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...

Numerical study of heat transfer in fluidized bed dryers by volume of fluid ‎method

The purpose of this study is numerical modeling of temperature variation of phases in a two phase regime in fluidized bed dryers including particles belonging to Group D of geldart classification. The mass transfer between phases is not taken into consideration in this modeling which has been assumed in three- dimensional, unsteady, and two-phase regime.To verify the modeling we consider the do...

Energy transfer mechanism in a vibrating fluidized bed

The mechanism of vibration energy transfer in a vibrating fluidized bed (VFB) is reported in this paper. A series of sensors was employed to simultaneously detect pressure wave propagation signals at different positions at various heights in the fluidized bed. The mechanism of vibration energy transfer in an VFB is found by wave propagation. The pressure wave was produced from a vibrating base ...

Mass transfer studies on biological denitrification in fluidized bed bioreactor.

A fluidized bed bioreactor has been used to carry out biological denitrification in the present work as it offers many advantages over other types of reactors. Plastic beads of low density (1055 kg/m3) were used as fluidizing media with Pseudomonas stuzeri, a denitrifying microorganism immobilized on them. The denitrification rate under different operating conditions was studied. The results of...
