Also, Could the process be used to cool the gas if the Controlled Valve was replaced with a pump and swap the direction of the one way valve? The steps would be the reverse of State 3. Then pump the gas from the right to the left. Is that correct?

Also, does this thing I have “created” have a name?

    This is leaving out that this only works with air (and many other gases) at room temperature, but neither all gases nor at every temperature. The Joule Thomson effect, or rather the Joule–Thomson coefficient, is not always positive.

    Temperature at step 2 will not be T0 for any real gas.

    In other words: This is a purely theoretical thing assuming ideal gas. It is still useful to understand the concept of work here.

      Thanks, I am trying to build a toy simulator and I don’t know much about this stuff. I have been reading Wikipedia, so I have conceptual gaps.

      Is the Joule Thomson effect related to converting internal energy to the kinetic energy of the gas. If so, shouldn’t the temperature return once the flow stops?
