Quasi 3D Modeling Flow and Contaminant Transport in Shallow Waters --- Using Multiple Depth-Averaged Two-Equation Closure Turbulence Models, CFD Software

0

The ‘standard’ two-equation turbulence models, used widely in industry, cannot be directly used in depth-averaged modeling. Till now, the vast majority of quasi 3D numerical tools just can provide one depth-averaged 2-eq. k-ε model for modeling side-charge problem on single-level grid. Due to the absence of one ‘universal’ model in the turbulence modeling theory, this book, therefore, introduces other two depth-averaged 2-eq. turbulence k-w and k-ω models, built by the author; describes the development of Q3drm1.0 software, and provides 8 examples of steady/unsteady flows and transports, caused respectively by side-discharge, point-source and area-source discharges for The Yellow River, Mississippi River, Yangtze River, Amazon River and so on. The software can simulate and analyze flows/transport behaviors by using 3 depth-averaged 2-eq. models. This book should be especially useful to researches and professionals in water science, engineering, environment and IT fields.

Quasi 3D Modeling Flow and Contaminant Transport in Shallow Waters

Using Multiple Depth-Averaged Two-Equation Closure Turbulence Models, CFD Software Development and Applications

It is well known that the ‘standard’ two-equation 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 just can provide the only one depth-averaged two-equation closure turbulence k-ε model for modeling side-discharge problem on single-level grid. Due to the absence of one ‘universal’ turbulence model in the turbulence modeling theory, this book, therefore, introduces other two depth-averaged two-equation closure turbulence k-w and k-ω models, established by the author; describes the development of a CFD (Computational Fluid Dynamics) software, namely Q3drm1.0 (Quasi 3D refinedly modeling), including its grid-generators, flow-solvers and 2D/3D visualizations; and provides eight computational examples of steady/unsteady flows and transports, caused respectively by side-discharge, point-source discharge and area-source discharge, on non-orthogonal body-fitted multi-grids, for The Yellow River, The Mississippi River, The Yangtze River, The Amazon River and other natural and artificial waters. The software can simulate, predict and analyze environmental flows and transport behaviors by using the three depth-averaged two-equation closure turbulence models. This book should be especially useful to researches and professionals in water science, engineering, environment and IT fields. (English, 260 pages, 357 figures and 8 computational examples)
