DO radiation model

jarno brunetti

I have three questions about DO radiation model. In my case the radiation emitted by flame arrives on a surface which has a 0.3 emissivity coefficient; some of this radiation sholud be reflected by surface itself. 1- Does the power radiation arriving on the surface correspond to "radiation incident" in "display contour" window or in "report--> Surface integral" window? 2- Does Fluent consider the fact that the reflected radiation is absorbed by the fluid and by other surfaces? 3- Defining "heat flux 0" for a Wall Boundary, what happens to radiation incident on this surface? Thank you in advance Jarno
