Mapping the operating performance of a novel internally circulating fluidized bed reactor applied to chemical looping combustion
Chemical looping combustion is a promising technology for minimizing the energy penalty of CO2 capture. To accelerate the scale-up and commercialization of this technology for pressurized operation, the internally circulating reactor (ICR) was recently proposed. ICR integrates the two reactors, cycl...

The oxygen production pre-combustion (OPPC) IGCC plant for efficient power production with CO2 capture
Chemical looping combustion in an internally circulating fluidized-bed reactor operated with a CaMnO3-δ-based oxygen carrier
Efficiency Improvement of Chemical Looping Combustion Combined Cycle Power Plants
Simulation-Based Design and Economic Evaluation of a Novel Internally Circulating Fluidized Bed Reactor for Power Production with Integrated CO2 Capture
Limiting global temperature rise to well below 2 °C according to the Paris climate accord will require accelerated development, scale-up, and commercialization of innovative and environmentally friendly reactor concepts. Simulation-based design can play a central role in achieving this goal by ...
Towards rigorous multiscale flow models of nanoparticle reactivity in chemical looping applications
A multiscale modeling framework is described and applied to the reactivity of iron oxide nanoparticles in a chemical looping reforming (CLR) reactor. At the atomic scale/nanoscale, we have performed kinetic Monte Carlo modeling, guided by Density Functional Theory calculations, on the detailed kinet...
On the choice of closure complexity in anisotropic drag closures for filtered Two Fluid Models
Filtered Two Fluid Models (fTFMs) aim to enable accurate industrial-scale simulations of fluidized beds by means of closures accounting for the effects of bubbles and clusters. The present study aims to improve anisotropic closures for the drift velocity, which is the primary sub-grid effect alterin...
