Muna Tageldin, a Ph.D. student from Marquette University, presents her research at the culminating poster session for the 2022 CSA Summer Program. 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.
