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 …

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

Three Ni-based natural gas steam reforming catalysts, ie, commercial JM25-4Q and JM57-
4Q, and a laboratory-made catalyst (26% Ni on a 5% SiO2–95% Al2O3), are tested in a …

The Multiphase Flow Handbook, Second Edition is a thoroughly updated and reorganized
revision of the late Clayton Crowe's work, and provides a detailed look at the basic concepts …

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 …

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 …

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 …

In this work, we present a rigorous derivation of the volume-filtered viscous compressible
Navier–Stokes equations for disperse two-phase flows. Compared to incompressible flows …

Abstract The Immersed Boundary (IB) method proposed by Uhlmann for Direct Numerical
Simulation (DNS) of fluid flow through dense fluid-particle systems is extended to systems …

Gas-phase velocity fluctuations due to mean slip velocity between the gas and solid phases
are quantified using particle-resolved direct numerical simulation. These fluctuations are …
