Segregation-pattern reorientation of a granular mixture on a horizontally oscillating tray.
Reorientation of the segregation pattern of a binary granular mixture on a two-dimensional horizontally oscillating tray is numerically realized. The mixture consists of large and heavy particles and small and light particles, and the segregation pattern shows a transition between a striped pattern perpendicular to the oscillation and one parallel to the oscillating direction according to the change of area fractions of the two types of particle. The transition mechanism is discussed on the basis of a simplified one-dimensional dynamics.
