Multiphase Flow and Transport Processes in the Subsurface available in PDF, EPUB and Kindle. The general formulation of a model is an important precondition for modeling multiphase flow and transport processes in subsurface hydrosystems. This book presents a consistent and easily accessible formulation of the fundamental phenomena and concepts, a uniform description of mathematical and numerical modeling, and latest developments in the field of simulation of multiphase processes, especially in porous and heterogeneous media. The author discusses in detail not only general aspects of the selection of relevant processes and corresponding parameters but also the mathematical and numerical modeling concepts.

Multiphase Flow and Transport in the Subsurface available in PDF, EPUB and Kindle. (from the 1st edition) One important precondition for modeling multiphase flow and transport processes in the hydrosystem "subsurface" is the general formulation of a model. The objective of this book is to present a consistent, easily accessible formulation of the fundamental phenomena and concepts, to give a uniform description of mathematical and numerical modeling, and to show the latest developments in the field of simulation of multiphase processes, especially in porous and heterogeneous media. Some general aspects which affect the selection of the relevant processes and the corresponding parameters as well as the mathematical and numerical model concepts are discussed in detail.

In order to protect groundwater resources from pollution and to clean up contaminated sites, we should understand the fate and transport of contaminants in the subsurface and physical-chemical-biological processes involving remediation. To enhance our understanding, numerical studies are performed on (i) multiphase flow and multispecies transport of volatile organic compounds (VOCs), (ii) biological transformations of contaminants, (iii) in-situ air sparging (IAS), and (iv) thermal enhanced venting in the subsurface. Among VOCs, trichloroethylene, dichloroethylenes, and vinyl chloride are chosen as target contaminants herein. The effects of density-driven advection of gas phase and biotransformation of contaminants on their fate and transport are analyzed under various environmental conditions involving infiltration, permeability, and bioreaction kinetics. Under IAS, the interactive dynamic flows of water and injected air through porous media in the subsurface are elucidated. A three-dimensional numerical model, called TechFlowMP, is developed, verified, and validated using analytical solutions and experimental data published in the literature.

This book was released on 2007. Subsurface Multiphase Flow and Multicomponent Reactive Transport Modeling Using High-Performance Computing available in PDF, EPUB and Kindle. Numerical modeling has become a critical tool to the Department of Energy for evaluating the environmental impact of alternative energy sources and remediation strategies for legacy waste sites. Unfortunately, the physical and chemical complexity of many sites overwhelms the capabilities of even most "state of the art" groundwater models. Of particular concern are the representation of highly-heterogeneous stratified rock/soil layers in the subsurface and the biological and geochemical interactions of chemical species within multiple fluid phases. Clearly, there is a need for higher-resolution modeling (i.e. more spatial, temporal, and chemical degrees of freedom) and increasingly mechanistic descriptions of subsurface physicochemical processes. We present research being performed in the development of PFLOTRAN, a parallel multiphase flow and multicomponent reactive transport model. Written in Fortran90, PFLOTRAN is founded upon PETSc data structures and solvers and has exhibited impressive strong scalability on up to 4000 processors on the ORNL Cray XT3. We are employing PFLOTRAN in the simulation of uranium transport at the Hanford 300 Area, a contaminated site of major concern to the Department of Energy, the State of Washington, and other government agencies where overly-simplistic historical modeling erroneously predicted decade removal times for uranium by ambient groundwater flow. By leveraging the billions of degrees of freedom available through high-performance computation using tens of thousands of processors, we can better characterize the release of uranium into groundwater and its subsequent transport to the Columbia River, and thereby better understand and evaluate the effectiveness of various proposed remediation strategies.
