This paper uses digital image analysis of two-dimensional fluidized beds to establish a relationship between gas velocity and both bubble shape factor distribution and bubble aspect ratio distribution.
Examples showing the application of ‘Labasys® instruments’ in R&D and production monitoring are provided for illustration in this article.
This paper reviews existing image reconstruction algorithms for ECT, including linear back-projection, singular value decomposition, Tikhonov regularization, Newton–Raphson, iterative Tikhonov, the steepest descent method, Landweber iteration, the conjugate gradient method, algebraic reconstruction techniques, simultaneous iterative reconstruction techniques and model-based reconstruction.
In this paper, Dale Snider presents the MP-PIC method, the Eulerian-Lagrangian method upon which Barracuda Virtual Reactor is based, for dense particle flow.
Explicit equations are developed for the drag coefficient and for the terminal velocity of falling spherical and non-spherical particles.
Inclined, intermittent jets can be used to feed solids into fluidized beds. In this report the injection system was successfully modeled.
Non-mechanical valves, especially the L-valves, have been used extensively in fluidized beds and circulating fluidized beds for solids recycling or to serve as a pressure seal. This paper presents a set of L-valve equations which relate the solids flow rate to the L-valve design, aeration rate, and pressure drop across the L-valve.
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.
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.
