Yu, L: Quasi 3D Modeling Flow and Contaminant Transport in S

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-e 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.
