Cooling effect of expanding gas problem

Hi everyone!


I was wondering if some of you could give me an idea on how to approach the following problem.

Given 0.24mm OD 0.12 ID steel tube, surrounded by air. Inlet is 2 bar, outlet is 1 bar. I am interested in how to get the rate of cooling in the surrounding air, if only the gas expanding in the tube is used as cooling. Any ideas what settings to use? For the time being, I'm getting temperatures that are in the range of X*10^8 plus lightspeed flow velocities.


Thank You all,
