Hello,

I am trying to model a part in a closed furnace that is being heated strictly through radiation on the end faces from the furnace. I set a temperature BC on the furnace to be 1200 C. For this model, the furnace is not enclosed, the ends of the furnace are open. I was wondering what the effect of ambient temperature is on radiation in an open cavity? How does a high/low VTOL affect the radiation? Is it possible to simulate a closed cavity radiation even while the cavity is technically open (vacuum conditions with no convection)?
