CFD-DEM study on the mixing characteristics of binary ...

The fluidization of quartz in the fluidized bed has great influence on the combustion and gasification of refuse-derived fuel (RDF). The combined computational fluid dynamics (CFD) and discrete element method (DEM) approach was used to explore the gas-solid hydrodynamics and mixing characteristics in a three-dimensional fluidized bed.

CFD-DEM study of segregation and mixing characteristics ...

2021-11-1  Table 1 summarises the detailed simulation conditions of above CFD-DEM studies on the binary SLFB systems. From these studies, it can be noted that the complex mixing behaviours in the transition zone where the two species mix are important but still unclear, and the underlying mechanism of segregation and mixing behaviours in the binary SLFB systems hasn’t been well unveiled.

CFD-DEM modelling of mixing and segregation of binary ...

2019-1-24  Solid-liquid fluidized beds of binary mixtures are widely used in many industries. Particle segregation may occur as particles can differ in size, density, or shape. Extensive studies have been conducted in the past to understand the effects of particlesize and density on the mixing and segregation, but the effect of particle shape has not been well addressed. Therefore, in the present work ...

Mixing and Segregation Characteristics of Binary

2013-12-24  The mixing and segregation in classical and tapered fluidized beds is reported [11]. This is based on the re- views [12]. It is well known that mixing degree of solids in a bi- nary fluidized bed with a constant cross-section is always between extremes, i.e. complete separation and complete mixing of the solid phases. Completely separated binary
