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 …

This review article aims to provide a comprehensive and understandable account of the
theoretical foundation, modeling issues, and numerical implementation of the Lagrangian …

Gas–solid momentum transfer is a fundamental problem that is characterized by the
dependence of normalized average fluid–particle force F on solid volume fraction ϕ and the …

Gas-solid flows in nature and industrial applications are characterized by multiscale and
nonlinear interactions that manifest as rich flow physics and pose unique modeling …

Starting from a kinetic theory (KT) model for monodisperse granular flow, the exact Reynolds-
averaged (RA) equations are derived for the particle phase in a collisional fluid–particle …

This paper reviews the use of direct numerical simulation (DNS) models for the study of
mass, momentum and heat transfer phenomena prevailing in dense gas–solid flows. In …

Multiphase flows occurring in nature and in technological applications are often turbulent.
The large range of length scales and timescales in turbulent multiphase flows makes direct …

The purpose of this work is to develop gas–solid heat transfer models using Particle-
resolved Direct Numerical Simulations (PR-DNS). Gas–solid heat transfer in steady flow …

Multiphase chemical reactors with characteristic multiscale structures are intrinsically
discrete at the elemental scale. However, due to the lack of multiscale models and the …

Direct numerical simulation results for gas flow through dynamic suspensions of spherical
particles is reported. The simulations are performed using an immersed boundary method …
