Hi Foamers!

I have been using interFoam to do simulation of incompressible two-phase flow and had a little bit experience on OpenFOAM source code developing.

Recently I am considering work on compressible fluid (refrigerant) inside air conditioner or refrigerator. Since I have no experience on how OpenFOAM does with compressible fluid I need your help!
To briefly describe refrigerant fluid characteristic:
1. Compressible, pressure, temperature and velocity should all be coupled by the ideal gas equation.
2. Should be subsonic. In fact I think velocity should be safely under 1m/s.

I googled for a while and notice there are several so called density-based compressible fluid solver provided by openfoam but have no idea which one is better for me to get start, or just should create one from scratch?

Plz leave your comment or advice!
Thx!
