Field investigation of thermal comfort level of patients and surgical staff in operating rooms at St Olavs hospital
(Master thesis, 2019)I helsetjenester og sykehusmiljøer er det viktig å kunne forutsi termisk komfort som en parameter for inneluftkvalitet. Ustabile termiske forhold er kritiske i operasjonsrommet og kan redusere arbeidseffektiviteten og øke ... -
Field investigations of the indoor air quality regarding the potential health effects in energy efficient buildings during the heating season
(Master thesis, 2016)In the search for energy reduction in the building sector, the focus on energy efficient buildings is increasing. In addition, people spend up to 90% of their time indoors. Norwegian office buildings experience low levels ... -

Film boiling and rapid phase transition of liquefied natural gas
(Doctoral theses at NTNU;2019:70, Doctoral thesis, 2019)When liquefied natural gas (LNG) is spilled onto water there is a possibility that explosive rapid phase transition (RPT) events occur. According to experiments, these vapor explosions are highly unpredictable, with yields ... -
Finite-size-dependent dispersion potentials between atoms and ions dissolved in water
(Journal article; Peer reviewed, 2014)A non-expanded theory is used for dispersion potentials between atoms and ions dissolved in a medium. The first-order dispersion interaction between two atoms in an excited state must account for the fact that the two atoms ... -
Finite-temperature Casimir effect in Randall-Sundrum models
(Journal article; Peer reviewed, 2010)The finite-temperature Casimir effect for a scalar field in the bulk region of two Randall–Sundrum models, RSI and RSII, is studied. We calculate the Casimir energy and the Casimir force for two parallel plates with ... -
Fire spread in a large compartment with exposed cross-laminated timber and open ventilation conditions: #FRIC-01 – Exposed ceiling
(Peer reviewed; Journal article, 2023)Exposing cross-laminated timber (CLT) structures in buildings is increasingly popular in modern buildings. However, large timber surfaces, window facades, and different geometries can change the fire dynamics in a compartment. ... -
Fire spread in a large compartment with exposed cross-laminated timber and open ventilation conditions: #FRIC-02 - Exposed wall and ceiling
(Journal article; Peer reviewed, 2023)Cross-laminated timber (CLT) is becoming increasingly popular due to its many advantages. However, it has been shown that exposed CLT can have a significant effect on fire dynamics and spread rates. Further studies are ... -
A First Integration of Anthropogenic Underwater Noise Pollution Impacts on Marine Ecosystems in an LCA Framework - The case of cetaceans in the North Sea
(Master thesis, 2016)The world s oceans provide many ecosystem services that are of high importance to human well-being. A variety of human activities, however, poses threats on the quality of the marine ecosystems. Due to the dependence of ... -
Fjerning av karbondioksid og tyngre hydrokarboner fra naturgass
(Master thesis, 2012)Denne oppgaven har tatt for seg et prosessanlegg for fjerning av karbondioksid og tyngre hydrokarboner ved bruk av lavtemperatur destillasjon, kombinert med en Dividing Wall Column. Målet har vært å undersøke mulighetene ... -
Flame dynamics of azimuthal forced spinning and standing modes in an annular combustor
(Journal article; Peer reviewed, 2018)Azimuthal forcing has been applied to flames in a laboratory scale annular combustor in order to accurately control the azimuthal mode of excitation. A new forcing configuration permitted not only the pressure amplitude, ... -
Flame Retardant Effect of Nano Fillers on Polydimethylsiloxane Composites
(Journal article; Peer reviewed, 2018)Polydimethylsiloxane has exceptional fire retardancy characteristics, which make it a popular polymer in flame retardancy applications. Flame retardancy of polydimethylsiloxane with different nano fillers was studied. ... -
Flame transfer functions and dynamics of a closely confined premixed bluff body stabilized flame with swirl
(Journal article; Peer reviewed, 2021)The flame transfer function (FTF) and flame dynamics of a highly swirled, closely confined, premixed flame is studied over a wide range of equivalence ratios and bulk velocities at a fixed perturbation level at the dump ... -
A flashing flow model for the rapid depressurization of CO2 in a pipe accounting for bubble nucleation and growth
(Peer reviewed; Journal article, 2023)Flashing flow is encountered in many industrial systems involving nozzles, valves and decompression of vessels and pipes. In the context of CO2 capture and storage (CCS), the design of safe and efficient CO2 transportation ... -
Flaskehalshåndtering i kraftsystemet med fleksibilitet som virkemiddel
