A 2D sediment bed morphodynamics model for turbulent, non-Newtonian, particle-loaded flows
(Chapter, 2017)In petroleum drilling, cuttings transport problems, i.e. an accumulation of drilled of solids in the wellbore, are a major contributor to well downtime and have therefore been extensively researched over the years, both ... -
A MULTI-DOMAIN 1D PARTICLE-REACTOR MODEL FOR PACKED BED REACTOR REACTOR APPLICATIONS
(Chapter, 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 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. ... -

(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 ... -
Aluminium Filtration by Bonded Particle Filters
(The Minerals, Metals & Materials Series;2367-1181, Chapter, 2019)Non-metallic inclusions such as oxides, borides and carbides in aluminium melts are a major cause of product failure during both processing and use. To remove these inclusions, molten aluminium is usually filtered through ... -
Artificial Intelligence for Well Integrity Monitoring Based on EM Data
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Monitoring of integrity of plugged and abandoned (P&A'ed) wells is of interest for the oil and gas industry and for CO2 storage. The purpose of this study is to develop artificial intelligence (AI)-based approaches to ... -
Beryllium Reduction Potential in AlMg Cast Alloys
(The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)Beryllium is used in many aluminium-magnesium alloys to minimize molten metal oxidation and oxide entrainment. As beryllium containing dust and fumes have detrimental effects on health, its use has to be limited. The ... -
Calibration of Pipeline Steel Model for Computational Running Ductile Fracture Assessment
(ISOPE - International Offshore and Polar Engineering Conference. Proceedings;29, Chapter; Peer reviewed, 2019)A novel fracture calibration method is presented for material models applied in finite element analysis of pipeline steels exposed to running ductile fracture. The calibration is based on the drop-weight tear test which ... -
A cartesian cut-cell method, based on formal volume averaging of mass, momentum equations
(SINTEF proceedings;2387-4295, Chapter; Peer reviewed, 2017)Simulation of multiphase flows are generally treated by various classes of Eulerian methods, Lagrangian methods and various combinations of these. In the SIMCOFLOW initiative we have set out to develop a framework for ... -
CFD modeling of dynamic emulsion stability
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Assuring transport and separation of oil and water crude emulsions is of significant importance to the oil and gas industries. The crude oil, due to its profuse chemical composition, has complex dispersion and emulsion ... -
CFD SIMULATIONS OF AN ADDITIONAL H2 COMBUSTOR FOR IMPROVING EFFICIENCY IN CHEMICAL LOOPING COMBUSTION POWER PLANTS
(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 ... -
CFD simulations of the two-phase flow of different mixtures in a closed system flow wheel

A CFD STUDY ON THE IMPACT OF BARRIERS AND NONUNIFORMITIES ON FURNACE TAPPING
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Tapping of slag and metal from metal producing furnaces are often inconsistent and it is difficult to predict the outcome of the process. Nonuniformities in the particle bed has been hypothesized as reasons for inconsistent ... -
Charcoal and Use of Green Binder for Use in Carbon Anodes in the Aluminium Industry
(The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)Carbon anodes for aluminium production are produced from calcined petroleum coke (CPC), recycled anode butts and coal tar pitch (CTP). The CO2 produced during anode consumption contributes to a substantial amount of the ... -
Cleaning of polycyclic aromatic hydrocarbons (PAH) obtained from ferroalloys plant
(Chapter, 2017)Polycyclic Aromatic hydrocarbons (PAHs) are organic compounds consisting of only hydrogen and aromatic carbon rings. PAHs are neutral, non-polar molecules that are produced due to incomplete combustion of organic matter. ... -
