Acoustic Field Effects on Minimum Fluidization Velocity in a 3d Fluidized Bed
Fluidized beds are used in a variety of process industries because they provide uniform temperature distributions, low pressure drops, and high heat/mass rates. Minimum fluidization velocity is an important factor in understanding the hydrodynamic behavior of fluidized beds, and this characteristic may be modified through high frequency (sound) vibrations. The effects caused by sound wave frequ...
متن کاملHydrodynamic Studies of Fluidized Bed Chemical Vapor Deposition Reactors to Produce Carbon Nano Tubes via Catalytic Decomposition over Co/Pd MgO
The hydrodynamic studies of fluidized bed reactor has been reported in terms of pressure drop, minimum fluidization velocity and bed volume expansion to contribute to the optimization of the CNTs production parameters in fluidized bed reactors. Minimum fluidization velocity and pressure drop, as the most important parameters, were taken into account for the investigation of the hydrodynamic beh...
متن کاملFluidization Characteristics of a Prototype Fluidized Bed Reactor
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 ...
متن کاملCFD Modeling of TiO2 Nano-Agglomerates Hydrodynamics in a Conical Fluidized Bed Unit with Experimental Validation
In the computational fluid dynamics (CFD) modeling of gas-solids two phase flow, the effect of boundary conditions play an important role in predicting the hydrodynamic characteristics of fluidized beds. In this work, the hydrodynamics of conical fluidized bed containing dried TiO2 nano-agglomerates were studied both experimentally and computationally. The pressure drop ...
متن کاملFundamental Particle Fluidization Mechanism and Handling of Fine Particles in a Rotating Fluidized Bed
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...
