Application of Multiphase Flow Computational Dynamics to Real Process Challenges: Thien Cyclone
A novel solids separator for a chemical looping reactor was designed at NETL using Barracuda Virtual Reactor, and the final as-built separator performed well.
Modeling on the Hydrodynamics of Pressurized High-Flux Circulating Fluidized Beds (PHFCFBs) by Eulerian–Lagrangian Approach
A novel Eulerian–Lagrangian approach based on the multi-phase particle-in-cell (MP-PIC) methodology was applied in the simulation of the hydrodynamic behavior of pressurized high-flux circulating fluidized beds (DHFCFBs), and the sensitivities of key models and modeling parameters on the predictions were tested systematically.
Simulation and Optimization of the Steam Gasification Process using CPFD
This paper demonstrates that Barracuda Virtual Reactor is well suited for simulating dense particle laden fluids present in steam gasification systems due to its numerical solving methods for both the particles and the fluid.
A New Blended Acceleration Model for the Particle Contact Forces Induced by an Interstitial Fluid in Dense Particle/Fluid Flows
O’Rourke and Snider present a new contact force model where individual particle accelerations are a blend between the particle acceleration of the original MP-PIC method, appropriate for rapid granular flows, and an average particle acceleration that applies to closely packed granular flows.
Modelling and Experimental Investigation of the Full-Loop Gas–Solid Flow in a Circulating Fluidized Bed with Six Cyclone Separators
In this paper a CPFD model is combined with ECT measurements to investigate the hydrodynamic behavior in a CFB boiler with six cyclones.
Three Dimensional Kinetic Modeling of Fluidized Bed Biomass Gasification
In this study by Loha, Chattopadhyay, and Chatterjee, simulated gas compositions are found to be in good agreement with experimental data for a bubbling fluidized bed biomass gasifier.
CFD Model for the Simulation of Chemical Looping Combustion
Dr. James Parker of CPFD Software demonstrates how Barracuda Virtual Reactor can be used to develop a full three-dimensional model of a chemical looping combustion system and simulate the particle–fluid hydrodynamics, thermal characteristics, and reaction efficiency.
An Acoustic Method for the Measurement of Minimum Fluidization and Bubbling Properties of Group A Solids
Minimum fluidization and bubbling densities and velocities are widely used in fluidized bed design and modeling. The methods presently used for measuring these parameters are, however, time consuming and labor intensive.
Fluid bed characterization using Electrical Capacitance Volume Tomography (ECVT), compared to CPFD Software’s Barracuda
Four models created using Barracuda Virtual Rector are compared with results from an Electrical Capacitance Volume Tomography (ECVT) sensor and from high speed pressure measurements.
