This volume contains the invited lectures presented during the NATO/ASI conducted in Pullman, Washington, July 9-18, 1989. This is the third in a series of NATO/ASIs on transport phenomena in porous media. The first two, which took place at Newark, Delaware in 1982 and 1985, are devoted to various topics related to the Fundamentals of Transport Processes in Porous Media. The contents of the books resulting from previous NATO/ASIs are given at the end of this book. Transport of extensive quantities such as mass of a fluid phase, mass of chemical species carried by a fluid phase, energy and electric charge in porous media, as encountered in a large variety of engineering disciplines, is an emerging interdisciplinary field. The groundwater flow, the simultaneous flow of gas, oil and water in petroleum reservoirs, the movement and accumulation of pollutants in the saturated and unsaturated subsurface zones, thermal energy storage in reservoirs, land subsidence in response to charges in overburden loads, or to pumping of fluids from underground formations, wave propagation in seismic investigations or as produced by earthquakes, chemical reactors, water flow through sand filters and the movement of fluids through kidneys, may serve as examples of fields in which the theory of transport in porous media is employed.

This volume contains the lectures presented at the NATO Advanced Study Institute that took place at the University of Delaware, Newark, Delaware, July 18-27, 1982. The purpose of this Institute was to provide an international forum for exchange of ideas and dissemination of knowledge on some selected topics in Mechanics of Fluids in Porous Media. Processes of transport of such extensive quantities as mass of a phase, mass of a component of a phase, momentum and/or heat occur in diversified fields, such as petroleum reservoir engineer ing, groundwater hydraulics, soil mechanics, industrial filtration, water purification, wastewater treatment, soil drainage and irri gation, and geothermal energy production. In all these areas, scientists, engineers and planners make use of mathematical models that describe the relevant transport processes that occur within porous medium domains, and enable the forecasting of the future state of the latter in response to planned activities. The mathe matical models, in turn, are based on the understanding of phenomena, often within the void space, and on theories that re late these phenomena to measurable quantities. Because of the pressing needs in areas of practical interest, such as the develop ment of groundwater resources, the control and abatement of groundwater contamination, underground energy storage and geo thermal energy production, a vast amount of research efforts in all these fields has contributed, especially in the last t~o decades, to our understanding and ability to describe transport phenomena.

Porous Media: Fluid Transport and Pore Structure presents relevant data on the role of pore structure in terms of transport phenomena in pore spaces. The information is then applied to the interpretation of various experiments and results of model calculations. This book emphasizes the discussion of ""flow through porous media"" in terms of interactions among the three main factors. These factors are transport phenomena, interfacial effects, and pore structure. An introductory chapter opens the text and presents some of the basic concepts and terms that will be encountered all throughout. Chapters 2 to 4 focus on the important foundations of the physical phenomena as applied in the pore space of porous media. These foundations are capillarity, pore structure, and single phase flow and diffusion. Chapters 5 to 7 discuss more in detail the different applications of pore structure to various operations and processes. Some of the concepts covered in this part of the book include flow and/or diffusion through a porous medium, simultaneous flow of immiscible fluids and immiscible displacement, and miscible displacement and hydrodynamic dispersion. This book is a good reference to students, scientists, and engineers in the field of chemistry, physics, and biology.

Sophisticated models of the movement of particles, particularly bacteria and viruses, through porous media have been developed, but have met with limited success when compared to field observations some argue that the poor predictive capabilities of the models are due in part to the fact that most of the sophisticated models are tied to an assumptions of homogeneity within the flow field. In previous work, the structure of random percolation fields has been investigated and suggests application of percolation theory to heterogeneous porous media. One conclusion from this study as applied to particle transport is that as the distribution of pore throat sizes takes on variation in the third dimension, the probability of finding a continuous flow path with large throat size increases. One interpretation of this work, within the current context, leads to an argument that a saturated medium will become more open to transport of particles as the medium takes on three dimensional structure. The central hypothesis of the current project is therefore be stated: Particles which are suspended within the pore fluids of media demonstrating three-dimensional heterogeneities will be transported at higher average velocities and with less trapping than particles which are suspended in the pore fluids of media demonstrating one- or two-dimensional heterogeneities. This dependence on dimension is a function of the dimensional character of the heterogeneity, the length scales of the heterogeneity, the size of the particles, the hydrodynamics of the flow field, the degree of saturation of the medium, and the medium/particle interaction.

(Cont.) The entrapment mechanism was physical interlocking on surface roughness and physical straining at the contact points. Particle sedimentation and particle re-entrainment as a result of flow field perturbations were the main mechanisms contributing to the hindrance of particles. Changes in the concentrations of particles that were entrapped or hindered were observed with distance from the particle injection point. These changes, which became more significant as the fluid velocity decreased, were attributed to particle size distribution effects. Experiments conducted with an upward pore fluid velocity supported the hypothesis that particle entrapment and hindrance are driven by gravity. The comparison of the experimental results with particle transport models based on macroscopic mass balance equations demonstrated some of the short-comings of these models. Drainage tests performed using the geotechnical centrifuge and the new visualization technique e also provided initial insight into discrete particle behavior in an unsaturated porous medium. The results of these tests show that particles were scavenged by the air-water interface, adsorbed on the air-water interface of the pendular rings, and were retained by film straining. Thus, it is believed that the visualization technique developed during this work can be used to further investigations of discrete particle transport behavior in partially saturated porous media.

Launches a series that intends to deal with topics as varied as atmospheric dynamics, coastal oceanography, subsurface flow and transport, lava flow, oil spills on the sea surface, indoor contamination and clean-room technology, risk assessment, data acquisition, and stochastic models. Introduces the general principles of diffusion in the subsurface environment and discusses the implications for the fate and transport of contaminants in the soils and groundwater. Emphasizes sorption and desorption and the dissolution kinetics of organic contaminants, both of which are limited by the slow speed of molecular diffusion. Also compiles methods for calculating the diffusion coefficients of organic compounds in aqueous solution or vapor phase through natural porous media.
