CFD for Sorbent-Based Gas Cleanup System
About This Video Gas streams from reactors such as gasifiers often have a need to ‘scrub out’ undesirable gas-phase components from the primary product gases. For a gasifier’s syngas this…
Controlling dipleg returns with multiple particle species
In a hypothetical reactor vessel, particles are separated from the gas via cyclones and returned through diplegs. In Barracuda VR, this is typically done through a Pressure BC measuring the…
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.
