Hi all,

Does anybody know how temperature is handled in rhoSimpleFoam? I have a semi-complicated simulation that runs really well and I am getting great results for pressure and velocity but the temperature profile seems quite wrong. From the rhoSimpleFoam.C files I couldn't figure if enthalpy is taking care of temperature.

Basically, this might be stupid but I have no clue how temperature is solved for in rhoSimpleFoam or a simple loop in OF. Can somebody give me some insights?

Thanks a million,
~Ammar.

Hello!

I am facing the same problem. I try to simulate a radial compressor with pressure ratio about 2. I can not see any temperature rise. This behaviour is unphysical. OF2.3.
Does anyone have a hint?

Regards, JCW

hello,
take a look at http://cfd.direct/openfoam/energy-equation/
... and also the source file EEqn.H for rhoSimpleFoam.

what did you use in you thermophysicalProperties ? enthalpy or internal energy ?

regards,
olivier
