This book bridges the gap between the theoretical work of the rheologist and the practical needs of those who have to design and operate the systems in which these materials are handled or processed. This new edition addresses the rapid advances that are occurring in all aspects of the topics covered in this book, such as new measurement techniques or new constitutive equations and more reliable information based on numerical simulations. New solved examples are added in each chapter, along with a list of problems at the end of the book.
