On granular flows: From kinetic theory to inertial rheology and nonlocal constitutive models
Diego Berzi
Abstract
The case is made that the kinetic theory of granular gases provides the long-sought universal framework to predict the flow of realistic particles from dilute to very dense conditions. In so doing, the popular inertial rheology and its nonlocal extension to deal with heterogeneities based on the granular fluidity concept are derived as special limits of the kinetic theory.
