Abstract

ABSTRACT
A series of experiments done in which a granular material is exposed to horizontal
vibration within a rectangular container with two hallow cylinders mounted inside of it.
At high values of the peak acceleration relative to gravity novel swirl granular flows
are observed within the cylinders while the grains cascade down the outer surface of
the piles which fixed in the bottom of the container within the rectangular container
outside the cylinders. Computer simulations are performed which may support the
existent interpretation of the unusual aforementioned behaviour.
