Assessment of Noise Production from Airfoils for Wind Turbines
(Bachelor thesis, 2022)Vindenergi er en lovende måte å produsere fornybar energi på, og det blir bygget flere nye vindparker nå enn noen gang tidligere. Likevel blir vindparker møtt med lokal motstand mange steder, og et av motstandernes argumenter ... -
Assessment of Operation of Biogas Production Plants in regards to Yield Factor, Energy Efficiency and Environmental Benefit
(Master thesis, 2019)Ei kontinuerleg aukande energietterspurnad og eit auka fokus på miljøvenlege energikjelder krev stadig utvikling og bruk av alternative energikjelder. Avfallsproduksjon er ein naturleg konsekvens av ein moderne livsstil. ... -
Assessment of organic Rankine cycle part-Load performance as gas turbine bottoming cycle with variable area nozzle turbine technology
(Peer reviewed; Journal article, 2021)Power cycles on offshore oil and gas installations are expected to operate more at varied load conditions, especially when rapid growth in renewable energies puts them in a load-following operation. Part-load efficiency ... -
Assessment of pressure swing adsorption as CO2 capture technology in coal-fired power plants
(Doctoral thesis at NTNU;2016:150, Doctoral thesis, 2016)Coal-based power generation is responsible for a significant share of CO2 emissions on a global scale. Technologies to drastically reduce coal carbon footprint are critical for meeting mitigation targets. Absorption, ... -
Assessment of the beneficial combination of electrochemical and ultrasonic activation of compounds originating from biomass
(Journal article; Peer reviewed, 2020)The electro-oxidation of organic molecules at the anode with simultaneous generation of hydrogen at the cathode in electrosynthesis reactors is considered as a promising and efficient process for the co-production of ... -
Assessment of the indoor environment of existing Norwegian dwellings
(Master thesis, 2020)Hensikten med dette arbeidet har vært å undersøke om et tilfredsstillende inneklima kan oppnås i soverom kun gjennom å åpne vinduet på natten. Det overordnede målet var å se om bruk av naturlig ventilasjon, i kombinasjon ... -
Assessment of the LES-FGM framework for capturing stable and unstable modes in a hydrogen / methane fuelled premixed combustor
(Peer reviewed; Journal article, 2023)The main objective of this paper is to assess the capability of compressible Large Eddy Simulations (LES) to capture azimuthal combustion instability. The thickened flame model coupled with Flamelet Generated Manifold (FGM) ... -
Assessment of the potential of small scale LPG technologies
(Master thesis, 2014)Many countries experience an economic growth, naturally leading to an increasing demand of energy. LPG is a relatively unknown energy carrier in Europe, whereas in other parts of the world LPG is used for daily cooking in ... -
Assessment of Transient NOx Reduction Potential in Wood Stoves
(Journal article; Peer reviewed, 2020)NOx emissions from wood stoves remain a significant concern, even though modern wood stoves are continuously improved regarding emissions due to incomplete combustion, e.g. particulates of organic origin. Today, state of ... -
Asynchronous and synchronous quenching of a globally unstable jet via axisymmetry breaking
(Peer reviewed; Journal article, 2022)We explore experimentally whether axisymmetry breaking can be exploited for the open-loop control of a prototypical hydrodynamic oscillator, namely a low-density inertial jet exhibiting global self-excited axisymmetric ... -
At what Pressure Shall CO2 Be Transported by Ship? An in-Depth Cost Comparison of 7 and 15 Barg Shipping
(Peer reviewed; Journal article, 2021)The pipeline has historically been the preferred means to transport CO2 due to its low cost for short distances and opportunities for economies of scale. However, interest in vessel-based transport of CO2 is growing. While ... -
Athermal glass work at the nanoscale: Engineered electron-beam-induced viscoplasticity for mechanical shaping of brittle amorphous silica
(Journal article; Peer reviewed, 2022)Amorphous silica deforms viscoplastically at elevated temperatures, which is common for brittle glasses. The key mechanism of viscoplastic deformation involves interatomic bond switching, which is thermally activated. Here, ... -
Attaining a higher flexibility degree in CO2 compressor racks
(Chapter, 2020)CO2 compressor racks have shown their suitability for commercial and industrial refrigeration systems at any location and climate. Even if some references state that CO2 units can compete in capital cost with any other ... -
Automated Prediction of Fractional Flow Reserve through Numerical Simulation of Coronary Artery Flow
(Master thesis, 2019)I denne masteroppgaven har det blitt utviklet en metode for å bestemme "Fractional Flow Reserve" indeksen for kvantifisering av funksjonell reduksjon i menneskelige kransarterier. Metoden har benyttet seg av den ... -
Automated Process Design in Oil and Gas Field Development
(Master thesis, 2018)Oil and Gas Processing plants require specialised equipment to effectively treat the hydrocarbons produced from the field. The processing equipment employed occupy a large amount of space and contribute a significant amount ... -
