Gas-solid fluidized beds have drawn the attention of engineers and researchers as an
effective technology for a large variety of applications, and numerical simulations can play …

Gas-solid fluidization technology has been commercialized in many industrial applications
since its implementation in the fluid catalytic cracking process in the early 1940s, however …

Starting from a kinetic theory based two‐fluid model for gas‐particle flows, we first construct
filtered two‐fluid model equations that average over small scale inhomogeneities that we do …

Due to computational time limitations, fully resolved simulations using the two‐fluid model of
the flow inside industrial‐scale fluidized beds are unaffordable. The filtered approach is …

Gas–solid two-phase flow in CFB risers is characterized by the clustering of solid particles
producing dynamical multi-scale structures, and how to quantify such heterogeneity is a …

Euler–Euler two-phase model simulations are usually performed with mesh sizes larger than
the small-scale structure size of gas–solid flows in industrial fluidised beds because of …

An EMMS/bubbling model for gas–solid bubbling fluidized bed was proposed based on the
energy-minimization multi-scale (EMMS) method (Li and Kwauk, 1994). In this new model …

Filtered two-fluid model (fTFM) for gas-particle flows require closures for the sub-filter scale
corrections to interphase drag force and stresses, the former being more significant. In this …

Abstract The Energy Minimization Multi-Scale (EMMS) drag model, using Sauter mean
particle diameter to represent real particle size distribution, has proven to be effective in …

Although great progress has been made in modeling the gas fluidization of Geldart B and D
particles and dilute gas− solid flow by standard Eulerian approach, researchers have shown …
