'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.
