Cold-flow demonstration of a circulating fluidized bed with gas and particle dynamics predicted by MFIX-Exa, rendering generated by Ascent in situ visualization. Six million 1mm diameter particles initially rest in a hopper (cylinder at left), flow down to fill the L-valve and are transported by a jet and sparger to the fluidized bed (cylinder at right), where they are violently fluidized before being transported up the riser, meeting a blind-T connection to the cyclone where the particles swirl around and are recycled to the hopper and the transport gas exits through the vortex finder at the top of the domain. This prototypical CFB is used by the MFIX-Exa team as a testbed for algorithm development aimed at performance improvement.

As LZ’s U.S. data center, NERSC provides support for data movement, processing, and storage – to the tune of 1PB of data annually. The data comes to NERSC from the Sanford Underground Research Facility in South Dakota via ESnet. Sofia Gomez, a graduate student at the University of Texas, El Paso, credits the Sustainable Research Pathways program at Berkeley Lab with sparking her interest in science and technology.

The simulation had ~30,000 neurons and ~30,000,000 compartments. The color indicates the flow of current through compartments. The visualization was created by Burlen Loring, Lawrence Berkeley National Laboratory.

The software helps scientists make more efficient use of their time and computing resources.
