CPFD Modeling of Industrial-Scale Dry Flue Gas Desulfurization Systems
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.
Effect of in-Bed Heat Exchanger on Bed Inventory Imbalance in a Pantleg CFB Design – A CFD Study
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.
A Critical Validation Study on CPFD Model in Simulating Gas–Solid Bubbling Fluidized Beds
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).
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.
