Axial Particle Diffusion in Rotating Cylinders
We study the interface dynamics of a binary particle mixture in a rotating cylinder numerically. By considering only the particle motion in axial direction, it is shown that the initial dynamics can be well described by a one-dimensional diffusion process. This allows us to calculate a macroscopic diffusion constant and we study its dependence on the inter-particle friction coefficient, the rot...
متن کاملRadial segregation patterns in rotating granular mixtures: waviness selection.
We model the radial segregation patterns that form in a thin rotating drum partially filled with beads of two sizes. We predict that the waviness (or amplitude-to-wavelength ratio, denoted w) of a pattern should be subjected to low-pass filtering with a cutoff waviness w(c) that depends strongly on the fill level of the drum. Then we perform experiments and find that w</=w(c) for all patterns, ...
متن کاملRadial Segregation in a Two-Dimensional Rotating Drum
We simulate the size segregation of a binary mixture of granular material in a half filled two-dimensional rotating drum using the discrete elements method with linear contact forces. The dynamics of the segregation process is studied in detail as function of the angular velocity of the drum. We propose an order parameter to characterize the final amount of segregation and the segregation speed...
متن کاملStress Intensity Factor of Radial Cracks for Rotating Disks and Cylinders using Average Stress Method
This article utilizes the average stress method to obtain the stress intensity factor of rotating solid and hollow disks/cylinders containing a radial crack. It is assumed that the cracks are located radially at center, internal or external radius of the geometry. Results are shown for both of the plane stress and plane strain assumptions and are validated against the known data introduce...
متن کاملCentrifugal force induced by relativistically rotating spheroids and cylinders
Starting from the gravitational potential of a Newtonian spheroidal shell we discuss electrically charged rotating prolate spheroidal shells in the Maxwell theory. In particular we consider two confocal charged shells which rotate oppositely in such a way that there is no magnetic field outside the outer shell. In the Einstein theory we solve the Ernst equations in the region where the long pro...
