Hi foamers,

I was wondering if I had to use a multiphase flow solver like multiphaseEulerFoam in order to handle two different inlets with two gases although two gases are just making one single physical phase ?

To be more precise :
In fact I have two inlets on something which looks like a pipe.
One gas for each inlet.
The two gases have their own properties (pressure, temperature...).

I would like to simulate a compressible and turbulent flow (with a RASmodel) but I don't know which solver is able to handle that.
A "simple" compressible flow solver (like rhoPimpleFoam) or a multiphase flow solver (like multiphaseEulerFoam) ?

No idea ? Because I really don't know which OpenFOAM example to follow in order to start my case... It seems that there isn't any case like that...

Apparently I was completely on the wrong way.

I've found hints there:

reactingFoam should do the job for mixing gases even if there is no reaction.

Have a nice project,
Adrien
