### UV radiation simulation in ANSYS

I am setting up a simulation in fluent to estimate the UV radiation dosage of an air stream passing through a cylindrical duct with the UV source in line with its main axis. It is a very simple system,...

### What is the inuition behind the radiation view factor reciprocity?

I have known that the view factor reciprosity is that Ai x Fij = Aj x Fji But i can't intuitively explain the logic behind this, i do know that the view factor Fij is the portion of the radiation ...
