Hilsch Tubes Revisited
"PrecisionmachinisT" fired this volley in

When it comes down to it, despite the claims of the various vendors, I
really do have serious doubts that any more heat is carried away from
the workpiece by using the cold air out of a vortex tube than would be
carried away by simply using the same amout of total of mass air flow
that would have been output into a standard air nozzle at room temp
directly from the compressor instead.
I'll make the lesson real simple, TMT.
Take a workpiece at 100 degrees.
Pour 100 degree air over it.
How much heat do you remove from the workpiece? Zero.
Reduce the temperature of the air (any amount, but say) to zero degrees.
Pour that air over the workpiece.
Now you answer the question, TMT -- Is any heat removed from the
workpiece?
Now, extrapolate that to other relative temperatures...
I'd love to read your conclusion.
