However, I am not clear about radiation model usage. If I need to account radiative heat transfer for cooling effect in my model, as my wire heated by joule heat that i assign in cell zone, do i still need to use one of radiation model to do radiative heat transfer for cooling my wire to ambient?
As I'm read in ANSYS help and heat transfer book, in mu understanding, by using radiation model it will account the radiative heat transfer. If not, the radiative heat transfer is not account in our case. Please correct me if I'm wrong.
I hope you or anyone else can share the opinion regarding this.
