Can a Vortex Tube Be Reversed to Generate Compressed Air?

[ejnovek]

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).

compressed air be generated/released from the hole/port normally used for gas input?

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