Dilatant double shearing theory applied to granular chute flow (Q678912)

The basic flow properties such as density and velocity profiles are not yet exhaustively examined for the steady flow of a granular material down a plane inclined slope. Thus, the authors examine a dilatant double shearing theory for chute flow, assuming that the perpendicular component of velocity does not vanish. An explicit analytical form for the perpendicular velocity profile is deduced and, assuming a linearly decreasing density profile, numerical results for nonlinear profiles are plotted into diagrams.
