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
(SINTEF Proceedings;1, Chapter, 2015) -
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 ... -
Characterisation of a Real-World Søderberg Electrode
(Peer reviewed; Journal article, 2021)Very little research on Søderberg electrodes has been published in the journal peer reviewed public domain. The main aim of this work is to characterise a Søderberg electrode that was cut off approximately 0.5 m below the ... -

(Peer reviewed; Journal article, 2021)Very little research on Søderberg electrodes has been published in the journal peer reviewed public domain. The main aim of this work is to characterise a Søderberg electrode that was cut off approximately 0.5 m below the ... -
Characterisation of structural similarities of precipitates in Mg–Zn and Al–Zn–Mg alloys systems
(Peer reviewed; Journal article, 2019)High angle annular dark field scanning transmission electron microscopy has been employed to observe precipitate structures in Al–Zn–Mg and Mg–Zn alloys. h1 precipitate structures in Al–Zn–Mg are commonly formed by MgZn2 ... -
Characteristic features of shale barrier materials
(Peer reviewed; Journal article, 2023)Deep wells in soft formations are completed with a steel tube (“casing”) that isolates the well from the surrounding rock. The annulus between the casing and the rock is usually left open in long sections of the well, thus ... -
Characterization and evaluation of synthetic Dawsonites as CO2 sorbents
(Journal article; Peer reviewed, 2019) -
Characterization and Modeling of CO2 Transport through Fluorinated Thermoplastics
(Peer reviewed; Journal article, 2023)Carbon capture and storage (CCS) is one of the most viable solutions to limit the CO2 emission in the atmosphere, with the potential to be applied at short-medium time scales. In this concern, polymeric materials play a ... -
Characterization of a Si-SiO2 mixture generated from SiO and CO
(Peer reviewed; Journal article, 2019)The reaction between SiO(g) and CO(g) is a relevant intermediate reaction in the silicon production process. One of the products generated from this gas mixture is called by its color, brown condensate. In this paper, ... -
Characterization of ash deposits from municipal solid Waste (MSW) incineration plants
(Peer reviewed; Journal article, 2017)In this work, chemical compositions and micro morphologies and structures of ash deposits from two municipal solid waste-to-energy (WtE) plants in Norway were analyzed and characterized. The ash deposits were sampled from ... -
Characterization of ash deposits from municipal solid Waste (MSW) incineration plants

Characterization of flow dynamics and reduced-order description of experimental two-phase pipe flow
(Peer reviewed; Journal article, 2018)Two-phase dispersed and slug flows in a pipe are investigated using proper orthogonal decomposition (POD). The data are acquired through tomographic reconstruction of X-ray measurements, where holdup, cross-sectional phase ... -
Characterization of hollow glass microspheres with potential for regional climate intervention to preserve snow and ice surfaces
(Peer reviewed; Journal article, 2023)Cold regions including the Arctic are warming fast, resulting in increased losses of snow and ice cover. A climate intervention approach, where hollow glass microspheres (HGMs) are applied on snow and ice surfaces such as ... -
Characterization of liquid products from slow pyrolysis of woody biomass
(Peer reviewed; Journal article, 2022)In the present work, birch and spruce woodchips were pyrolyzed in a fixed bed reactor under different pyrolysis conditions. The effects of pyrolysis temperature and atmosphere (i.e., with and without gas purging) on yield ... -
Characterization of Microbial Diversity in Decayed Wood from a Spanish Forest: An Environmental Source of Industrially Relevant Microorganisms
(Peer reviewed; Journal article, 2022)Rotting wood is inhabited by a large diversity of bacteria, fungi, and insects with complex environmental relationships. The aim of this work was to study the composition of the microbiota (bacteria and fungi) in decaying ... -
Characterization of Porous Structures of Cellulose Nanofibrils Loaded with Salicylic Acid
(Peer reviewed; Journal article, 2020)Bleached and unbleached pulp fibers were treated with 2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO) mediated oxidation to obtain cellulose nanofibrils (CNFs). The resulting bleached and unbleached CNFs were mixed with ... -
Characterization of Rough PTFE Surfaces by the Modified Wilhelmy Balance Technique
