Dear CFD members.
Hi, I`m ryun. When I solve radiation problem using DO model,
there are some trouble with my FLUENT solving.
So Can you help me about this??
I want to set the absorptivity of the wall of 0.9 and simultaneously to
set the emissivity of 0.1, making called "optical coating" condition.
But as I know in my short knowledge, FLEUNT assumes that emissivity and
absorptivity is same.
moreover, I can`t find any blank to fill the absorptivity.
So I'm glad you to let me know how to set the absorptivity of
the wall condition differ from emissivity.
PS : absoption coefficient isn`t considered in this matter.
