Abstract: The phrase ’granular material’ is used to describe a large number of discrete
solid, macroscopic particles that lose energy whenever the particles collide.  One might
naively imagine that such systems would exhibit similar behaviour to traditional fluid
and solid mechanics.  However, we present two problems that superficially appear to be
extremely simple but yield surprisingly rich dynamics that have no analogue in
traditional mechanics.  Firstly, we consider a dilute stream of particles that collides
with an oblique planar wall.  Secondly, we show several surprising phenomena that occur
in an extremely simple system of a single frictionless, inelastic, spherical particle
falling under gravity through a symmetric funnel.  

Bio: Jonathan Wylie obtained his PhD and was subsequently awarded a Junior Research
Fellowship from King’s College, Cambridge.  He then held research fellow positions in
Woods Hole Oceanographic Institution and the University of Toronto before joining the
City University of Hong Kong.  His research interests include fluid mechanics, granular
materials, ion transport and the mathematical modelling of geophysical systems.
