DO radiation
 

Hi all,

I'm new to fluent. I'm modelling a DO radiation process between two surfaces. To define a radiation source, can I just specify a wall type with a fixed temperature? If not, what's the other methods?

Also, in my model, there's fluid between two surfaces. I have to set a fluid type like "air" for it. However, I don't want air to participate in the thermal transfer. How should I delete this fluid type?

Thanks ahead.

How can I define a vacuum volume in fluent? thanks
