Bioreactors with Light-Beads Fluidized Bed: The Voidage Function and its Expression

Voidage Wave Instability in a Vibrated Liquid-Fluidized Bed

The Effect of Vibration on Bed Voidage Behaviors in Fluidized Beds with Large Particles

The effects of vibration parameters, operating conditions and material properties on bed voidage were investigated using an optical fiber probe approach in a vibrating fluidized bed with a diameter of 148 mm. Variables studied included frequency (0-282 s), amplitude (0 mm-1 mm), bed height (0.1 m-0.4 m) as well as four kinds of particles (belonging to Geldart's B and D groups). The axial and ra...

Bed Voidage and Heat Transfer in Non-Newtonian Liquid-Solid Fluidized Bed

The presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. Moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. The aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coeff...
