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.
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.
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.
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.
In this paper a CPFD model is combined with ECT measurements to investigate the hydrodynamic behavior in a CFB boiler with six cyclones.
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.
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.
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.
This video shows transient computational fluid dynamics model results for an industrial dry flue gas desulfurization system.
This video shows the transient, 3D modeling of the thermal and reacting flows inside an FCC riser located on the Arabian Peninsula.
