Accurate predictions of both the flux and size distribution of the solids entrained above the transport disengaging height of a fluidized bed are necessary. A new correlation was developed to calculate size distribution and flux of entrained particles.
This presentation by Dr. Kit Windows-Yule at the 2022 Barracuda Virtual Reactor Users’ Conference discusses data validation methods for waste plastic pyrolysis, a system that efficiently converts plastic waste into petrochemical fuels.
In this paper, to investigate the effects of particle properties on these meso-scale structures, for all particle types, two-fluid modeling with and without consideration of meso-scale structures were performed and compared.
Gas/particle flow behavior in the riser section of a circulating fluidized bed (CFB) was simulated using a computational fluid dynamics (CFD) package by Fluent. Gas and particle flow profiles were obtained for velocity, volume fraction, pressure, and turbulence parameters for each phase.
This presentation by Scott Fowler demonstrates the use of Tecplot 360, PyTecplot and Tecplot’s Add-on Developer Kit to perform advanced analysis of results from Barracuda.
In this work, a selection of widely used correlations have been critically evaluated for estimating the drag coefficient of non-spherical particles in incompressible viscous fluids.
The flow of gas—particle mixtures in a circulating fluidized bed has been studied, probing the flow behavior under both stable and unstable operating conditions.
This presentation by James Parker of CPFD Software discusses the history of Barracuda’s development as well as new and ongoing developments such as Multi-GPU support and VLS systems.
Chemical Reaction Engineering, Third Edition, by Octave Levenspiel, helps students learn how to answer reactor design questions reliably and effectively.
Although chemistry is the initial driving force for the development of chemical processes, in many instances the key to successful process operation is how well the solids transport systems have been designed. This is especially true in circulating fluidized bed (CFB) processes, because these processes are dependent upon rapid and reliable circulation of solids.
