Bigda, from the Institute for Chemical Processing of Coal (IChPW), Poland, presents CPFD numerical studies of the hydrodynamics of gas-solid flow and the drying process using Barracuda Virtual Reactor.
In this paper a CPFD model for dry flue gas desulfurization (DFGD) systems was developed, validated against lab-scale data, and applied to an industrial-scale unit.
In this paper presented at CFB-11, a team from Babcok & Wilcox Power Generation Group report on Barracuda simulations of a large capacity, pantleg CFB boiler.
To demonstrate the strengths and weaknesses of Barracuda Virtual Reactor, a model of a pseudo-2D fluidized bed created using it is compared to a two-fluid model (TFM).
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.
