I'm looking at radiationProperties file in this tutorial: /opt/OpenFOAM/OpenFOAM-v1906/tutorials/heatTransfer/buoyantSimpleFoam/hotRadiationRoomFvDOM
and I am not sure what these values mean: Code:
absorptionEmissionModel constantAbsorptionEmission; constantAbsorptionEmissionCoeffs { absorptivity absorptivity [ m^-1 ] 0.5; emissivity emissivity [ m^-1 ] 0.5; E E [ kg m^-1 s^-3 ] 0; } |

Imagine the hot room to be a sauna filled with water vapour.
Not a sauna person, imagine a hot summer day with high humidity. In either way, the water vapour alters the heat transfer by radiation without scattering. |
