Three cases are presented on the entrainment of various materials from fluidized beds in which agglomerated clumps of particles affected the measured entrainment rates. Evidence suggests that fine particles in many materials may be clumping together – resulting in a reduced entrainment rate.
Gas streaming is the severe bypassing of gas that can occur in deep, bubbling fluidized beds. Gas bypassing consists of a large jet that precesses around the walls of the fluidized bed. Details of possible mechanisms and possible techniques for detecting gas-bypassing are presented in this report.
The development of the multi-phase flow algorithm MIPSA (Multi-InterPhase Slip-Algorithm) within a two-dimensional Computational Fluid Dynamics (CFD) code called CASCADE is summarized with its application to the modeling of lean phase circulating fluidized beds
In this publication, typical commercial stripper operating problems are pointed out, and methods to diagnose the problems are identified.
This paper documents the development of electrical capacitance volume tomography.
In this paper by Dale M. Snider, granular flow of three granular flow experiments is predicted by a CPFD numerical scheme in three dimension using the true particle size distribution.
Extensive lattice-Boltzmann simulations were performed to obtain the drag force for random arrays of monodisperse and bidisperse spheres.
Cyclones have been in operation for over one hundred years. Arena-Flow simulations were preformed to understand the gas hydrodynamics in a commercial scale cyclone and its implication towards both gas distribution and residence time.
This paper demonstrates a correlation between in-bed pressure fluctuations and information about bubble size distribution for Geldart A and B powders.
The kinetic model in this paper is based on a molecular approach and is proposed to represent the cracking reactions of industrial feedstocks on a commercial equilibrium catalyst; given that it shows the importance of the condensation and hydrogen transfer reactions for coke formation and gasoline quality, it therefore can be used for modeling a commercial FCC riser.
