Effect of particle shape on bubble dynamics in bubbling fluidized bed
نویسندگان
چکیده
Particle shape can significantly affect the bubble dynamics of bubbling fluidized beds (BFB). In this paper, findings obtained from simulations using CFD-DEM are summarized to discuss effect particle on and properties such as size, velocity at a single orifice uniform bed. Particles with aspect ratios 0.5 (oblate), 1 (spherical) 2 (prolate) employed represent disc-like, spherical rod-like particles, respectively. Both jet bed demonstrate that forming/rising regions, coalescence locations, splitting phenomena influenced by shape. The results for size show good agreement literature correlations.

Effect of Distributor Shape on Gas-Solid Bubbling Fluidized Bed Reactor
This work presents a computational study of flow behaviour in a bubbling fluidized bed polymerization reactor. The model is developed by using the commercial CFD code Fluent 6.3. The model is based on an Eulerian description of the gas and the particle phase. The effect of distributor shape on fluidization is analyzed using the inbuilt Gidaspow and Syamlal-O’brien Drag Model. The computational ...
متن کاملExperimental Study of Effects of Particle Size Distribution on Bubble Behavior for Validation of Cfd Modeling of Bubbling Fluidized Bed
The efficiency of fluidized bed reactors depends on bubble distribution, bubble size and bubble velocity within the reactor. The sizes and size distributions of particles used in the bed may lead to different bubble behaviour. The objective of this work is to study the influence of particle size distribution on bubble behaviour. The results from the experiments will be used for validation of CF...
متن کاملFundamental Bubbling Characteristics in a Rotating Fluidized Bed: Modeling and Measurement of Bubble Size
Modeling and measurement of bubble size in a rotating fluidized bed (RFB) were conducted. The model for predicting the bubble growth in RFB has been proposed based on the following concepts: (i) local centrifugal acceleration and excess gas velocity are considered as the parameters in the radial direction, and (ii) bubble volume flow locally changes depending on the radial distance. Bubbling be...
متن کاملEffect of Segregation on the Reaction Rate of Sewage Sludge Pyrolysis in a Bubbling Fluidized Bed
The evolution of the pyrolysis of sewage sludge in a fixed and a fluidized bed was analyzed using a novel measuring technique. This original measuring technique consists of installing the whole reactor over a precision scale, capable of measuring the mass of the complete reactor with enough precision to detect the mass released by the sewage sludge sample during its pyrolysis. The inert conditi...
متن کاملParticle Injection and Mixing Experiments in a One Quarter Scale Model Bubbling Fluidized Bed
One significant factor in the operation of a fluidized bed combustor is the manner in which coal particles disperse and mix with the bed material upon entering the bed. A thermal tracing technique was used to study the mixing characteristics in a 1/4 scale model of a pressurized bubbling fluidized bed combustor. Particles cooled by liquid nitrogen are injected into the bed in the same way that ...
