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 …

As multiscale structures are inherent in multiphase flows, constitutive models employed in
conjunction with transport equations for momentum, species, and energy are scale …

Coarse-grid two-fluid simulation of gas-solid fluidized bed reactors based on the kinetic
theory of granular flow exhibits a significant dependence on drag models, especially for …

A model for predicting the behaviour of a compressible flow laden with shocks interacting
with granular material has been developed and tested. The model consists of two sets of …

Two different approaches to constitutive relations for filtered two‐fluid models (TFM) of gas–
solid flows are deduced. The first model (Model A) is derived using systematically filtered …

We present a spatially‐averaged two‐fluid model (SA‐TFM), which is derived from
ensemble averaging the kinetic‐theory based TFM equations. The residual correlation for …

Continuum modelingof granular and gas-solid flows generally involves the use of a kinetic-
theory (KT) model for the particulate phase, and the most widely used KT models have been …

Developing, verifying and validating sub-grid methods is of crucial significance for enabling
accurate coarse-grained two-fluid modeling of rapid gas-fluidized flows. However, very few …

Many subgrid drag modifications have been put forth to account for the effect of small
unresolved scales on the resolved mesoscales in dense gas‐particle flows. These subgrid …

The present work is dedicated to the numerical study of the hydrodynamics of a pressurized
fluidized-bed using an Euler–Lagrange approach, with the goal to gain insight into the Two …
