Physicochemical Hydrodynamics Of Capillary Systems

This is the first book on physicochemical hydrodynamics that is devoted to capillary systems (surface layers, drops, films, jets, etc.) whose flow is greatly influenced by surface phenomena. Two- and three-dimensional hydrodynamics and rheology are formulated, as well as the kinetics and dynamics of surfactant adsorption in capillary systems. A new approach is elaborated for describing the most complicated capillary systems, like foams and polyhedral emulsions, as continuous media. The stability of disperse structures and the influence of gravity are also analysed. Although the book is purely theoretical, many consequences of practical importance are obtained. It will be of interest to university lecturers and postgraduates in colloid and surface science, as well as researchers and engineers dealing with capillary systems.

Since the first publication of the book, a surge of interest in physicochemical hydrodynamics (PCH) has produced a flurry of advances in the field, as researchers became aware of the subject’s practical applications across numerous disciplines. The Second Edition of Ronald F. Probstein’s Physicochemical Hydrodynamics is significantly expanded and revised to provide increased coverage of the field. All of the material was supplemented with problems for students, and a solutions manual is available for instructors. The continued demand for the book necessitates that the Second Edition be reprinted in paperback so that it may be more widely available to students and practitioners. This highly respected book emphasizes rational theory and its consequences to demonstrate the underlying unity of PCH, which allows diverse phenomena to be described in physically and mathematically similar ways. Physicochemical Hydrodynamics communicates the fundamentals while, at the same time, conveying the importance of applications of PCH to a variety of fields, including: mechanical, chemical, and environmental engineering; materials science, biotechnology, microfluidics, and fluid aspects of nanotechnology. Numerous illustrations, analogies, and examples highlight the text and help to clarify and solidify students’ and professionals’ understanding of the material.

This book contains lecture notes and invited contributions presented at the NATO Advanced Study Institute and EPS Liquid State Conference on PHYSICOCHEMICAL HYDRODYNAMICS-PCH: INTERFACIAL PHENOMENA that were held July 1-15, 1986, in LA RABIDA (Huelva) SPAIN. Although we are aware of the difficulty in organizing the contents due to the broad and multidisciplinary aspects of PCH-Interfacial Phenomena, we have tried to accomodate papers by topics and have not followed the order in the presentation at the meetings. There is also no distinction between the ASI notes and Conference papers. We have done our best to offer a coverage as complete as possible of the field. However, we had difficulties coming from the fact that some authors were so busy that either did not find time to submit their contribution or did not have time to write a comprehensive paper. We also had to cope with very late arrivals, postdeadline valuable contributions that we felt had to be included here. Our gratitude goes to the NATO Scientific Affairs Division for its economic support and to the EPS Liquid State Committee for its sponsorship. Financial support also came from Asociacion Industrias Quimicas-Huelva (Spain), Caycit-Ministerio De Educacion Y Ciencia (Spain), Canon-Espana (Spain), Citibank-Espana (Spain), CNLS-Los Alamos Nat. Lab. (U. S. A. ), CSIC (Spain), EPS, ERT (Spain), ESA, Fotonica (Spain), IBM-Espana (Spain), Junta De Andalucia (Spain), NATO, NSF (U. S. A. ), ONR-London (U. S. A.

Physicochemical Hydrodynamics: An Introduction aims to provide an introduction to physicochemical hydrodynamics (PCH), which deals with the interaction between fluid flow and physical, chemical, and biochemical processes. PCH has applications in many areas of science and technology and is a rapidly expanding field. Emphasis of this book is on rational theory and its consequences, with the purpose of showing the underlying unity of PCH, in which diverse phenomena can be described in physically and mathematically similar ways. The magic of this unity is shown in the similar manner in which solutes concentrate in a flow containing chemically reacting surfaces, reverse osmosis membranes, and electrodialysis membranes or the similarity of particle motions in sedimentation, centrifugation, ultrafiltration, and electrophoresis. Problems are included at the end of each chapter and are ordered following the sequence in which the material is set out. The questions range in difficulty, with most requiring an analytic development, but with some asking only for a descriptive answer. All problems are intended to illustrate the ideas presented, though often the solution goes beyond the explicit discussion in the book, with the answer constituting a generalization or extension of the text material. This book is an essential source of information for students majoring in the field of PCH.

Written by the founder of the field, this practice-oriented guide summarizes the author's breakthrough research results and their applications in chemical technology. The book adopts an entirely novel approach, describing the physical chemistry of structure formation and materials synthesis under dynamic conditions. It begins by developing the general theory in the first two chapters with as little mathematics as necessary and substantiated by experimental results in each case. The following chapters deal with the fundamental aspects of rheology, vibrorheology, and superfluidity of structured dispersed systems within the framework of physicochemical dynamics, while the final chapter exemplifies the technological applications of the developed methodology using real-life problems of materials science and chemical engineering. The authoritative guide to physicochemical dynamics.

The book aims at describing the most important experimental methods for characterizing liquid interfaces, such as drop profile analysis, bubble pressure and drop volume tensiometry, capillary pressure technique, and oscillating drops and bubbles.

This book provides a sound basis in the challenging area of the mechanics of unsaturated geomaterials. The objective is to supply the reader with an exhaustive overview starting from the basics and covering the most recent theories and applications (i.e. natural disasters, nuclear waste disposal, oil and agriculture productions). The presentation of the fundamental concepts is based on an interdisciplinary approach, in the areas of soil, rock and cement-based material mechanics.
