Available in PDF, EPUB and Kindle. Book excerpt: FEFLOW is an acronym of Finite Element subsurface FLOW simulation system and solves the governing flow, mass and heat transport equations in porous and fractured media by a multidimensional finite element method for complex geometric and parametric situations including variable fluid density, variable saturation, free surface(s), multispecies reaction kinetics, non-isothermal flow and multidiffusive effects. FEFLOW comprises theoretical work, modeling experiences and simulation practice from a period of about 40 years. In this light, the main objective of the present book is to share this achieved level of modeling with all required details of the physical and numerical background with the reader. The book is intended to put advanced theoretical and numerical methods into the hands of modeling practitioners and scientists. It starts with a more general theory for all relevant flow and transport phenomena on the basis of the continuum approach, systematically develops the basic framework for important classes of problems (e.g., multiphase/multispecies non-isothermal flow and transport phenomena, discrete features, aquifer-averaged equations, geothermal processes), introduces finite-element techniques for solving the basic balance equations, in detail discusses advanced numerical algorithms for the resulting nonlinear and linear problems and completes with a number of benchmarks, applications and exercises to illustrate the different types of problems and ways to tackle them successfully (e.g., flow and seepage problems, unsaturated-saturated flow, advective-diffusion transport, saltwater intrusion, geothermal and thermohaline flow).

Download or read book Two D Heat Transfer Through Porous Media with Heat Generation written by Benjamin Martinez (Jr.) and published by . This book was released on 1984 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigation develops an axisymmetric heat transfer-combustion model of a porous medium within a circular cylinder. System flow is governed by Darcy's law. Carbon and air properties are treated as variables of temperature. A combined continuity-Darcy equation, an oxygen mass balance equation, and energy balance equations (one each) for air and carbon, describe the conservation laws of the system. Transport mechanisms for oxygen mass transfer are molecular diffusion and convective transport, and an oxygen consumption term to account for combustion is included. Heat transfer mechanisms included in the model are conduction and convection. Radiation is accounted for at applicable boundaries only. Nonvolatile combustion is accounted for in the carbon energy and oxygen mass balance equations as a heat generation term of Arrhenius type. The numerical solution of four coupled, nonlinear, transient partial differential field equations is accomplished using the Galerkin formulation of the Finite Element Method. The effect of porosity of system behavior is examined. Additional keywords: Semenov model, and Numerical analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Heat and mass transfer in porous media under phase transition conditions has a great scientific and practical interest in solving of engineering and technical problems. Many industrial processes require the study of mathematical models for the development of both the technologies based on the phase transitions in porous media and experimental devices for the study of these processes. The main goal of the book is sequential and systematical consideration from unified view point the heat and mass transfer processes occurring in heterogeneous porous media (soil-water-ice) under phase transition conditions. New solutions and also analytical and numerical models are provided for the analysis of the freezing (thawing) processes in the soils, which are arisen in various regions such as Canada, The United States and North-East Asia. For multiphase media, the system of differential equations with allowance of phase transition kinetics is derived. In contrast to the most studies, considering a two-zone model for the solution (classical approach), we suppose the existence of a region of intensive phase transitions freezing or kinetic zone, which is characterised by non-instantaneous kinetics of crystallisation. As a new and important result, the criterion for freezing zone formation as a function of soil properties and freezing conditions is derived. The book also includes the new experimental method and results relating to determination of the important characteristic for the kinetic model time of the water crystallisation in freezing porous media. A new approach for the modelling the secondary frost heave is proposed and described in detail. The new results, concerning with frost heave distribution and its rate, are presented. On the basis of perturbation method in a two-dimensional coupled heat and mass transfer model, for the first time, the analytical criteria in dimensionless form for the both dynamic and morphological instability are derived. Employing Fourier synthesis, an actual front shape evolution is calculated. In this way the new physical results are obtained. All results of modelling represented in book have an appropriate mathematical justification, are illustrated by comparison with appropriate experimental data and, where it is possible, with calculation results of other authors. The models and results presented in this book can be used for the prediction of the main engineering characteristics for the practical problems.

Available in PDF, EPUB and Kindle. Book excerpt: The simulation of complex engineering problems often involves an interaction or coupling of individual phenomena, which are traditionally related by themselves to separate fields of applied mechanics. Typical examples of these so-called multifield problems are the thermo-mechanical analysis of solids with coupling between mechanical stress analysis and thermal heat transfer processes, the simulation of coupled deformation and fluid transport mechanisms in porous media, the prediction of mass transprot and phase transition phenomena of mixtures, the analysis of sedimentation processes based on an interaction of particle dynamics and viscous flow, the simulation of multibody systems and fluid-structure interactions based on solid-to-solid and solid-to-fluid contact mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: Nonprofit organizations are suffering from the continuing economic downturn. Donations are decreasing while demand for services is growing, forcing these organizations to be increasingly efficient and effective with their funds. This book introduces the reader to the basic concepts of project management. It provides approaches and templates to help nonprofit managers quickly implement practices to help them manage their limited resources, both financial and volunteer. The book also provides a tool to help the project team determine which practices are most appropriate. The book explores how social media and other technology tools can be used to assist in the management of time-sensitive projects and shows how project portfolio management can be a tool to assist in communications with boards of directors and other governing entities. The project portfolio is a tool that development office managers can easily implement and adopt to facilitate resource assignment. Finally, the book offers three case studies of nonprofit projects that went awry and shows how project management would have assisted.

Available in PDF, EPUB and Kindle. Book excerpt: Responding to concerns about global warming, carbon dioxide emissions, and the political instability that threatens the US supply, this book enables management, system analysts, and performance engineers to develop and apply an operating strategy for the on-line optimization and control of energy systems in industrial plants. It provides proven techniques for analysis that can guide equipment selection and flowsheet adjustments to reduce plant energy consumption without affecting the productive capacity of the plant. Originating in the 1970s and 1980s when high energy costs and the OPEC crises fostered energy conservation, these techniques have been applied successfully in many industries in the United States, as well as in several industrialized countries in the Middle and Far East.
