Book Description
Capillary phenomena occur in both natural and human-made systems, from equilibria in the presence of solids (grains, walls, metal wires) to multiphase flows in heterogeneous and fractured porous media. This book, composed of two volumes, develops fluid mechanics approaches for two immiscible fluids (water/air or water/oil) in the presence of solids (tubes, joints, grains, porous media). Their hydrodynamics are typically dominated by capillarity and viscous dissipation. This first volume presents the basic concepts and investigates two-phase equilibria, before analyzing two-phase hydrodynamics in discrete and/or statistical systems (tubular pores, planar joints). It then studies flows in heterogeneous and stratified porous media, such as soils and rocks, based on Darcy’s law. This analysis includes unsaturated flow (Richards equation) and two-phase flow (Muskat equations). Overall, the two volumes contain basic physical concepts, theoretical analyses, field investigations and statistical and numerical approaches to capillary-driven equilibria and flows in heterogeneous systems

Book Description
Theory and Application of Multiphase Lattice Boltzmann Methods presents a comprehensive review of all popular multiphase Lattice Boltzmann Methods developed thus far and is aimed at researchers and practitioners within relevant Earth Science disciplines as well as Petroleum, Chemical, Mechanical and Geological Engineering. Clearly structured throughout, this book will be an invaluable reference on the current state of all popular multiphase Lattice Boltzmann Methods (LBMs). The advantages and disadvantages of each model are presented in an accessible manner to enable the reader to choose the model most suitable for the problems they are interested in. The book is targeted at graduate students and researchers who plan to investigate multiphase flows using LBMs. Throughout the text most of the popular multiphase LBMs are analyzed both theoretically and through numerical simulation. The authors present many of the mathematical derivations of the models in greater detail than is currently found in the existing literature. The approach to understanding and classifying the various models is principally based on simulation compared against analytical and observational results and discovery of undesirable terms in the derived macroscopic equations and sometimes their correction. A repository of FORTRAN codes for multiphase LBM models is also provided.

Book Description
The book focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure. Upscaled models are developed and it is shown that the presence of material heterogeneities may give rise to additional non-equilibrium terms in the governing equations or to hysteresis in the averaged constitutive relationships.

Book Description
The Adomian decomposition method enables the accurate and efficient analytic solution of nonlinear ordinary or partial differential equations without the need to resort to linearization or perturbation approaches. It unifies the treatment of linear and nonlinear, ordinary or partial differential equations, or systems of such equations, into a single basic method, which is applicable to both initial and boundary-value problems. This volume deals with the application of this method to many problems of physics, including some frontier problems which have previously required much more computationally-intensive approaches. The opening chapters deal with various fundamental aspects of the decomposition method. Subsequent chapters deal with the application of the method to nonlinear oscillatory systems in physics, the Duffing equation, boundary-value problems with closed irregular contours or surfaces, and other frontier areas. The potential application of this method to a wide range of problems in diverse disciplines such as biology, hydrology, semiconductor physics, wave propagation, etc., is highlighted. For researchers and graduate students of physics, applied mathematics and engineering, whose work involves mathematical modelling and the quantitative solution of systems of equations.

Book Description
Graphical depictions of abstract concepts have played a major role in the formulation and communication of ideas since prehistoric times. The invention of photography in the nineteenth century and more recent advances in visualization techniques have catalyzed an enormous wealth of insights into every field of science and engineering by extending our senses far beyond our natural sensorial capabilities. The field of porous media has also benefited enormously from these developments in visualization techniques. Indeed, improvements in these techniques have led to the better morphological characterization of porous media and an enhanced understanding of the assorted physical processes, such as mass transport, capillarity, swelling, and fracturing, that can occur at the pore level. These observations, in turn, have led to superior usage practices for existing porous materials and the design of new products with porous media. Therefore, this bilingual English-Spanish album is aimed at providing a collection of state‐of‐the‐art visualizations of the diverse aspects of porous media that will serve as a reference in education and research. To cover all these aspects properly, the album is organized into seven thematic parts. Each part includes a collection of chapters with images accompanied by a brief English-Spanish description of the novelty of the observation, the visualization technique used, and the phenomenological insights gained. Las representaciones gráficas de conceptos abstractos han jugado un papel importante en la formulación y comunicación de ideas desde tiempos prehistóricos. La invención de la fotografía en el siglo XIX y los avances más recientes en las técnicas de visualización han catalizado una enorme riqueza de conocimientos en todos los campos de la ciencia y la ingeniería al extender nuestros sentidos mucho más allá de nuestras capacidades sensoriales naturales. El campo de los medios porosos también se ha beneficiado enormemente de estos avances en las técnicas de visualización. De hecho, las mejoras en estas técnicas han llevado a una mejor caracterización morfológica de los medios porosos y una mejor comprensión de los diversos procesos físicos, como el transporte de masa, la capilaridad, la hinchazón y la fractura, que pueden ocurrir a nivel de poro. Estas observaciones, a su vez, han llevado a mejores prácticas de uso para los materiales porosos existentes y al diseño de nuevos productos con medios porosos. Por lo tanto, este álbum bilingüe inglés y español tiene como objetivo proporcionar una colección de visualizaciones del estado del arte de los diversos aspectos de los medios porosos que servirán como referencia en la educación y la investigación. Para cubrir adecuadamente todos estos aspectos, el álbum está organizado en siete partes temáticas. Cada parte incluye una colección de capítulos con imágenes acompañadas de una breve descripción en inglés y español de la originalidad de la observación, la técnica de visualización utilizada y los conocimientos fenomenológicos obtenidos.

Book Description
In this standard reference of the field, theoretical and experimental approaches to flow, hydrodynamic dispersion, and miscible displacements in porous media and fractured rock are considered. Two different approaches are discussed and contrasted with each other. The first approach is based on the classical equations of flow and transport, called 'continuum models'. The second approach is based on modern methods of statistical physics of disordered media; that is, on 'discrete models', which have become increasingly popular over the past 15 years. The book is unique in its scope, since (1) there is currently no book that compares the two approaches, and covers all important aspects of porous media problems; and (2) includes discussion of fractured rocks, which so far has been treated as a separate subject. Portions of the book would be suitable for an advanced undergraduate course. The book will be ideal for graduate courses on the subject, and can be used by chemical, petroleum, civil, environmental engineers, and geologists, as well as physicists, applied physicist and allied scientists that deal with various porous media problems.

Book Description
This textbook integrates classic principles of flow through porous media with recently developed stochastic analyses to provide new insight on subsurface hydrology. Importantly, each of the authors has extensive experience in both academia and the world of applied groundwater hydrology. The book not only presents theories but also emphasizes their underlying assumptions, limitations, and the potential pitfalls that may occur as a result of blind application of the theories as 'cookie-cutter' solutions. The book has been developed for advanced-level courses on groundwater fluid flow, hydraulics, and hydrogeology, in either civil and environmental engineering or geoscience departments. It is also a valuable reference text for researchers and professionals in civil and environmental engineering, geology, soil science, environmental science, and petroleum and mining engineering.
