Abstract

The mechanics of flowing granular materials such as coal, sand, agricultural products, fertilizers, dry chemicals, metal ores, etc., and their flow characteristics have received considerable attention in recent years. In this paper, the governing equations for the flow of granular materials are derived using a continuum approach. For a fully developed flow of these materials down an inclined plane, the equations reduce to a system of coupled non-linear ordinary differential equations for the case where the material properties are assumed to vary quadratically with the volume fraction. The boundary value problem is solved numerically and the results are presented for the volume fraction and velocity profiles.
