    • 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 ...

    • Heat and mass transfer in gas-solid packed beds 

      Singhal, Arpit (Doctoral theses at NTNU;2018:137, Doctoral thesis, 2018)
      The present thesis probes the heat and mass transfer phenomena in packed bed of particles. The gap in literature for realistically packed dense particle packings is explored, following which a new methodology to study ...

    • Multiscale modelling of packed bed chemical looping reforming 

      Singhal, Arpit; Cloete, Schalk Willem Petrus; Quinta-Ferreira, Rosa; Amini, Shahriar (Journal article; Peer reviewed, 2017)
      A comparison of reactive flows on two distinct scales is presented here (i) Particle resolved direct numerical simulation (PR-DNS), and (ii) 1D packed bed model. The PR-DNS geometry is meshed with polyhedral elements both ...

    • Verification of heat and mass transfer closures in industrial scale packed bed reactor simulations 

      Singhal, Arpit; Cloete, Schalk Willem Petrus; Quinta-Ferreira, Rosa; Amini, Shahriar (Journal article; Peer reviewed, 2018)
      Particle-resolved direct numerical simulation (PR-DNS) is known to provide an accurate detailed insight into the local flow phenomena in static particle arrays. Most PR-DNS studies in literature do not account for reactions ...
