What Happens When Cooled Air Passes Over a Vortex Tube?

AI Thread Summary
When cooled air passes over a vortex tube, it is suggested that the cooling effect may enhance the temperature reduction of the cold exhaust rather than destroy the vortex. The discussion highlights the mysterious nature of vortex tubes and the lack of comprehensive theories explaining their operation. Participants express curiosity about the mechanics involved and the potential interactions between the cooled air and the vortex. Engineering insights indicate that the cooling effect could be beneficial. Overall, the conversation emphasizes the need for further exploration and understanding of vortex tube functionality.

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?

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.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
