Surfacing in ReactingFoam

Sergey_aero · April 23, 2024, 13:58

Hello everyone I'm new to OpenFOAM. I want to simulate the combustion of an axisymmetric burner. Gorenje. But rhoReactingFoam does not model convection. There is only pseudo-density phi in this dictionary. If I understood correctly, then you can't simulate convection in RectingFoam either. Convection is the ascent of warm air. I'm sorry for the bad language

it would be useful to try bouyantReactingFoam (early fireFoam). It deals all processes that take place during fire.

Hey,

I believe you can use fvOptions to add a buoyancyForce to your simulation with reactingFoam. It should enable buoyancy effects.
