Spouted Bed

+

Eruption! The moment of spout breakthrough

+
+
+
+ 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 + NETL. + 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 + The animation was rendered with + Blender. +

Soft-sphere molecular dynamics simulation with heavily designed initial conditions

+

+
+
+ 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 + Ovito + and played back in reverse. +
