A CPFD simulation on the particle flow characteristics in a packed moving bed solar receiver with an added insert

Fuliang Nie et al.

Summary: The use of a downward particle flow in a quartz tube has been evaluated to eliminate particle loss associated with directly irradiated solid particle solar receivers (SPSR). A CPFD simulation showed that the thickness of the particle layer affects the distribution of axial particle velocities, with a thinner layer leading to more uniformity and higher average velocities. A thickness of 5 mm is recommended for optimal performance.

CFD Modeling and Simulation of the Hydrodynamics Characteristics of Coarse Coal Particles in a 3D Liquid-Solid Fluidized Bed

Jian Peng et al.

Summary: In this study, a Eulerian-Eulerian liquid-solid two-phase flow model combined with kinetic theory of granular flow was established to investigate the hydrodynamic characteristics and fluidization behaviors of coarse coal particles in a 3D liquid-solid fluidized bed. The simulation results agreed well with the experimental data, validating the proposed CFD mathematical model. It was found that low-density fine particles are easily fluidized, while large and heavy particles may lead to overall heterogeneity in the bed.
