Hello Abose,
PMMA is non-charring process right ?
PMMA --> GAS
PMMA undergoes both pyrolysis and thermal oxidation ? If then (if only solid), no need to merge with fluid part.
In fireFoam-dev ☞...

Hello Alexis,

1. Hope you made 3 pyrolysis regions using the following commands:
blockMesh >> topoSet >> splitMeshRegions -cellZones -overwrite

Points 2-6 are bit confusing unless I...

Your case is somewhere similar to biomassgasification solver and its possible to implement in OpenFOAM.
Firstly, I hope you have created 3 pyrolysis solid regions in OF, which is very...

Hello Armin,
Yes you are right here. Since you worked with VOF model, you might have better exposure to work with multiphase flow. With this move ahead, learn OpenFoam techniques then and there, you...

Hi,
As per your explanation above, you have just one domain/region. Fluid/solid interaction takes place inside one domain. In your case, the source of energy is from fluid, thereby pyrolysing the...

Hello Armin,
The energy in the form of heat is supplied by hot molten metal in fluid state. This source of energy from fluid causes the solid polymer to pyrolise. Its perfect fluid/solid...

Hello Armin,
You are welcome. It depends on your work. In my work, 2 regions are solid, in one region I need to solve only diffusion equ, whereas the other region solves pyrolysis. By switching...

Hello Armin,

Yes you are right. FireFOAM solver rely on pyrolysis based on the keyword pyrolysis.evolve(). It was resolved based on regionModel (based on coupled Boundary condition -...
