Problem DO Intensity
 

Hello,

I am simulating light intensity distribution from a UV Lamp in a Photocatalytic reactor that contains a photocatalytic media and I am having trouble.

Based on several literature read the UV lamp is defined as a hollow cylinder and modelled as a semi-transparent with diffuse radiation of at XW/m2 . My problem is that I input this X value in my case 120W/m2 but when I look at the DO Irradiation on the lamp in post I always have a value much much higher than what I inputed. I do not know what I am doing wrong.


Can anyone please please please help me out.

Thank you in advance.
