Hi
I work on natural convection in inclined channel.
when i have stimulated the pur natural convection, a good results are obtained, but when i use the DO model to test the effect of surface radiation, the results are bad (illogical). i don't understand where is the problem. the radiation properties of the air (absorption and scattering coefficient) equal to zero, but n=1. can you help me please.
thanks

Dear Dalia...

Check the box to react DO/Energy coupling

This will give satisfactory convergence and data inshaallah
