Discrete ordinate model

how to calculate absorption coefficient and scattering coefficient of absorber (aluminium plate) and air in discrete ordinate radiation model for solar air heater?

It'll depend on the surface finish etc, so is something you need to assign to the surface.

I have a big problem, I retried many times to solve since a month, I define Do model for UV lamp radiation field simulation, my question,, 500 W/m2 diffused radiation is defined at lamp wall while in result I get radiation intensity 860 W/m2 which is more than what I defined at the source wall, no reflection defined or other sources.
