Hello everyone,

After working on my problem of a fluid passing in a channel of square section where I took account of convection and conduction, I would like to add the radiation.

The model I chose is FVDom since my fluid radiates just like the walls.

My problem is with the validation of the results. When I try to make a manual approximation I never arrive at the same order.

I think my problem comes from the inlet and the outlet. I have searched extensively on the forum but I have not found anything about it and this is the reason for my post.

How OF considers inlets and outlets in the radiation model? black body? opaque?

I tried to define them differently in the Idefault file but nothing has changed in the results ...

Would anyone have the answer to my problem?

Thank you in advance.
