Surface integrals report: incident radiation
I want to model radiation through a lamp, which is placed inside a cylinder parallel to the longitudinal axis of the cylinder. I have defined the Irradiance on the lamp surface for example 300(W/mē) in the Discrete Ordinates(DO) model. After running several iterations; when i have checked the incident radiation on the lamp surface(Report->SurfaceIntegrals->Areaweighted ave->Incidentradiation), its showng a different value (for ex. 400 W/mē). Can anyone pls explain me what does it mean by Incident radiation in FLUENT. And what is wrong in my case.
thanks in advance
