Dynamic waves in fluidized beds
Powder Technology, 1995Abstract Published results on the velocity of propagation and the change of amplitude of dynamic waves in fluidized beds are reviewed and re-evaluated. A distinction is drawn between pressure waves and solids concentration waves. Over the range of frequencies of interest in fluidized beds, predictions of the velocity of compression waves by pseudo ...

Bed Expansion – Extending Correlations for Fluidized Beds with Inserts to Open Fluidized Beds
Chemical Engineering & Technology, 2007AbstractBed expansion occurs during the operation of gas‐fluidized beds and is influenced by particle properties, gas properties and distributor characteristics. It has a significant bearing on heat and mass transfer phenomena within the bed. A method of predicting bed expansion behavior from other fluidizing parameters would be a useful tool in the ...

Minimum fluidization velocity and bed expansion of the inverse fluidized bed
Particulate Science and Technology, 2023To define the fluid-dynamic properties of inverse fluidized beds, studies of the minimum fluidization velocity and bed expansion were performed in this work. The experiments were performed in an inverse fluidized bed of polypropylene and polystyrene particles in a cylindrical column using water and an aqueous glycerol solution of different ...

Fluidization and Fluidized Bed
2019This chapter introduces a multiscale method for modeling gas–solid flows, from steady-state modeling for quick engineering design, continuum model for industrial scale reactor simulation, discrete particle method for lab-scale reactor simulation to direct numerical simulation for exploring the underlying mechanics.
