Instabilities in a Liquid-Fluidized Bed of Gas Bubbles
Physical Review Letters, 2000 Gas bubbles in an aqueous foam can be unjammed, or fluidized, by introducing a forced flow of the continuous liquid phase at a sufficiently high rate. We observe that the resulting bubble dynamics are spatially inhomogeneous, exhibiting a sequence of instabilities vs increasing flow rate.

Vaporization Dynamics of a Volatile Liquid Jet on a Heated Bubbling Fluidized Bed
FluidsIn this paper, droplet vaporization dynamics in a heated bubbling fluidized bed was studied. A volatile hydrocarbon liquid jet comprising acetone was injected into a hot bubbling fluidized bed of Geldart A-type glass ballotini particles heated at 150 °C,

South African Journal of Chemical Engineering, 2023 Air distribution is the primary factor that influences the performance of fluidized beds. To understand the hydrodynamics and operation of a fluidized bed, an assessment of the airflow and its distribution is essential.

Chemical Engineering Research and Design, 2019 Abstract An efficient design and operational control of a fluidized bed reactor relies on accurate prediction of bubble properties. This paper employs measurement of bed void fraction in determining the bubble velocity in a given bed. An analytical model is developed for bubble rise velocity, which shows that the rise velocity of a single bubble is ...

Particle-fluid dynamics and solid ejection in fluidized beds [PDF]
, 2008 Los flujos multifásicos son, en general, difíciles de modelar. En concreto, los lechos fluidizados burbujeantes son incluso más complejos debido a la presencia de burbujas (aparte de las partículas y de la corriente principal del gas) que aparecen cuando

Experimental Quantification of the Lateral Mixing of Binary Solids in Bubbling Fluidized Beds
Energies, 2021 A novel experimental method for the lateral mixing of binary solids in bubbling fluidized beds was developed based on the capacitance probe technique. The evolutions of local mixing ratios in a fluidized bed which can be assumed as one mixing cell were ...
