Often used for drying and mixing, spouted beds are fluidized by high-
speed gas jets to drive particle mixing. At right, MFIX-Exa is used to
simulate a spouted bed experiment recently studied at
<a href="https://doi.org/10.1016/j.partic.2017.02.008">NETL</a>.
The bed consists of 2.2M HDPE particles which are fluidized by
single-celled jet. The jet velocity is ramped linearly from zero,
exceeding 100m/s at breakthrough. The simulation was carried out on
NETL's Joule2 HPC using 1600 CPUs. The animation was

A fun MFIX-Exa simulation that shows the evolution of 100k elastic
particles in a fully periodic domain. Most of the domain is initially
static, except for a collection of particles which are given a thermal
(Maxwellian) speed in specific regions. Shock waves of momentum and
concentration emanate from the thermal regions as the granular gas
evolves to a homogeneous state. Animation shows particles colored by
velocity magnitude rendered by
<a href="https://ovito.org">Ovito</a>
and played back in reverse.
