Experimental Validation of CFD Hydrodynamic Models for Catalytic Fast Pyrolysis (CFP)
Researchers at KiOR LLC working with CPFD Software staff use Barracuda Virtual Reactor to develop a Catalytic Fast Pyrolysis (CFP) technology that emulates the FCC process.
CFD Studies on Biomass Gasification in a Pilot-Scale Dual Fluidized-Bed System
A model using the MP-PIC method was developed to simulate a pilot-scale dual fluidized-bed biomass gasification system and was validated by experimental results; it was then used to investigate the impact of various changes on the producer gas composition.
CPFD Modeling and Experimental Validation of Gas–Solid Flow in a Down Flow Reactor
In this paper, a hybrid model of a gas-solid fluidized bed unit is developed using Barracuda Virtual Reactor and then is validated by experimental data.
Particle Attrition: Mechanisms and Methods to Determine Attrition Indices
Particle attrition can be a major issue in using catalyst particles in fluidized beds and circulating fluidized beds. Particles tend to break down via two mechanisms – abrasion and fragmentation.
Hydrodynamics of High Velocity Circulating Fluidized Bed Risers
In this research the solids flux measurements showed the risers having different shapes of radial profiles. The net solids flow direction at all radial locations was found to be upward for the conditions used in this study.
Use of pressure to mitigate gas bypassing in fluidized beds of FCC catalyst particles
This publication demonstrates that pressure fluctuations and local bubble void fraction can diagnose gas bypassing
Comparison of Numerical Approaches to Model FCC Particles in Gas–Solid Bubbling Fluidized Bed
The hydrodynamics of FCC particles in a bubbling fluidized bed are predicted by both Barracuda Virtual Reactor and by a CFD model, and their results were compared.
CPFD Simulation on Wear Mechanisms in Disk–Donut FCC Strippers
In this paper, three cases of Barracuda Virtual Reactor models were established to validate three speculations on wear mechanisms; the simulated locations with the highest wear magnitudes are agreeable with the wear accidents reported in industry.
Comparative study of Transport Disengaging Height (TDH) correlations in gas–solid fluidization
In this publication, Transport Disengaging Height correlations are evaluated across Geldart Groups, polydispersity and velocities.
