Get PriceThe 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.
Get Price2021-11-1 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.

The work examines the effect of the particle flow on the mixing characteristics of binary fluid beds with different particle properties and the impact of the presence of geometric interventions.
Get Price2021-9-1 Abstract In this work, a recent smoothed CFD-DEM model is employed to study the segregation and mixing behaviours in a bi-disperse solid–liquid fluidised bed (SLFB) with different superficial liquid velocities and wide size ratios. Here, the poly-disperse drag model is applied, and its validity and advantage are confirmed. Besides, the qualitative and quantitative characteristics are ...
Get Price2019-1-24 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 ...
