Determination of Cluster Hydrodynamics in Bubbling Fluidized Beds by the EMMS Approach
Journal of Chemical and Petroleum Engineering, 2011 The local solid flow structure of gas-solid bubbling fluidized bed was investigated to identify and characterize the particle clusters. Extensive mathematical calculations were carried out using the energy-minimization multi-scale (EMMS) approach for ...

Effect of bed size on hydrodynamics in 3‐D gas–solid fluidized beds
AIChE Journal, 2015 It is well known that hydrodynamics observed in large scale gas–solid fluidized beds are different from those observed in smaller scale beds. In this article, an efficient two‐fluid model based on kinetic theory of granular flow is applied, with the goal to highlight and investigate hydrodynamics differences between three‐dimensional fluidized beds of ...

PARTICLE MOVEMENT IN A GAS-SOLID FLUIDIZED BED
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1968 The photographs of particle movement were taken in a two-dimensional fluidized bed and statistically analyzed. The circulation of the solid phase was proved to exist from the mean particle velocity and the scale of movement concerning space and time was obtained from the autocorrelation coefficient of particle velocity.
