Hello I have two different models that I want to simulate including radiation effects.

1- A plate that it "floating" on air, the plate has internal heat generation amd it is cooled by natural circulation of air and radiation to the ambient. Wall temperatures around 700K are expected with an ambient air temperature of 300 K.

2- Similar as above but there are an arrange of pararel plates inside a housing, so the plates and the housing transfer heat trhough radiation, conduction and convection and the housing dissipates trhough radiation to the ambient. Similar temperatures are expected.

I have no problem with conduction and convection but it is my first time with radiation.

Should I use the same radiation model for both cases? S2S is suitable for to-ambient radiation? how?

Thank you

If you check the User's Guide (possibly Theory) it'll explain the model limitations. Assuming there's no absorption in the fluid phase then S2S is good, otherwise there's the DO model. Monte Carlo was added a few releases back, and should be suitable too: I've not used it yet!
