• 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 ...
    • State of the art in mapping schemes for dilute and dense Euler-Lagrange simulations 

      Radl, Stefan; Gonzales, Begona C.; Goniva, Christoph; Pirker, Stefan (SINTEF Proceedings;1, Chapter; Conference object, 2015)
      Euler-Lagrange (EL) simulations are an extremely important tool for academia and industry to better understand gas-particle flows. We present simulation results for various gas-particle flow configurations using a variety ...
    • 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) ...
