Locally Resolved Simulation of Gas Mixing and Combustion Inside Static and Moving Particle Assemblies

Resolving the flow field within voids between particles of reacting granular assemblies is essential to obtain correct conversion rates. Due associated computational cost, a high spatial resolution cannot be employed on device-scale. A combination locally resolving and an averaging method suggested. Namely, so-called blocked-off used resolve prescribed regions, while volume-averaged applied in remaining domain. For nitrogen jet injected into regular simple cubic packing spherical passed by cross-flow air, dispersion too low when applying for whole The same also observed methane flowing bed arbitrarily packed with air cross-flow, where resolved approach predicts significantly larger local reaction
