Simulating temperature increase due to compressing gas

[RoSChneider]

Guys,

We all know that when compressing a gas the temperature increases (good old bicycle pump experience). Offering compressible flow analysis without considering this effect (the present status in Simulation CFD) restricts the usefullness of Simulation CFD in many applications. Example: Designing a pressure safety valve so that the temperature in the release channel remains below the material temp limits (i.e. temp at which rubber of plastic seals burn or melt).

There are a number of engineers out here who have to revert to optimizing the design using another simulation tool, reducing the acceptance of Simulation CFD. Adding temperature effects to the Simulation CFD compressible flow solver would greatly enmhance acceptance!

Haben wir schon vor Jahren angeregt, doch passiert ist leider (noch) nichts .....drücke mal die Daumen das dies auch viele Andere gebrauchen können.

We had the same problem with the study of a void sliding vane compressor.

It would be nice to be able to simulate it at least in 2d.

Would be applicable to the whole world of rotating machines like fans and so on!
