Jet Cup Attrition Testing
This paper by Particulate Solid Research, Inc (PSRI) discusses jet cup attrition testing, and how CFD such as Barracuda Virtual Reactor can be used to improve jet cup design.
Effect of gas bypassing in deep beds on cyclone dipleg operation
Cyclone diplegs play a major role in the functioning of fluidized beds. Previous studies. This report discusses tests conducted to demonstrate that cyclone diplegs can flood when discharging into a bed with gas bypassing.
The Effect of Cohesive Forces on Catalyst Entrainment in Fluidized Bed Regenerators
Clustering of particles in granular-fluid systems has been known to exist for some time. Wilhelm and Kwauk were among the first to show evidence of particle clustering in fluidized beds with others following suit with similar experiments.
Effects of imposed solids flux and pressure on gas bypassing in deep fluidized beds of Group A materials
Tests were conducted in 0.6-m and 0.9-m-diameter units to determine the effect of imposed solids flux and system pressure on gas bypassing in deep beds of FCC catalyst particles.
CFD Modeling and X-Ray Imaging of Biomass in a Fluidized Bed
In this paper, computational modeling of fluidized beds is used to predict the operation of biomass gasifiers after extensive validation with experimental data, and hydrodynamic results from the simulations were compared with X-ray flow visualization computed tomography studies of a similar bed.
Three-Dimensional Simulation of Liquid Injection, Film Formation and Transport, in Fluidized Beds
This paper presents new capabilities and proof-testing of a collisional model previously presented in O’Rourke, Zhao, and Snider (2009) applied to liquid injection into a dense-phase fluidized bed.
Heterogeneous Gas Chemistry in the CPFD Eulerian–Lagrangian Numerical Scheme (Ozone Decomposition)
Researchers from CPFD and Cristal Global present a solution of ozone decomposition in a bubbling bed using the CPFD numerical scheme. Results compared well with the experimental data reported by Fryer and Potter (1976).
Maximum entropy estimation of the bubble size distribution in fluidized beds
This work presents a new methodology, based on the maximum entropy method, to obtain bubble characteristics in fluidized beds.
A Model for Collisional Exchange in Gas/Liquid/Solid Fluidized Beds
A new model is presented by O’Rourke, Zhao, and Snider for numerical simulations of collisional transfer of mass, momentum and energy in gas/liquid/solid fluidized beds.
Pressure and Temperature Effects in Fluid-Particle Systems
Most investigations of fluidization parameters take place at ambi- ent temperature and pressure. Yet, nearly all processes operate at elevated temperature, and many at elevated pressure.
