Validation of Particle Fluid Dynamic Code Using Chemical Looping Experiments

Chemical looping combustion (CLC) and chemical looping with oxygen uncoupling (CLOU) are promising carbon capture technologies. Little experimental or simulated work has been copleted on systems larger than 1 MW. A complete understanding of the hydrodynamics will result in a quicker scaling to larger systems. To understand the hydrodynamics a scaled cold-flow unit was evaluated through visualization, pressure measurements, circulation rate, and bed mass changes. To further explore the hydrodynamics of CLC and CLOU a 10 kW system was run hot and cold was evaluated through pressure measurements, circulation rate, and bed mass changes. These evaluations and experiments were compared to simulations of Barracuda-VR®. The results shows that Barracuda-VR® accuratly represents the experiments.
