Hello everyone,

I can imagine this is an interesting topic for many people...

in my Bachelor thesis I have to simulate the combustion of certain particles (surrogate fuels, meaning garbage particles).

Now, I decided to use fireFoam as a solver, but have no idea how to include particles. I was able to simulate CH4 combustion as a gas, but how on earth is it possible to include particles?

I did the "simplifiedSiwek" tutorial for coalChemistryFoam. I got this to run, but am not able to use the burner I need. It couldn't find the "parcel injector cell" when I use the burner I need for the thesis instead of the burner of the tutorial case.


Can anyone please give me any tips? Did anyone simulate burning particles or know how to do it? If not fireFoam, what solver would you recommend?


Thanks a lot in advance,
Toby

Hello again,
this topic might get a little more interesting if I write what I've done so far

To include particle combustion I tried to compile my own Solver. To do so I did the steps of this tutorial (page 20 following). Instead of combining solidParticle and simpleFoam I combined solidParticle and fireFoam.

After a while I was able to compile the stuff. Unfortunately following error occurs when I try to work with the solver now:

Could anyone please tell me what I did wrong?
I would much appreciate any reply...
