Validation of Soot Modelling in the CFD code FLACS
(Master thesis, 2019-06-19)In a fire scenario, the role of soot is important from different standpoints. It has a significant contribution to heat transfer by radiation and it proves to be a hindrance in evacuation activities as it reduces visibility. ... -
Vannbasert eor i oppsprukne bergarter - økt oljeutvinning ved kjemikalietilsetning i injeksjonsvannet
(Master thesis, 2010-06-01)En stor del av verdens hydrokarbonreserver finnes i karbonater. Karbonatreservoarer er komplekse fordi reservoarbergarten ofte er sprø og sprekker lett. Mineralsammensetningen av karbonater gjør poreoverflaten mer tilbøyelig ... -
Vanninjektivitet og svekking av kalk under injeksjon av kaldt vann
(Master thesis, 2014-12-05)Primær oljeutvinning ved trykkavlastning gir ofte lav utvinningsgrad, og etterlater stor restoljemetning i reservoaret. For å forbedre oljeutvinningsgraden kan andre produksjonsmetoder benyttes; vanninjeksjon har i lang ... -
Vannutfelling på rustoverflater i gassrør
(Master thesis, 2009-06-12)Målet for denne oppgaven har vært å legge et grunnlag for beregninger av vannegenskaper i adsorbert fase på rust. Egenskaper bestemmes av et antall kompliserte termodynamiske og kinetiske mekanismer, som gjør at problemstillingen ... -
Variation in relative biological effectiveness for cognitive structures in proton therapy of pediatric brain tumors
(Journal article; Peer reviewed, 2021)Background Clinically, a constant value of 1.1 is used for the relative biological effectiveness (RBE) of protons, whereas in vitro the RBE has been shown to vary depending on physical dose, tissue type, and linear energy ... -
Variation of bending rigidity with material density: bilayer silica with nanoscale holes
(Journal article; Peer reviewed, 2022)Two dimensional (2D) materials are a young class of materials that is foreseen to play an important role as building blocks in a range of applications, e.g. flexible electronics. For such applications, mechanical properties ... -
Vector meson photoproduction in UPCs with FoCal
(Journal article; Peer reviewed, 2023)We discuss the physics prospects of photon-induced measurements using the high-granularity FoCal detector to be installed at the ALICE experiment, covering the pseudorapidity interval 3.4 ≤ η ≤ 5.8. This new detector, ... -
Veksling mellom ulike fokus i et utvalg av læreres veiledning av elever under praktisk natufagsarbeid
(Master thesis, 2015-06-08)Dialogue and discourse in science classrooms have been well studied, and multiple articles have been written about both challenges and opportunities related to classroom dialogue between teacher and students. In my master's ... -
Velocity distributions in microskimmer supersonic expansion helium beams: High precision measurements and modeling
(Peer reviewed; Journal article, 2018)Supersonic molecular beams are used in many applications ranging from spectroscopy and matter wave optics to surface science. The experimental setup typically includes a conically shaped, collimating aperture, the skimmer. ... -
Vented gas and dust explosions - External explosions
(Master thesis, 2016-06-01)The use of explosion venting is a widely applied safety measure, mitigating the effects of an internal gas and dust explosion. Implementation of this safety measure does however not eliminate all risks and hazards associated ... -
Vented hydrogen deflagrations in weak enclosures: Experimental results and implications for industrial practice
(Peer reviewed; Journal article, 2019)It is common practice in industry to install equipment for hydrogen energy applications in containers and smaller enclosures. Fires and explosions represent a significant hazard for such installations (Skjold et al., 2018), ... -
Versatile compressive microscope for hyperspectral transmission and fluorescence lifetime imaging
(Journal article; Peer reviewed, 2022)Increasing demand for multimodal characterization and imaging of new materials entails the combination of various methods in a single microscopic setup. Hyperspectral imaging of transmission spectra or photoluminescence ... -
Videreutvikling av instrumentering - for studier av mikroalgers vertikalmigrasjon under ulike lysforhold
(Master thesis, 2017)Mikroalger er viktige som primærprodusent i økosystem, både som næring til andre organismer men også som oksygenprodusent. Endringer av miljøforhold som lysintensitet, bølgelengde og tilgang på næringsstoffer, vil påvirke ... -
Viking and early middle ages Northern Scandinavian textiles proven to be made with hemp
(Peer reviewed; Journal article, 2013-10-18)Nowadays most plant textiles used for clothing and household are made of cotton and viscose. Before the 19th century however, plant textiles were mainly made from locally available raw materials, in Scandinavia these were: ... -
Viscous potential flow analysis of peripheral heavy ion collisions
(Peer reviewed; Journal article, 2013-02-19)The conditions for the development of a Kelvin-Helmholtz instability (KHI) for the quark-gluon plasma (QGP) flow in a peripheral heavy ion collision is investigated. The projectile and target side particles are separated ... -
Visual analysis of hydrate growth and layering behaviour in hydrate bearing silica and quartz sediments
(Master thesis, 2020-08-05)Gas hydrates are crystalline solids with cage-like structures of water containing a guest molecule. They have sparked great interest due to their potential as an energy source, and the possibility of utilizing them for ... -
