Dear forumers,
is it possible to specify fixed total radiation wall heat flux using viewfactors radiation model in OpenFOAM? I've looked into the boundary conditions for radiation in the path: Code:
/opt/openfoam211/src/thermophysicalModels/radiationModels/derivedFvPatchFields/ Code:
boundaryField { minX { type greyDiffusiveRadiationViewFactor; value uniform 0; emissivityMode lookup; emissivity uniform 1; Qro uniform 0; } } Any help is appreciated.

Ok, I did my homework and cheked the meaning of Qro inside the class of greyDiffusiveViewFactorFixedValueFvPatchScalarFiel d.H.
So Qro is "external radiative heat flux". Therefore, I think it is not possible to specify total (net) radiative heat flux at wall. Correct me if I'm wrong...
