Development of a simulator for ozone/UV reactor based on CFD analysis

摘要

A new CFD (Computational Fluid Dynamics) simulator for an O-3/UV reactor where ozone dissolved water flows under the irradiation of UV, has been developed by combining a fluid dynamics model with a complex radical reaction model. The radical reaction model used in this simulator was found to be (a reasonable, because the results obtained from the simulation of a completely stirred tank reactor (CSTR) system were in good agreement with the experimental results, e.g., the concentrations of total organic CD carbon (TOC), hydrogen peroxide and dissolved ozone obtained from a lab-scale CSTR. Furthermore, by Z using this CFD simulator, the distributions of substances such as hydroxyl radical (OH.) and hydrogen peroxide in the O-3/UV reactor have been investigated. These distributions showed that this CFD simulator was considered to be reasonable. In addition, the simulation results suggested that conventional reactors were not optimized. [References: 4]
