Computational fluid dynamics modeling (CFD) is a tool that has been shown to successfully determine relative differences in ultraviolet (UV) reactor performance. This paper presents a comparison of CFD modeling coupled with a UV intensity model to reproduce validation tests for several UV reactors. This study demonstrated that a hydraulic grid independent solution could be achieved. At lower UVT the modeling approach predicts the dose fairly well; however, there is deviation in the results at higher UVT. Includes 4 references, tables, figures.
