Transmissivity for surface-to-surface radiation

pss47 · January 31, 2019, 11:01

Hello all,
I am using Openfoam 6 for Vehicle interior simulation. I want to implement surface-to-surface radiation heat transfer without participating medium. I found out that view factor model is suitable for the case with "greyDiffusiveRadiationViewFactor" for specifying emissivity value for each surface.

But I cannot specify transmissivity value for semi transparent surfaces. Is there any boundary condition or radiation model to specify both emissivity and transmissivity for surface radiation?

Thank you

Please anyone?
