Fluidized bed has many advantages such as high heat and mass transfer rates, temperature homogeneity and good mixing property. However, conventional fluidized bed has some limitations; operation at high gas velocity leads to slugging and there exists minimum particle size for the uniform fluidization. Recently, a rotating fluidized bed (RFB) has attracted special interest, since it has a possib...

The fluidization characteristics of a prototype-fluidized bed laboratory reactor were understudied in order to investigate the suitable conditions at which the dehydrogenation reaction of butane could be carried out. To achieve this, a reactor with an effective volume of 1100ml was fabricated and coupled with temperature and pressure accessories. Zeolites were obtained from the market and clay ...

Recent experiments have investigated the response of smooth muscle cells to transient stretch-compress (SC) and compress-stretch (CS) maneuvers. The results indicate that the transient SC maneuver causes a sudden fluidization of the cell while the CS maneuver does not. To understand this asymmetric behavior, we have built a biomechanical model to probe the response of stress fibers to the two m...

Film coating of fine particles (5-20 microns) by polymers has a wide range of industrial applications, yet few techniques are commercially available that are environmentally friendly. In this study, four different techniques are considered with an ultimate goal of developing a reliable technique that is scaleable and is also environmentally friendly. Two of these techniques are fluidization bas...

ISSN 2277 5056 | © 2012 Bonfring Abstract--Fluidization is an operation in which solid particles are kept under suspension supported by the upward flow of liquid/gas phase. In classic fluidization the solids density are higher than the liquid, where as in Inverse fluidization the solids density are lower than that of continuous liquid phase. The phase holdup measurements in three phase classic/...

Liquid fluidization of mixtures solid particles spherical and cylindrical shape has been numerically simulated. The simulations explicitly resolve the solid–liquid interfaces by means an immersed boundary method implemented in a lattice-Boltzmann flow solver. A soft collision algorithm deals with particle–particle contacts close-range hydrodynamic interaction. systems studied have overall solid...

The physical parameters of two products widely used in the confectionery industry – peanuts and cocoa beans have been studied. hydrodynamic characteristics these products, influencing fluidized bed roasting regime, determined. hydrodynamics a rotating-pulsed fluidization cited materials has examined. Dependences are derived for calculating pressure drops initial velocity particles during creati...

Composite zeolites impregnated with anhydrous salt particles are promising materials for use in domestic thermochemical energy storage (TCES), however they have limited power output. Fluidization has the potential to increase mass and heat transfer of TCES systems. In this study, a composite material LiX zeolite MgCl2 is produced. This batch then fluidized at different gas velocities study whet...
