A multi-scale model for oxygen carrier selection and reactor design applied to packed bed chemical looping combustion
Tabib, Mandar; Morud, John; Johansen, Stein Tore; Amini, Shahriar (SINTEF Proceedings;1, Chapter, 2015)Proper selection of a catalyst shape (or a particle shape) can improve the performance of a gas-solid packed bed reactor. The particle shape affects the packing structure and the transport phenomena within the packed bed. ... -
A multi‐domain 1D particle‐reactor model for packed bed reactor applications
Tabib, Mandar; Cloete, Schalk; Morud, John; Lysberg, Magne; Amini, Shahriar (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)A validated multi-domain 1D particle-reactor model has been developed to simulate packed bed reactor operation. Two main components of the model are: (1) a particle model for simulating the radial distribution of chemical ... -
Comparison of particle‐resolved direct numerical simulation and 1D modelling of catalytic reactions in a packed bed
Singhal, Arpit; Cloete, Schalk; Radi, Stefan; Quinta-Ferreira, Rosa; Amini, Shahriar (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 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 ... -
Hydrodynamic investigation into a novel IC-CLC reactor concept for power production with integrated CO2 capture
Zaabout, Abdelghafour; Cloete, Schalk; Amini, Shahriar (SINTEF Proceedings;1, Chapter; Conference object; Peer reviewed, 2015)This paper presents an investigation of the hydrodynamics of a new Chemical Looping Combustion (CLC) reactor concept for power generation with integrated CO2 capture. This concept consists of an internal circulating fluidized ... -
The parametric sensitivity of fluidized bed reactor simulations carried out in different flow regimes
Cloete, Schalk; Cloete, Jan H.; Johansen, Stein Tore; Amini, Shahriar (SINTEF Proceedings;1, Chapter; Conference object; Peer reviewed, 2015)Fluidized bed simulations carried out within the Kinetic Theory of Granular Flows framework utilize a number of model coefficients which are strongly case dependent and difficult to determine accurately. The most important ... -
Verification of filtered two fluid models for reactive gas‐solid flows
Cloete, Jan Hendrik; Cloete, Schalk; Radl, Stefan; Amini, Shahriar (SINTEF Proceedings;2, Chapter; 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) ...
