This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "A capillary pressure curves provides important information about the porous system such as porosity, breakthrough pressure, fluid-solid wettability and capillary hysteresis. The measurement of capillary pressure curves is one of the most commonly adopted methods of measuring wettability in a porous system. However, to date these measurements are done only at room temperature because of the limitations of utilising existing equipment at higher temperatures. The capillary behaviour of liquid in porous system can be a different when subjected to harsh condition such as high temperature and pressure. An experimental setup has been designed and developed to measure air-water capillary pressure curves for gas diffusion layers (GDLs) used in polymer electrolyte membrane fuel cells at elevated temperatures. Experiments were conducted at various temperatures in the direction of increasing and decreasing temperatures for Toray 120 and Toray090 with varying PTFE loadings. Notable shifts in the capillary behavior were seen and in some cases the shifts were of the same size as PTFE addition. In untreated samples the results suggest that GDL wettability changes with temperature once the temperature dependence of the surface tension has been accounted for. In treated samples, however, the wettability remains more or less constant with temperature. This behavior is in agreement with the temperature dependent values of water contact angle on PTFE and graphite. Observed shift with temperature for treated samples are more or less reversible during decreasing temperatur" --
Book Synopsis Membrane Characterization by : José Ignacio Calvo Díez
Download or read book Membrane Characterization written by José Ignacio Calvo Díez and published by Walter de Gruyter GmbH & Co KG. This book was released on 2024-10-21 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane technology has become an essential tool in many industrial processes in which the separation or fractionation of various species is necessary to obtain or recover high value-added products. In these processes, the synthetic membranes usually play a filter role, being characterized by the size of the pores present in it, which delimit the size of the molecules to be separated. It is therefore necessary to have a precise knowledge of the characteristic size of said pores. In this book, the main techniques that can be used to determine the mean pore size and the pore size distribution of a synthetic membrane are analyzed and discussed, from the point of view of their theoretical basis, with special attention to equipment that should be used for each technique, as well as reviewing their advantages and disadvantages. Through this text, the researcher or responsible of the quality-control at membrane manufacturing companies will be able to know decide properly which of the porosimetric techniques is more adequate for the knowledge that needs to be obtained from their filters.

This book was released on 2012-12-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last two decades, the experimental technology for the study of high temperature solid-vapor and liquid-vapor equilibria has mushroomed so fast that· both academic and industrial research ers desirous of working in this field -- be they physical chemists, metallurgists, ceramists, petrologists, crystal chemists, or mem bers of any of the several branches of materials science -- find themselves in the situation that in order to learn the art of the latest techniques, a period of apprenticeship or residency needs be spent at an institution or laboratory currently engaged in this type of solid-vapor or liquid-vapor research. The tech niques for control of the vapor phase at total pressures of one atmosphere or greater have not been well defined in the literature. Therefore, the purpose of this volume will be to serve as a labora tory manual for the control, calibration, and measurement of high temperature-high pressure equilibria. The avowed aims of this treatment of experimental techniques are: (1) to give, in terms understandable at the graduate student level, the laboratory procedures necessary to the design and utilization of good experimental technique, (2) to list the limitations, dangers, and technical pitfalls inherent or intrinsic to the described techniques, (3) to give theory and specific data only where they are essential to the experimental design, (4) to give with each chapter references that are extensive enough to serve as a bibliography of the state-of-the-art of technique development within the last decade.

Book Synopsis Modeling Groundwater Flow and Contaminant Transport by : Jacob Bear
Download or read book Modeling Groundwater Flow and Contaminant Transport written by Jacob Bear and published by Springer Science & Business Media. This book was released on 2010-01-18 with total page 851 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use, and contamination. To face the challenge, good planning and management practices are needed. A key to the management of groundwater is the ability to model the movement of fluids and contaminants in the subsurface. The purpose of this book is to construct conceptual and mathematical models that can provide the information required for making decisions associated with the management of groundwater resources, and the remediation of contaminated aquifers. The basic approach of this book is to accurately describe the underlying physics of groundwater flow and solute transport in heterogeneous porous media, starting at the microscopic level, and to rigorously derive their mathematical representation at the macroscopic levels. The well-posed, macroscopic mathematical models are formulated for saturated, single phase flow, as well as for unsaturated and multiphase flow, and for the transport of single and multiple chemical species. Numerical models are presented and computer codes are reviewed, as tools for solving the models. The problem of seawater intrusion into coastal aquifers is examined and modeled. The issues of uncertainty in model input data and output are addressed. The book concludes with a chapter on the management of groundwater resources. Although one of the main objectives of this book is to construct mathematical models, the amount of mathematics required is kept minimal.
Book Synopsis Capillary Pressure Measurement in Glass Bead Porous Media and Gas Diffusion Layers by : Deepthi Sharan Thatiparti
Download or read book Capillary Pressure Measurement in Glass Bead Porous Media and Gas Diffusion Layers written by Deepthi Sharan Thatiparti and published by . This book was released on 2010 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fluid flow through porous media requires understanding the behavior of the capillary properties and pore-size characteristics of the porous medium. The similarity experiment is conducted to study the capillary pressure and saturation relationship using the continuous liquid intrusion and liquid drainage in the Glass bead porous medium and the capillary behavior is compared to the Gas diffusion layer porous medium used in Polymer electrolyte membrane fuel cell. While the liquid-air capillary pressure curves in the glass bead porous medium are found to depend on the glass bead diameter, surface wettability and pore-size characteristics, they depend on the GDL sample thickness and Teflon content in the GDL. The main objective is to understand the capillary behavior in the porous medium by controlling the surface wettability, pore-size characteristics and glass bead diameter of the porous medium. A capillary pressure - liquid saturation relation is derived based on the experimental data at room temperature and the relative permeability - saturation correlation for the gas diffusion layers under the given conditions was obtained using the Wyllie model. Finally the empirical fit of the capillary pressure-saturation correlations is validated for the GDL porous media and the optimum conditions for the fuel cell operation is evaluated for the efficient fuel cell operation.
