Stripes ordering in self-stratification experiments of binary and ternary granular mixtures
The self-stratification of binary and ternary granular mixtures has been experimentally investigated. Ternary mixtures lead to a particular ordering of the strata which was not accounted for in former explanations. Bouncing grains are found to have an important effect on stratum formation. A complementary mechanism for self-stratification of binary and ternary granular mixtures is proposed.
