Quantitative modelling of granular suspension flows

A broad review is presented of the flow of particulate suspensions. The fundamental concepts are discussed and the governing equations described. Simplified horizontally uniform, box–model solutions are obtained and numerical integrations of the nonlinear shallow–water equations are presented, along with a brief description of an approach using the full power of the techniques of computational fluid dynamics. Extra situations, such as the influence of a mean external flow, interstitial fluid which is less dense than the ambient, plumes, entrainment of the ambient, and polydispersivity are reviewed. Applications from engineering and the Earth sciences are described.
