What Happens When Cooled Air Passes Over a Vortex Tube?

Click For Summary
SUMMARY

The discussion centers on the effects of cooled air passing over a Ranque-Hilsch vortex tube. Participants conclude that introducing cooled air does not destroy the vortex but rather enhances the cooling effect of the cold exhaust. The mechanics of vortex tubes, which separate hot and cold air streams through centrifugal force, support this theory. Understanding these principles is essential for optimizing the performance of vortex tubes in various applications.

PREREQUISITES
  • Understanding of thermodynamics principles

To anyone familiar with the Ranque-Hilsch vortex tube:

Say if the cooled air is allowed to pass over the vortex section of this tube, what would happen?

Would the effect of cooling be the destruction of the vortex? or would it act to further decrease the temperature of the cold exhaust?
 
Science news on Phys.org
My engineering sense tells me that it would just aid in cooling. However, I don't know how vortex tubes actually work nor have I seen a sound theory that can explain them. They are very mysterious devices.

BTW, welcome to the forum.
