An Introduction to Granular Flow By K. Kesava Rao Prabhu R. Nott, Cambridge University Press, Cambridge (UK), 2008 ISBN-13 978-0-521-57166-1 This book goes far beyond the promise of its title, and it is a wide compendium of the present state of the knowledge in the modeling of stress and velocity distributions for flowing and non flowing granular materials. This makes this book an important reference for scientists and engineers working on granular matter. The book is not only theory and most of the chapters start with an overview of the experimental observations that justify the specific modeling approach proposed in the corresponding chapter. In the first chapter the fundamentals of the physics and the basic balance equation that are relevant to particulate systems are presented. Chapter 2 to 4 are devoted mainly to plain silo flow and, more in general, to those systems that can be approached by continuum mechanics in two dimensions. The simplified geometry allows to introduce and discuss in simpler cases most of the assumptions made in the stress and strain analyses involving granular materials. Chapters 5 and 6 extend the application of continuum mechanics to cases involving tree dimensional flow and, in particular, to axy-symmetric bins. The most important powder constitutive equations involving yield and non yield conditions are also discussed in these chapters. The last four chapters are devoted to the modeling of fast granular flow by the approach of the kinetic theory. In particular, chapters 7 and 8 address the kinetic theory that can be derived by assuming smooth inelastic particles and its applications. In chapter 9 the velocity distribution functions and the particulate solids constitutive equation are compared for the two cases of smooth and rough particles. Two features of this book make it suitable for adoption as a text book in a university course for graduate students on granular flow. The first is represented by more than sixty pages of 11 appendixes most of which summarize the basics of the tensor analysis. The second feature is represented by the large number of exercises promoting meditation on the main concepts presented in the text and their application.
