Simulating the Effect of Release of Pressure and Dust Lifting on Coal Dust Explosions
(Conference lecture, 2007)Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of a propagating flame can play an important role for explosion propagation in coal mines. In 1924, Greenwald and Wheeler investigated ... -
Simulating the Influence of Obstacles on Accelerating Dust and Gas Flames

Simulating vented hydrogen deflagrations: Improved modelling in the CFD tool FLACS-hydrogen
(Journal article; Peer reviewed, 2021)This paper describes validation of the computational fluid dynamics tool FLACS-Hydrogen. The validation study focuses on concentration and pressure data from vented deflagration experiments performed in 20-foot shipping ... -
Simulation and modelling of water spray in the 3D explosion simulation program FLACS
(Master thesis, 2004)In a gas processing plant and in offshore platforms a gas explosion could have serious consequences, and it is therefore essential to have mitigation systems that can prevent and/or reduce unwanted scenarios. One such ... -
Simulation of Enhanced Heavy Oil Recovery: History Match of Waterflooding and Polymer injection at Adverse Mobility Ratio
(Master thesis, 2015-06-01)Waterflooding and polymer flooding total recovery in the unstable immiscible displacement is very attractive and its applications are interesting in recent years. However, the simulation models of unstable immiscible ... -
Simulation of geomechanical effects of CO2 injection in cold aquifers with possibility of hydrate formation
(Chapter; Peer reviewed, 2011)The injection of CO2 in saline aquifers can have a significant impact on the geochemistry and the geo-mechanics of the reservoirs. Due to this injection, minerals will dissociate in regions with low pH or precipitate in ... -
Simulation of hydrate dynamics in reservoirs
(Chapter; Peer reviewed, 2011)Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon dioxide ... -
Simulation of Nanoparticle-Stabilized CO2-Foam in Sandstone
(Master thesis, 2019-09-24) -
Simulation of prompt gamma production in particle therapy and beam trajectory imaging
(Master thesis, 2015-06-01)In cancer oncology, using of Mega electron Volt (MeV) bremsstrahlung photons has been clinically practised on cancer patients since photons can deliver a significant dose to tumour volumes when projected into the body in ... -
Simulation of viscous instabilities in miscible and immiscible displacement
(Master thesis, 2008-06-09)This study includes modeling of viscous instabilities at both miscible and immiscible displacement. Oil recovery of heavy oil leads to unstable displacement for adverse mobility ratio for both miscible and immiscible ... -
Simulation Study of In-Situ Polymer Rheology in a Radial Flow Experiment
(Master thesis, 2018-06-27)The global energy demand is continuously growing, and even though renewable energy sources are becoming increasingly important, oil remains the leading energy fuel to this date, accounting for one third of the consumption. ... -
Simulation Study of Polymer Injectivity and Rheology in Radial Models
(Master thesis, 2017-08-02)The simulation study conducted in this thesis was carried out at the Centre for Integrated Petroleum Research (Uni CIPR) at the University of Bergen (UiB). The main objective in this thesis was to study polymer rheology ... -
Simulations of a Therapeutic Proton Beam with FLUKA Monte Carlo Code and Varian Eclipse Proton Planning Software
(Master thesis, 2013-11-20)The sharp dose deposition from protons in a medium has some clear advantageous aspects for use in cancer treatment. When charged particles, for instance protons, traverse matter, most of their energy are deposited at the ... -
Simulations of acoustic transmission loss of Fin whale calls reaching the LoVe Ocean Observatory
(Master thesis, 2018-12-18)Equinor has plans to develop a whale monitoring station using acoustic animal destiny estimation at their cabled ocean observatory, the LoVe Observatory, in Lofoten-Vesterålen basin. The fauna of this area is of remarkable ... -
Simulations of Busy Probabilities in the ALPIDE Chip and the Upgraded ALICE ITS Detector
(Peer reviewed; Journal article, 2018)For the Long Shutdown 2 (LS2) upgrade of the ITS detector in the ALICE experiment at the LHC, a novel pixel detector chip, the ALPIDE chip, has been developed. In the event of busy ALPIDE chips in the ITS detector, the ... -
Simulations of CO2 injection in saline aquifer formations
(Master thesis, 2009-07-14)This thesis is devoted to studies of long term storage of carbon dioxide in geological formations such as saline aquifers. The goal of the thesis is to contribute to the development of a totally integrated storage evaluation ... -
Simulering og analys av 3-fase strømningseksperimenter
(Master thesis, 2009-06-12)Formålet med denne oppgaven var å analysere og simulere strømningseksperimenter med 2 og 3 faser. Størsteparten av oppgaven dreide seg om å historietilpasse eksperimentene ved å endre relativ permeabilitetskurver og simulere ... -
Simultaneous Development of Multiple Auroral Substorms: Double Auroral Bulge Formation
(Journal article; Peer reviewed, 2021)The expansion phase of auroral substorms is characterized by the formation of an auroral bulge, and it is generally considered that a single bulge forms following each substorm onset. However, we find that occasionally two ... -
