Effects of particle‐phase turbulence in gas‐solid flows
TL;DR: In this paper, a mathematical model is developed that incorporates two mechanisms that give rise to the lateral segregation of solids: interactions associated with individual particles based on a kinetic theory treatment and interaction associated with collections of particle based on an analogy with single-phase turbulent flows.
Journal ArticleDOI
Comparison of soft-sphere models to measurements of collision properties during normal impacts
A.B. Stevens,Christine M. Hrenya +1 more
TL;DR: In this paper, a comparison between model predictions and experimental data was made for soft-sphere models with and without adjustable parameters, and it was shown that the model predictions match the experimental values of restitution coefficient and collision duration obtained at an intermediate impact velocity.
Journal ArticleDOI
Enskog theory for polydisperse granular mixtures. I. Navier-Stokes order transport.
TL;DR: In this first part of the two-part series, the macroscopic balance equations for mass, momentum, and energy are derived and constitutive equations are calculated by a Chapman-Enskog expansion carried out to first order in spatial gradients, thereby resulting in a Navier-Stokes order theory.
Journal ArticleDOI
The Clustering Instability in Rapid Granular and Gas-Solid Flows
TL;DR: This review focuses on three key areas: (a) state-of-the-art mathematical tools used to study clustering, with an emphasis on kinetic theory–based continuum models, which are critical to the prediction of the larger systems found in nature and industry, and (b) mechanisms that give rise to clustering.
Journal ArticleDOI
Enskog kinetic theory for monodisperse gas–solid flows
TL;DR: In this article, the Langevin equation is used to model the gas-phase contribution to the instantaneous particle acceleration appearing in the Enskog equation, which can be applied to a wide parameter space (e.g. high Reynolds number).
