Download or read book Numerical Simulations of Heterogeneous Chemical Reactions Coupled to Fluid Flow in Varying Thermal Fields written by and published by . This book was released on 1991 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical simulator of reactive chemical transport with coupling from precipitation-dissolution reactions to fluid flow, via changes of porosity and permeability, is applied to precipitation-dissolution of quartz and calcite in spatially and temporally variable fields of temperature. Significant effects on fluid flow are found in the quartz-silicic acid system in the presence of persistent, strong gradient of temperature. Transient heat flow in the quartz-silicic acid system and in a calcite-calcium ion-carbonato species system produces vanishingly small effects on fluid flow.

Book Synopsis Numerical Simulation of Hydrothermal Convection Within Discretely Fractured Porous Media with Application to the Seafloor by : Jianwen Yang

This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid circulation driven by thermal gradients is an important physical phenomenon characteristic of the subsurface of the earth. My thesis contributes to investigating the physical behaviour and computational techniques of heat transport and fluid flow in explicitly fractured porous media. Both analytical and numerical methods are developed to study problems related in particular to hydrothermal convective systems in the mid-ocean ridge environment. An analytical solution of the heat transport process in a single fracture is first derived for the impermeable host rock. For general hydrothermal convective systems, a numerical algorithm is developed. The algorithm is validated by comparing numerical results with analytical solutions. It is indicated discrete fractures not only initiate and maintain hydrothermal convection but also greatly change an established convection pattern. The effect of anisotropic permeability fields on hydrothermal convection is studied both analytically and numerically. A more useful form of the Rayleigh number is defined, which contains the geometric mean of the vertical and horizontal permeabilities. The critical value for the onset of stable convection is derived analytically. It is shown that anisotropy resists the initiation of hydrothermal convection. An alternative theory is developed to explain the origin of small-scale seafloor heat-flow variations over a mid-ocean ridge flank where basement relief is not clear. It is indicated that inclusion of explicit fractures in upper oceanic crust promotes and maintains hydrothermal convection within the upper basalts. Consequently, the small-scale heat-flow variations are produced on the seafloor. A 3-D hydrothermal system within the TAG-like sulfide mound is examined. A range of models with different physical parameters and boundary conditions is investigated. Numerical results reveal that a central high-temperature zone is coincident with a non-magnetic zone inferred from magnetic data. Upflow fluid motion is along the vertical high-permeability column surrounding a central pipe. The maximum fluid velocity in the latter is in the order of the observed values.

Download or read book Hydrothermal Reactions and Techniques written by Zhan Shi and published by World Scientific. This book was released on 2003 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrothermal techniques have been widely used in the synthesis of advanced materials, the treatment of wastes, and the preparation and extraction of special chemicals. They have also been studied for the mimicking of geothermal processes. Nowadays, hydrothermal techniques and sciences play a very important role both in industry and in academia. This book includes contributions from chemists and chemical engineering scientists worldwide who are active in the field of hydrothermal reactions and techniques. The topics covered range from fundamentals of hydrothermal reactions, modeling of hydrothermal processes, new techniques for hydrothermal treatment, and new materials from hydrothermal systems to supercritical fluid reaction systems.

Download or read book Aqueous Systems at Elevated Temperatures and Pressures written by Roberto Fernandez-Prini and published by Elsevier. This book was released on 2004-07-06 with total page 767 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Association for the Properties of Water and Steam (IAPWS) has produced this book in order to provide an accessible, up-to-date overview of important aspects of the physical chemistry of aqueous systems at high temperatures and pressures. These systems are central to many areas of scientific study and industrial application, including electric power generation, industrial steam systems, hydrothermal processing of materials, geochemistry, and environmental applications. The authors’ goal is to present the material at a level that serves both the graduate student seeking to learn the state of the art, and also the industrial engineer or chemist seeking to develop additional expertise or to find the data needed to solve a specific problem. The wide range of people for whom this topic is important provides a challenge. Advanced work in this area is distributed among physical chemists, chemical engineers, geochemists, and other specialists, who may not be aware of parallel work by those outside their own specialty. The particular aspects of high-temperature aqueous physical chemistry of interest to one industry may be irrelevant to another; yet another industry might need the same basic information but in a very different form. To serve all these constituencies, the book includes several chapters that cover the foundational thermophysical properties (such as gas solubility, phase behavior, thermodynamic properties of solutes, and transport properties) that are of interest across numerous applications. The presentation of these topics is intended to be accessible to readers from a variety of backgrounds. Other chapters address fundamental areas of more specialized interest, such as critical phenomena and molecular-level solution structure. Several chapters are more application-oriented, addressing areas such as power-cycle chemistry and hydrothermal synthesis. As befits the variety of interests addressed, some chapters provide more theoretical guidance while others, such as those on acid/base equilibria and the solubilities of metal oxides and hydroxides, emphasize experimental techniques and data analysis. - Covers both the theory and applications of all Hydrothermal solutions - Provides an accessible, up-to-date overview of important aspects of the physical chemistry of aqueous systems at high temperatures and pressures - The presentation of the book is understandable to readers from a variety of backgrounds
