Book Description
Notable for its thoroughness and clarity, this well-written graduate-level text presents the theoretical background of fluid flow from the standpoint of the transport phenomena, relating momentum transport to other transport mechanisms. The book is divided into three main sections: Part I-A Theoretical Background to Fluid Flow; Part II-Applications of the Basic Flow Equations; Part III-Extensions of the Basic Flow Equations. When this book was first written, there was no single text, suitable for graduate students, dealing with fluid motion. It remained for Professor Brodkey (Emeritus, Chemical Engineering, Ohio State University) to tie together the disparate threads of the topic in a clear, well-organized exposition. To make the book as accessible as possible to first-year graduate students, the author introduces the simplifying method of vector notation, and vector and tensor notation are developed as an integral part of the first few chapters. Part I provides a theoretical background to fluid flow, as well as introducing the equations of change and the various flux vectors of transport theory, and culminates in the derivation of the Navier-Stokes equations. Part II focuses on standard applications of the flow equations: inviscid flows, exact and boundary-layer solutions of the laminar-flow equations, integral methods, dimensional analysis and one-dimensional compressible flow. Part III, comprising the major portion of the book, covers phenomenological and statistical theories of turbulence, non-Newtonian phenomena and multiphase flow. Although it is designed for chemical engineering students, this book covers a wide range of topics not ordinarily found in fluid mechanics textbooks, making it an invaluable sourcebook for any engineer concerned with real-life fluid flow problems. The text includes carefully selected problems throughout to strengthen the reader's grasp of the material, and an exhaustive bibliography suggests further reading. Unabridged and corrected republication (2005) of the edition first published by Addison-Wesley Publishing Company, Reading, Mass., 1967. 268 illustrations (including 27 photographs). Preface. Author and subject indexes. Bibliography. Problems. xiv + 737pp. 6% x 9%. Paperbound.

Book Description
Processing of Solid-Liquid Suspensions is a collection of articles from several industrialists and academicians who are active in fundamental and applied research relating to handling and processing of particles in liquids. This collection of papers deals with the processes of interaction of particles with each other, with the surrounding liquid and process equipment, whereby knowledge of the mechanism of these interactions can be a sound basis for improving the design of the process equipment and create an optimum environment for the formation and processing of the particulate. The above notion is explained through analysis of the role of turbulent aggregation and breakup of particles in the formation of many solid products from aqueous solutions. This book also analyzes particle size and particulate crystals, whether as final products or as intermediates during processing. In the purification of proteins, two essential units of operation are used; precipitation and solid-liquid separation are analyzed, where theoretical considerations are reviewed. This text also discusses the application of model suspensions in the design of aerobic fermenters in practical industrial uses. High concentration of suspension preparations and solid suspension in liquid flourized beds or in stirred vessels are explained in more detail as to how these affect certain industries. This selection finally presents the progress made in developing design and methods needed by industry. Researchers, chemists, and scientists in industry, as well as advanced students with interests in formation and processing of stable suspensions and in advanced process engineering courses will find this textbook a valuable aid.
