What was computed

254 nm is used mainly for disinfection, while 185 nm breaks water molecule (H₂O) bonds to generate hydroxyl radicals (•OH) for photochemical reactions (e.g. UPW oxidation processes). We computed the fluence rate distribution at both wavelengths for an actual reactor geometry with a 24-lamp array.

185nm — the wavelength band involved in photochemical reactions (radical generation)

254nm — the wavelength band mainly responsible for disinfection. Fluence rate rises sharply in the high lamp-density center

Public experimental data at 185 nm is scarce, due to the health hazards and high cost of such measurements, so a quantitative comparison against literature is not feasible here. Treat this document not as validation, but as an example of UVSim3D's calculation capability for a multi-wavelength, multi-lamp reactor geometry.
