this is a comment, but thoughts are welcome.

I realize ideal gas with "total energy" is the easiest way to model compressibility effects in high speed flow in CFX (im using v15), but i am surprised it also accounts for Joule Thompson (JT) cooling - which i observed flow flow in a pipe. Indeed it was similar to OLGA JT cooling (a 1D pipe simulator).

In hindsight maybe that is to be expected, even though an ideal gas is being used, it is still compressible, so JT cooling is still allowed for. Initially I thought a real gas would be required to see JT cooling in CFX

JT cooling is simply the cooling effect associated with the expansion of a compressible gas. An ideal gas is compressible so can show the effect, so can a real gas. Why is this surprising?
