Quantification of aeroacoustic noise sources from wind turbines
(Master thesis, 2022-06-01)One of the major environmental concerns regarding wind energy is an increase in noise levels, both in the atmosphere and the ocean. In this study, the generation and propagation of aeroacoustic noise from wind turbines ... -
Sensitivity analysis in key parameters related to wind power production
(Master thesis, 2021-06-01) -
SFY: A free-drifting wave buoy for measuring surf waves
(Master thesis, 2023-06-01)Breaking waves have been studied for over a century. Still, there is an insufficient understanding of wave breaking due to limited in situ data. The high variability and the energetic environment in the surf zone makes it ... -

The Effect of Near-Well Heterogeneity on Spatial Distribution of Salt Precipitation During CO2 Injection
(Master thesis, 2024-06-03)The world is in need of a shift to cleaner energy, and carbon storage is expected to be an important part of the transition. Geological carbon storage is a process in which captured carbon dioxide (CO2) is injected into ... -
The Effects of Diabatic Heating on the Paradigmatic LC1 and LC2 Baroclinic Lifecycles
(Master thesis, 2023-06-01)Extratropical cyclones play a crucial role in determining mid-latitude weather, where the atmosphere is on average inducive to baroclinic instability. Literature has identified two lifecycle behaviors, one that is predominantly ... -
The importance of wind turbulence and coherence to the loads on a wind turbine blade
(Master thesis, 2019-06-25)The wind simulation method proposed by Paul S. Veers from Sandia National Laboratories has been checked for the measured wind velocities at 40m and 80m height at FINO1 platform. The Sandia method applied as it is, gives ... -
Tidal forcing and internal tide energetics around Svalbard: a numerical study
(Master thesis, 2020-06-27)The hydrostatic and linear Regional Ocean Modeling System (ROMS) is used to examine the tidal forcing and the resulting baroclinic response and energetics of internal tides generated around Svalbard in the Arctic Ocean. ... -
Transientstabilitet-implementering ved BESS for offshore mikronett i øymodus
(Master thesis, 2022-06-01)Konvensjonelle mikronett har tradisjonelt sikret spenning- og frekvensstabilitet med spinning-reserve fra roterende maskiner ved forstyrrelser i nettet. En økende andel av ikke-roterende energiproduksjon påvirker kraftsystemers ... -
Trends and internal variability in Brazilian hydropower catchments
