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 …

Conventional and emerging processes that require the application of multiphase reactors
are reviewed with an emphasis on catalytic processes. In the past, catalyst discovery and …

This report describes the MFIX (Multiphase Flow with Interphase exchanges) computer
model. MFIX is a general-purpose hydrodynamic model that describes chemical reactions …

Meso-scale structures that take the form of clusters and streamers are commonly observed
in dilute gas–particle flows, such as those encountered in risers. Continuum equations for …

Gas-solid flows are involved in numerous industrial processes and occur in various natural
phenomena. This authoritative book addresses the fundamental principles that govern gas …

ing equations of Ishii 1975 do not differ from those of Anderson and Jackson 1967 in terms
of macroscopic flow beha® ior, but differ on a local scale. Flow predictions are not sensiti® e …

Starting from a kinetic theory based two‐fluid model for gas‐particle flows, we first construct
filtered two‐fluid model equations that average over small scale inhomogeneities that we do …

This paper presents an overview of the physical models for computational fluid dynamic
(CFD) predictions of multiphase flows. The governing equations and closure models are …

A theory intended for slow, dense flows of cohesionless granular materials is developed for
the case of planar deformations. By considering granular flows on very fine scales, one can …

Gas/particle flow behavior in the riser section of a circulating fluidized bed (CFB) was
simulated using a computational fluid dynamics (CFD) package by Fluent. Fluid catalytic …
