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 …

The combination of Computational Fluid Dynamics (CFD) and Discrete Element Model
(DEM) is a powerful tool for studying fluidized particulate systems and granular flows. In …

Understanding the hydrodynamics of gas–solid flows is a grand challenge in mechanical
and chemical engineering. The continuum-based two-fluid models (TFM) are currently not …

New constitutive relations for filtered two‐fluid models (TFM) of gas‐particle flows are
obtained by systematically filtering results generated through highly resolved simulations of …

This article reviews the general features of the multiscale structures in particle–fluid systems
and the characterization, modeling, and simulation methods for these systems. The …

Circulating fluidized beds (CFBs) have been widely applied in coal combustion and
gasification industry due to their excellent performance in terms of fuel flexibility and …

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 …

Abstract Eulerian–Eulerian and Eulerian-Lagrangian numerical approaches are both widely
used to investigate hydrodynamic behavior in dense gas-solid fluidized bed reactors, yet …

Virtual process engineering (VPE) aims to redefine the roadmap for process scaling-up and
optimization, from stepwise experiments to high-performance computer simulations. This is a …
