Does the wallHeatFlux utility include radiation?.

I've been looking at a heated body in a still room (basically a modification of the hotRadiationRoom tutorial) using both the buoyantSimpleFoam and buoyantSimpleradiationFoam solvers.
The total heat transfer from the body, as reported by wallHeatFlux is very similar for both solvers. However my back of the envelope calculations suggest there should be about 50%-75% difference for my case.


If the wallHeatFlux utility doesn't include radiation, is there a simple way of extracting the total heat transfer due to radiation for a given surface?

The default version did not calculate radiation. Search the form to find a fixed version.

Thank you - but do you have a link to the fixed version?. I've searched through the forum but can't seem to find anything relevant.

Hi Foarmers,

I have the same problem.Is there the wallHeatFlux utility that include radiation heat flux?( I use buoyantBuossinesqSimpleFoam solver with radiation)

best regards
