Quasi 3D Modeling Flow and Contaminant Transport in Shallow Waters

Modeling flows and transports in shallow water is big challenge, as the bad effect of pollutant discharges on our limited water resources. The standard 2-eq. closure turbulence models, used widely in industry, cannot be directly used in depth-averaged modeling. Till now, the vast majority of quasi 3D numerical tools only can provide unique k- model for modeling on single-level grid. Due to the absence of universal turbulence model, this book, therefore, introduces other two depth-averaged turbulence models: k-w and k- , developed by the author; describes a CFD software development: grid-generators, flow-solvers and 2D/3D visualizations of results; and provides 8 computational examples of steady/unsteady flows and transports, caused by side-discharge, point-source discharge and area-source discharges, on non-orthogonal body-fitted multi-grids, for The Yellow River, The Mississippi River, The Yangtze River, The Amazon River and other waters. The software can simulate and analyze flows and transport behaviors by using three depth-averaged 2-eq. closure models. This book should be especially useful to professionals in water science and engineering, environment and IT fields.
