Novel theoretical tools in jet quenching
(Doctoral thesis, 2023-06-13)Jet quenching er studiet av hvordan egenskapene til en QCD-jet endrer seg når den passerer gjennom varmt nukleært materiale. Dette er relevant for kollisjoner av tunge ioner ved LHC og RHIC, da slike kollisjoner produserer ... -

Nuclear modification factor for charged pions and protons at forward rapidity in central Au plus Au collisions at 200 GeV
(Peer reviewed; Journal article, 2007-07)We present spectra of charged pions and protons in 0–10% central Au + Au collisions at View the MathML sourcesNN=200 GeV at mid-rapidity (y=0y=0) and forward pseudorapidity (η=2.2η=2.2) measured with the BRAHMS experiment ... -
Nuclear modification factor of light neutral-meson spectra up to high transverse momentum in p–Pb collisions at √sNN = 8.16 TeV
(Journal article; Peer reviewed, 2022)Neutral pion (π0) and η meson production cross sections were measured up to unprecedentedly high transverse momenta (pT) in p–Pb collisions at √sNN = 8.16 TeV. The mesons were reconstructed via their two-photon decay channel ... -
The number of link and cluster states: the core of the 2D q state Potts model
(Peer reviewed; Journal article, 2005-11-30)Due to Fortuin and Kastelyin the q state Potts model has a representation as a sum over random graphs, generalizing the Potts model to arbitrary q is based on this representation. A key element of the random cluster ... -
A Numerical and Experimental Study of the Dispersion of a Dust Layer by a Rarefaction Wave
(Master thesis, 2017-06-22)In recent years, dynamics of dust lifting behind a passing shock wave have been studied extensively. Few studies have focused on the problem of dust lifting by a rarefaction wave. The aim of this study was to create a ... -
Numerical and experimental study of the vortex length in a gas cyclone
(Master thesis, 2012-09-01)Numerical and experimental study of the vortex length in a gas cyclone. Using a central composite design to find which factors influence the vortex length. -
Numerical computations of pressurized liquefied gas releases into the atmosphere
(Doctoral thesis, 2012-04-13)There is great concern about accidental releases and dispersion of toxic and flammable industrial chemicals into the atmosphere. Their toxic effects and/or flammable properties, combined with their widespread use and ... -
Numerical investigation of a transformable modular PET system: Consideration of point-spread functions, module arrangements, and operation protocols
(Journal article; Peer reviewed, 2019)Positron emission tomography (PET) is a powerful tool for mapping the dynamic distribution of substances in visually opaque systems. A modular, scalable, transformable, and relocatable PET system is custom built to provide ... -
Numerical investigation of direct absorption solar collectors based on carbon black nanofluids
(Journal article; Peer reviewed, 2023)A novel model of a rectangular direct absorption solar collector (DASC) based on carbon black (CB) nanofluids for concentrated solar power is presented herein. Distributions of temperature, velocity, volume fraction of ... -
Numerical Investigation of Natural Gas Hydrate Agglomeration and Deposition in High Water Cut Pipeline Systems
(Master thesis, 2018-06-20)The phenomena of gas hydrate plugging constitute a well known problem in the petroleum production and transport industries. Nevertheless, this issue is still not fully understood, especially for high water cut systems. For ... -
Numerical Investigation of Particle Dispersion in a Gravitational Field and in Zero Gravity.
(Master thesis, 2017-08-31)Combustible solid particles dispersed in gas has previously been discovered to be a precursor to a potential dust explosion. Consequently, a growing interest on the subject has been observed in recent years. Numerous ... -
Numerical Modeling of Supercritical ‘Out-Salting’ in the “Atlantis II Deep” (Red Sea) Hydrothermal System
(Peer reviewed; Journal article, 2007)Supercritical water behaves close to that of a non-polar fluid and its ability to dissolve salt ions is very low. In rifting locations world-wide, where hot vents occur, it has been shown that seawater attains supercritical ... -
Numerical simulations of the flow and plugging behaviour of hydrate particles
(Master thesis, 2010-05-06)Abstract The main hydrate mitigation used by the industry today is to avoid formation at all cost. Avoidance of hydrate formation is made possible by use of inhibitors such as methanol or glycol. These are so called ... -
A numerical study of ammonia dispersion in an industrial area with the CFD tool FLACS
(Master thesis, 2018-06-20)As the use of ammonia increases, knowledge about dispersion patterns and dispersion tendencies is of enhanced importance. Due to its toxic nature, very few realistic experiments of ammonia dispersion in complex situations ... -
A Numerical Study of Empty Nose Syndrome: an Evaluation of Nasal Aerodynamics
(Master thesis, 2018-06-20)Empty nose syndrome (ENS) is a rare complication of nasal surgery done to enlarge the internal nasal channels. The feeling of nasal obstruction despite patency is one of the most common symptoms among ENS patients. This ... -
A Numerical Study of Exercise Induced Laryngeal Obstruction using Fluid-Structure Interaction
(Master thesis, 2017-06-20)During inhalation, the pressure in the lungs decreases relative to the atmospheric air pressure, so that the atmospheric air is sucked into the lungs. During strenuous exercise, exposed individuals may experience that the ... -
A numerical study of flow field and particle deposition in nasal channels with deviant geometry
(Journal article; Peer reviewed, 2021)Deviant geometry of nasal channels results in significant changes to nasal aerodynamics that alter flow resistance, sensation, and the ability to filter aerosols. The invasive, operative modification of nasal geometry might ... -
