Application of Recent CFD Advancements to the Modeling of Chemical Looping Systems
With recent advancements in CFD modeling tools, chemical looping simulations can be more accurate and efficient than what was possible just a few years ago, in large part due to increases in model calculation rates afforded by improved computing hardware and improved parallelization of CFD software. In this work, the impact of these improvements is assessed using a chemical looping reactor model as a benchmark.
