Computational Fluid Dynamics:Optimizing Water Quality in Clearwells, Tanks,and Distribution Storage Reservoirs

摘要

A computational fluid dynamics (CFD) model has been applied to the study of flow within several hydraulic structures and water treatment facilities. In particular, the model has been successfully applied to the hydraulic design of clearwells, especially for optimizing chlorine contact times. The model has also been applied to optimize water quality by improving disinfectant residual in water storage reservoirs. In some of the applications, the model was favorably compared to measured experimental and field data. Currently, the model is being used in lieu of experimental testing for the hydraulic optimization of various hydraulic structures including clearwells, storage reservoirs, and pump wetwells. Due to limited space requirements, this paper addresses the application of the model to one clearwell in Palmdale, California. At the symposium, additional examples will be provided.
