Positron emission particle tracking (PEPT) is a technique which allows the high-resolution,
three-dimensional imaging of particulate and multiphase systems, including systems which …

Circulating fluidised beds (CFBs) are developed for clean coal combustion and coal
gasification, and they play an important role in power generation. With the increase in …

Because of the importance of multiphase flows in a wide variety of industries, including
power, petroleum, and numerous processing industries, an understanding of the behavior …

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 …

A frictional–kinetic rheological model for dense assemblies of solids in a gas–particle
mixture is described. This model treats the kinetic and frictional stresses additively. The …

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 …

In the computational fluid dynamics (CFD) modeling of gas–solids two-phase flows, drag
force is the only accelerating force acting on particles and thus plays an important role in …

Fluidised beds are commonly used in the pharmaceutical industry for granulation, drying
and coating of powder or pellets. The product quality strongly depends on the operation of …

The influence of the solid-phase wall boundary condition was investigated in Eulerian–
Eulerian numerical simulations of a bubbling fluidized bed. Parametric studies of the particle …

The fluid, particle and collision dynamics inside a fluidised bed granulator are described in
detail using coupled DEM-CFD simulations. Three different granulator configurations are …
