This paper presents computational fluid dynamics models of UV disinfection systems for water
treatment. Hydraulic, radiation, and dose-response models are used to elucidate important
features, processes, and parameters that impact the simulated performance of UV reactors.
Sensitivity analyses are presented that investigate the impact of different particle tracking models
and parameters. Results show that discrete random walk models can be impacted by system
conditions such as flow rate and model parameters such as the number of particles injected. The
impact of wall reflection on radiative transfer within the reactor is also investigated, and results
show that wall reflection can significantly increase the simulated dose in water with high UV
transmittance. Evaluation of different pipe configurations and their impact on the simulated
approach hydraulics and system performance is also investigated. Includes 4 references, tables, figures.
