Hi,
I’m simulating radiation from a rough surface using Fluent. So, is there a relationship between surface roughness and the emissivity in Fluent? |

In Fluent, no. The surface roughness is purely for the hydrodynamic effects.
You can still model radiation from a rough surfaces if you know what the correct emissivity is for your rough surface, but the surface roughness input is for something else. |
