Fluidization behavior of biomass and glass beads binary mixtures in a bubbling fluidized
bed was experimentally investigated. Mixtures containing different mass fraction of Loblolly …

Steam-biomass gasification in a three-dimensional lab-scale spouted bed gasifier is
numerically simulated via the multiphase particle-in-cell approach. The spatial distribution of …

Via the multiphase particle-in-cell method, the gasification of biomass feedstock in a pilot-
scale dual fluidized bed gasifier is simulated to study the dynamical behavior of mesoscale …

The accuracy of coarse‐grained discrete element method (CGDEM) relies on appropriate
scaling rules for contact and fluid‐particle interaction forces. For fluidized bed applications …

Numerical simulations of a freely bubbling cylindrical fluidized bed are carried out using a
coupled computational fluid dynamics and discrete element method (CFD-DEM) model and …

Image-based velocimetry methods have become a widely used method to characterize
solids velocity fields in particulate devices; two of the most commonly used methods being …

Fluidization experiments were conducted on a small scale and with a rapid response (short
duration) to enable corresponding simulations at low‐computational cost. Rise times are …

Particle tracking methods extract high-fidelity particle-scale velocity data from digital video
measurements of particle laden flow. This experimental technique is often used to better …

MFiX-Exa is a new code being actively developed at Lawrence Berkeley National
Laboratory and the National Energy Technology Laboratory as part of the US Department of …

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 …
