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 …

In the last decade, a few of the early attempts to bring CFD-DEM of fluidized beds beyond
the limits of small, lab-scale units to larger scale systems have become popular. The …

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 …

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

Fluid–solid systems play a major role in a wide variety of industries, from pharmaceutical
and consumer goods to chemical plants and energy generation. Along with this variety of …

This study presents conventional and artificial neural network‐based data‐driven modeling
(DDM) methods to model simultaneously the filtered mesoscale drag, heat transfer and …

Abstract Design, scale-up and operation of cyclone gas–solid separators are mostly based
on simplified models and experience. Previous single-phase or one-way coupled …

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 …

Computational fluid dynamics coupled with discrete element method (CFD‐DEM) has been
widely used to understand the complicated fundamentals inside gas–solid fluidized beds. To …

Simulations of large-scale gas-particle flows using coarse meshes and the filtered two-fluid
model approach depend critically on the constitutive model that accounts for the effects of …
