reactingFoam's source term: rho*g
 
Hello guys,

I found this rho*g term in reactingFoam is handled in UEqn. This is not common in OpenFOAM buoyant driving/multi-phase solver.

Im wondering the reason of this. I mean put rho*g in Ueqn in reactingFoam instead of putting it in the pressure equation.

Best,

I have the same problem here, is there someone who would like to shed some light on it?

In my opinion, puting rho*g in Ueqn in reactingFoam is somewhat similar to the Boussinesq approximation.
