    • 1-D phenomenological modelling of gas-solid fluidized bed reactors for chemical looping reforming 

      Morgado, Joana Francisco (Doctoral theses at NTNU;2018:9, Doctoral thesis, 2018)
      This PhD thesis is a part of the EU FP7 Project called NanoSim. The main objective of this work is to develop a 1-D phenomenological model for fluidized bed reactors to simulate the performance of second-generation CO2 ...

    • 1D modelling of membrane-assisted chemical looping reforming 

      Francisco Morgado, Joana; Cloete, Schalk Willem Petrus; Morud, John; Gurker, Thomas; Quinta-Ferreira, Rosa; Amini, Shahriar (Journal article; Peer reviewed, 2017)
      Membrane-assisted chemical looping reforming (MA-CLR) has been proposed as an alternative to the conventional CLR technology. In this work, a non-isothermal 1D model is used to simulate the MA-CLR fuel reactor. The effect ...

    • 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 ...

    • Techno-economic assessment of chemical looping reforming of natural gas for hydrogen production and power generation with integrated CO2 capture 

      Nazir, Shareq Mohd; Francisco Morgado, Joana; Bolland, Olav; Quinta-Ferreira, Rosa; Amini, Shahriar (Journal article; Peer reviewed, 2018)
      The current study presents the techno-economic analysis of the CLR-CC process. The CLR-CC process comprises of chemical looping reforming (CLR) of Natural Gas, water gas shift, CO2 capture and compression, and combined ...

    • 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 ...
