Title: Viscoplastic flow over an inclined surface

Subjects: Fluid mechanics, Properties of matter, Viscoplasticity, Material plasticity
Abstract: Abstract: We review viscoplastic flow over inclined surfaces, focusing on constant-flux extrusions from small vents and the slumping of a fixed volume of material. Lubrication theory is used for shallow and slow flows to reduce the governing equations to a nonlinear diffusion-type equation for the local fluid depth; this model is used as the basis for exploration of the problem. Theory is compared to experiments. A number of complications and additional physical effects are discussed that enrich real situations. [Copyright &y& Elsevier]
