Gas-solid flows are involved in numerous industrial processes and occur in various natural phenomena. This authoritative book addresses the fundamental principles that govern gas-solid flows and the application of these principles to various gas-solid flow systems. The book is arranged in two parts: Part I deals with basic relationships and phenomena, including particle size and properties, collision mechanics, momentum transfer, heat and mass transfer, basic equations, and intrinsic phenomena in gas-solid flows. Part II discusses gas-solid flow systems of industrial interest such as gas-solid separators, hoppers and standpipes, dense-phase fluidised beds, fluidised beds, pneumatic conveying systems, and heat and mass transfer in fluidisation systems. As a comprehensive text on gas-solid flows, including end-of-chapter problems, this book is aimed at graduate students, but will also be useful to a broad range of engineers and applied scientists. • Only current text on the subject, written by an internationally respected authority • Written with a multidisciplinary focus for use by a broad range of engineers and applied scientists • Includes numerous worked examples and homework problems'This is a useful book for the novice researcher, as well as representing a worthwhile addition to the reference library of the more established researcher in the field. The treatment of the subject area is well served by thorough derivations of the working equations, and the illustrations provided by worked examples are an effective teaching tool. The generous provision of examples, problems and solutions in each chapter allows the book to be adopted readily as a textbook for postgraduate taught courses in engineering and applied science disciplines ... The overall print quality and the clarity of layout are also highly commendable.' Chemistry in Britain'The broad coverage provided by this book makes it an excellent source of information for those who need to understand the rudiments of gas/solid flow and how these principles are exploited by industry.' Chemical Engineering Progress'This is a well-written book on gas-solid flows written from the particle technology perspective. It provides a well-illustrated, integrated, and authoritative account of the basic principles that include the essential physics underlying gas-solid flows. It also contains excellent classical and state-of-the-art material on applications of gas-solid flow systems. It is recommended as a textbook for teaching graduate students and advanced graduate students who have good mathematical backgrounds, including vector analysis and partial differential equations. Because of its depth, breadth, and clarity, the book would also be valuable for practitioners and research scientists working in the gas-solid flow area as a primary reference source.' Jaikrishnan R.
