CFD-DEM simulation of biomass gasification with steam in a fluidized BEd reactor
Ku, Xiaoke; Li, Tian; Løvås, Terese (Journal article; Peer reviewed, 2015)A comprehensive CFD–DEM numerical model has been developed to simulate the biomass gasification process in a fluidized bed reactor. The methodology is based on an Eulerian–Lagrangian concept, which uses an Eulerian method ... -
CFD-DEM simulation of biomass pyrolysis in fluidized-bed reactor with a multistep kinetic scheme
Chen, Tao; Ku, Xiaoke; Lin, Jian-Zhong; Strøm, Henrik (Peer reviewed; Journal article, 2020)The pyrolysis of biomass in a fluidized-bed reactor is studied by a combination of a CFD-DEM algorithm and a multistep kinetic scheme, where fluid dynamics, heat and mass transfer, particle collisions, and the detailed ... -
Detailed operational mapping of a grate fired Biomass combustion plant for improved combustion process control
Khalil, Roger Antoine; Malik, Azhar; Ku, Xiaoke; Skreiberg, Øyvind; Fossum, Morten; Becidan, Michael; Løvås, Terese (Journal article; Peer reviewed, 2016)Biomass combustion plants in Norway are facing stricter emission regulations and lower profitability, mostly due to low energy prices. Hence, performance optimization through improved combustion process control and/or ... -
Eulerian–Lagrangian Simulation of Biomass Gasification Behavior in a High-Temperature Entrained-Flow Reactor
Ku, Xiaoke; Li, Tian; Løvås, Terese (Journal article; Peer reviewed, 2014)In this paper, a multiscale Eulerian–Lagrangian CFD model based on OpenFOAM has been constructed, which takes into account heat and mass transfer, pyrolysis, homogeneous and heterogeneous reactions, radiation, as well as ... -
High-temperature pyrolysis modeling of a thermally thick biomass particle based on an MD-derived tar cracking model
Chen, Tao; Ku, Xiaoke; Li, Tian; Karlsson, Bodil S.A.; Sjöblom, Jonas; Strøm, Henrik (Peer reviewed; Journal article, 2021)Biomass pyrolysis in the thermally thick regime is an important thermochemical phenomenon encountered in many different types of reactors. In this paper, a particle-resolved algorithm for thermally thick biomass particle ... -
Influence of drag force correlations on periodic fluidization behavior in Eulerian-Lagrangian simulation of a bubbling fluidized bed
Ku, Xiaoke; Li, Tian; Løvås, Terese (Journal article; Peer reviewed, 2013)In this paper, an Eulerian–Lagrangian approach, in which the gas flow is solved by the volume-averaged Navier–Stokes equation and the motion of individual particles is obtained by directly solving Newton's second law of ...
