,000,000 RPM, this air stream revolves toward the hot end where some escapes through the control valve. The remaining air, still spinning, is forced back through the center of this outer vortex. The inner stream gives off kinetic energy in the form of heat to the outer stream and exits the vortex tube as cold air. The outer stream exits the opposite end as hot air.
