Especially, if the grain shapes differ significantly from a sphere the possibility of flow alignment exists and it takes not much imagination to visualize that a sliding motion of the particles is affected by their mutual alignment. The approach we are taking here is based on a continu

This segregation according to particle size has been our motivation to develo

We demonstrate the existence of a solution in which the medium segregates by particle size. For a mixture of small and large particles (. = 2),we use methods of Smoller [30]

Group Theoretic Methods and Similarity Solutions of the Savage—Hutter Equationsurface flow of granular avalanches. All similarity solutions of this system are found by means of group analysis. The family of solutions which are invariant to stretching transformations is investigated in greater detail. Explicit solutions are constructed in three cases and their physical interpretation is given.

Fazit,imilarity and shock wave solutions are reviewed and a simple mass-coupling to a rigid body of grains is used to investigate the steady mixing of grains of equal size in a rotating tumbler of circular cross-section.
