Can a Vortex Tube Be Reversed to Generate Compressed Air?

Click For Summary
SUMMARY

The discussion centers on the feasibility of reversing a vortex tube to generate compressed air by introducing hot and cold air into the opposing sides, typically designated for gas output. Participants assert that while it is theoretically possible to manipulate gas flow from low pressure to high pressure, significant energy waste would occur in this process. The consensus indicates that using a vortex tube in reverse does not yield efficient results for compressed air generation.

If atmospheric pressure hot and cold air are sent into the opposing sides of a vortex tube (the ports normally used for gas outlet), will compressed air be generated/released from the hole/port normally used for gas input?

The reverse of the system above (cold and hot air enter from opposing ends and compressed air is sent out).

"Strictly?" "Trick" a gas into flowing from low-P to high-P by mixing hot and cold streams? Not without significant waste.
