COMPARISON OF PARTICLE-RESOLVED DIRECT NUMERICAL SIMULATION AND 1D MODELLING OF CATALYTIC REACTIONS IN A PACKED BED
Singhal, Arpit; Cloete, Schalk Willem Petrus; Radl, Stefan; Quinta-Ferreira, Roas; Amini, Shahriar (Chapter, 2017)The work presents a comparison of catalytic gas-solid reactions in a packed bed as simulated on two widely different scales: direct numerical simulation (capable of accurately predicting transfer phenomena in and around a ... -
On the choice of closure complexity in anisotropic drag closures for filtered Two Fluid Models
Cloete, Jan Hendrik; Cloete, Schalk Willem Petrus; Radl, Stefan; Amini, Shahriar (Journal article; Peer reviewed, 2019)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 ... -
Towards rigorous multiscale flow models of nanoparticle reactivity in chemical looping applications
Andersson, Stefan; Radl, Stefan; Svenum, Ingeborg-Helene; Shevlin, Stephen; Amini, Shahriar; Guo, Xiao (Journal article; Peer reviewed, 2019)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 ... -
Verification of filtered two fluid models for reactive gas‐solid flows
Cloete, Jan Hendrik; Cloete, Schalk; Radl, Stefan; Amini, Shahriar (SINTEF Proceedings;2, Conference object; Peer reviewed, 2017)CFD simulations of fluidized bed reactors are generally limited to the laboratory scale because of the fine grid sizes that are required to resolve complex particle clustering phenomena. The filtered Two Fluid Model (fTFM) ...
