A Lagrangian‐Eulerian hybrid model for the simulation of direct reduction of iron ore in fluidized beds
(SINTEF Proceedings;2, Chapter, 2017)Fluidized bed and moving bed reactors are one of the most important technologies in several branches of process industry. Especially, it is known since decades that iron can be reduced rapidly and efficiently from iron ... -
A multi-scale model for oxygen carrier selection and reactor design applied to packed bed chemical looping combustion
(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 multifluid‐PBE model for a slurry bubble column with bubble size dependent velocity, weight fractions and temperature
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)With kinetic gas theory as a starting point, equations of change for total mass, species mass, momentum and inner energy are developed for the dispersed gaseous phase and implemented to describe the Fischer-Tropsch synthesis ... -
A multi‐domain 1D particle‐reactor model for packed bed reactor applications
(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 ... -

A Norwegian ZEB-definition embodied emission
(ZEB Project report;17, Research report, 2014)This report deals with how to define what a Zero Emission Building (ZEB) is with explanation and analysis of different parameters related to embodied emissions of CO2 equivalents. The report can be used as a guidance tool ... -
A numerical approach to model aggregate restructuring in shear flow using DEM in Lattice‐Boltzmann simulations
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Aggregate shape and structure significantly impact rheological properties of fluids in many fields such as extractive metallurgy, oil field drilling and mineral processing. The morphology of the aggregates determines the ... -
A numerical evaluation of the effect of the electro‐magnetic force on bubble flow in aluminium smelting process
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)This paper aims to investigate the effect of electromagnetic forces on bubble flow under an anode using a computational fluid dynamics (CFD) model with the volume-of-fluid (VOF) method to capture the gas-liquid interface. ... -
