Computations of Granular Flow in a Hopper

  • E. Bruce Pitman
Part of the The IMA Volumes in Mathematics and Its Applications book series (IMA, volume 26)


The flow of granular material in a hopper is a common industrial problem, but it is a problem without a good solution. Classical theories treat the material as an incompressible continuum in steady plastic yield; such theories cannot explain experimentally observed dynamics and dilantcy. Investigation of dynamic theories which include density variation is just beginning. We review the classical theory of granular flow in bins and present some of the recent developments on compressible flows. We borrow ideas from computational fluid dynamics in order to develop a method for the numerical simulation of compressible hopper flow.
