The goal of this is book to give a detailed presentation of multicomponent flow models and to investigate the mathematical structure and properties of the resulting system of partial differential equations. These developments are also illustrated by simulating numerically a typical laminar flame. Our aim in the chapters is to treat the general situation of multicomponent flows, taking into account complex chemistry and detailed transport phe nomena. In this book, we have adopted an interdisciplinary approach that en compasses a physical, mathematical, and numerical point of view. In par ticular, the links between molecular models, macroscopic models, mathe matical structure, and mathematical properties are emphasized. We also often mention flame models since combustion is an excellent prototype of multicomponent flow. This book still does not pretend to be a complete survey of existing models and related mathematical results. In particular, many subjects like multi phase-flows , turbulence modeling, specific applications, porous me dia, biological models, or magneto-hydrodynamics are not covered. We rather emphasize the fundamental modeling of multicomponent gaseous flows and the qualitative properties of the resulting systems of partial dif ferential equations. Part of this book was taught at the post-graduate level at the Uni versity of Paris, the University of Versailles, and at Ecole Poly technique in 1998-1999 to students of applied mathematics.

The book introduces the topic of geochemical modeling of fluids in subsurface and hydrothermal systems. The intention is to serve as a textbook for graduate students in aqueous, environmental and groundwater geochemistry, despite the fact that its focus is on the special topic of geochemistry in hydrothermal systems, it also provides new insights for experienced researchers with respect to the topic of reactive transport. The overall purpose is to give the reader an understanding of the processes that control the chemical composition of waters in hydrothermal systems and to highlight the interfaces between chemistry, geothermics and hydrogeology. From the reviews: "..is a nice, compact introduction to the principles of modeling coupled fluid flow and fluid-mineral reactions in active geothermal systems, as used for heating and electricity generation."

Reservoir simulation is an important tool for petroleum engineers to predict oil production andoptimize the management of oil fields. Fluids in oil and gas reservoirs are complex. In many cases,reservoir fluids consist of three or more phases and contain a large number of species that can reactwith each other. Many existing models (black oil, compositional and reactive transport models)were developed to simulate fluids with a specific fluid characterization. In this dissertation, ageneral modeling framework is developed that allows for simulation of different fluid types andprocesses. Based on the general framework we developed a new in-house simulator that we namedPennSim.Reservoir simulators spend over 90% CPU time on the linear solver for reservoir models withover one million grid blocks. The performance of iterative linear solvers depends on the choice ofthe preconditioner, the design of which depends on the knowledge of the PDEs. We designedadvanced multistage preconditioners based on the PDE structure. New decoupling strategies wereproposed for the constraint pressure residual method. Advantageous performance is demonstratedand over three times speed-up is shown.We applied the general modeling framework to design novel models to explore the mechanismsof enhanced oil recovery (EOR). With coupled surface complexation reaction and multiphase flow,we proposed a numerical model for low salinity waterflooding for carbonates. The wettablilityalteration was modeled by detailed description of fluid and surface reactions. Our model is the firstpredictive model for low salinity EOR in carbonates. We also designed the coupled compositionaland reactive model for water-alternating CO2 injection. Injectivity changes were predicted forinjection water with different compositions.This dissertation aims to cover the generic modeling, numerical simulation and fast iterativesolvers for multiphase multicomponent flow and transport in porous media. PennSim wasdeveloped and its manual is available in supplemental materials.
