Experiment and simulation of high-speed gas jet penetration into a semicircular fluidized bed
William D. Fullmer, Jonathan E. Higham, Roberto Porcu +4
This work marks the third in a series of experiments that were in a semi-circular, gas-fluidized bed with side jets. In this work, the particles are 1 mm ceramic beads. The bed is…
Performance comparison of CFD-DEM solver MFiX-Exa, on GPUs and CPUs
Shandong Lao, Aaron Holt, Deepthi Vaidhynathan +3
We present computational performance comparisons of gas-solid simulations performed on current CPU and GPU architectures using MFiX Exa, a CFD-DEM solver that leverages hybrid CPU+…
Notes on the Onset of Clustering in Gas-Solid HCS
William D. Fullmer, Xiaoqi Li, Xiaolong Yin +1
This study contributes to the body of work on instabilities in the homogeneous cooling system focusing on clustering in the multiphase gas-particle system. The critical system size…
Cluster-induced deagglomeration in dilute gravity-driven gas-solid flows of cohesive grains
Peiyuan Liu, Christine M. Hrenya
Clustering is often presumed to lead to enhanced agglomeration between cohesive grains due to the reduced relative velocities of particles within a cluster. Our discrete-particle s…
Are Continuum Predictions of Clustering Chaotic?
William D. Fullmer, Christine M. Hrenya
Gas-solid multiphase flows are prone to develop an instability known as clustering. Two-fluid models, which treat the particulate phase as a continuum, are known to reproduce the q…
Transport coefficients of solid particles immersed in a viscous gas
Vicente Garzó, William D. Fullmer, Christine M. Hrenya +1
Transport properties of a suspension of solid particles in a viscous gas are studied. The dissipation in such systems arises from two sources: inelasticity in particle collisions a…
