FOAM has been compared with CF

FOAM has been compared with CFX for buoyancy-driven flows a few years ago and as far as I am aware the solution algorithms are very similar and CFX also includes the effect of pressure in density as...

How does he know? You said that all the codes you have are incompressible or is there one in which he could have tried both compressible and...

I am not sure what approximations your Prof would like you to introduce but you have the source code for buoyantFoam and are free to change it in anyway he feels is appropriate.

Could you please...

You could make the assumption

You could make the assumption of incompressibility if it is appropriate for your problem but remember compressibility is not just about the Ma-number, the density could significantly vary due to...

... but buoyancy-driven flows

... but buoyancy-driven flows are compressible; the density changes as a function of temperature and pressure!

'buoyantFoam' is suitable, in

'buoyantFoam' is suitable, in fact it was developed for exactly this kind of flow. Why do you think it is unsuitable? There is also 'buoyantSimpleFoam' for steady-state buoyancy-driven flows.
