Hi all,
I'm running a fireFoam simulation with propane as the fuel. All going well so far. I was wondering: 1) How do I model smoke? 2) what do the I_Lambda fields mean? 3) any thoughts on sootModels? I'm just exploring this now. Brett |

Attempting to briefly answer the questions :
1 : To answer with a question, do you mean soot modeling? If so, check out the smallPoolFire2D tutorial. Also, this chalmers student report : http://www.tfd.chalmers.se/~hani/kur...sh_revised.pdf. 2 : They are used for fvDOM radiation modeling. 3 : Soot modeling is incredibly complex, and the model that exists with the release is very simple. There is a wealth of literature on soot modeling, and quite a few on soot models in OF (e.g. https://www.researchgate.net/publica...using_OpenFOAM). Caelan |

Thanks heaps for the response.
Indeed I think I do, essentially soot = smoke ? that makes me sound so stupid.... I'm working with just the basics for now, I'll be theres heaps of literature and many different methods. Thanks for the reference too. |

soorry just to check.
so the I_Lambda are what? different radiation frequencies? |

If I remember correctly, radiations "rays" used for the discrete ordinate method. I'm sure there is literature floating round on it (there's even a wiki page : https://en.wikipedia.org/wiki/Discrete_ordinates_method).
