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 ... -
CFD SIMULATIONS OF AN ADDITIONAL H2 COMBUSTOR FOR IMPROVING EFFICIENCY IN CHEMICAL LOOPING COMBUSTION POWER PLANTS
Scharff, Tijmen; Cloete, Schalk; Cloete, Jan Hendrik; Bastiaans, Rob (SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Chemical looping combustion (CLC) is a promising technology for hydrocarbon fuel combustion with integrated CO2 capture. The CLC process imposes almost no direct energy penalty for separating CO2, but a large indirect ... -
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 ... -
Energy-Intensive Industry as a Practical and Cost-Effective Vector for Blue Hydrogen Exports – A Norwegian Case Study
Cloete, Schalk; Cloete, Jan Hendrik (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)As political will gathers behind the ideal of rapid decarbonization, the future looks increasingly dim for oil & gas exporters. CCS offers a pathway for continued operation in the longer-term as the world decarbonizes, ... -
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) ...
