We formulate a phenomenological model for the segregation of binary mixtures of rough and smooth granular materials in a rotating drum. Our model successfully replicates a range of experimental behaviours, e.g., rapid radial segregation; slow axial segregation; and nonuniform radial structure of axial bands. We present some analytical results and detailed numerical results for our model.

We investigate the error induced by only considering binary collisions in the momentum transport of hard-sphere granular materials, as is done in kinetic theories. In this process, we first present a general microscopic derivation of the momentum transport equation and compare it to the kinetic theory derivation, which relies on the binary collision assumption. These two derivations yield diffe...

Are There Long-Time Tails in Granular Flows?

The long-time tails in the current autocorrelation functions are one of the important characteristics in nonequilibrium physics.1), 2), 3), 4) It is known that the long tails are originated from the correlated collisions which cause anomalous transport behaviors such as the system size dependence of the transport coefficients.5), 6) The analysis of such behaviors is still an active subject in n...

We give an overview of the existence and regularity results for curvature flows and how these flows can be used to solve some problems in geometry and physics.
