Wind Turbine Wake Interactions - The Influence of Shear on a Wind Turbine Wake
(Master thesis, 2015)Full wake measurements have been performed on a model wind turbine at NTNU s wind tunnel to investigate the impact of shear flow compared to uniform flow on the wake flow. Mean and turbulent velocity measurements have been ... -
Wind turbine wake meandering
(Master thesis, 2013)In this master thesis the meandering of the wake of a three bladed horizontal axis model wind turbine has been studied. Measurements have been conducted by the use of four hot-wire probes located at multiple nearby points ... -
Wind-driven Rain Exposure and Assessment of Building Integrated Photovoltaic Systems
(Master thesis, 2016)This thesis is written as the final semester project of the five-year Master of Science program of Civil and Environmental Engineering (Bygg- og Miljøteknikk) at the Norwegian University of Science and Technology (NTNU) ... -
Wind-driven upwelling of iron sustains dense blooms and food webs in the eastern Weddell Gyre
(Peer reviewed; Journal article, 2023)The Southern Ocean is a major sink of anthropogenic CO2 and an important foraging area for top trophic level consumers. However, iron limitation sets an upper limit to primary productivity. Here we report on a considerably ... -
Wind-induced Dynamic Response and Aeroelastic Stability of a Suspension Bridge crossing Sognefjorden
(Master thesis, 2012)This thesis is a feasibility study, with regards to aerodynamic stability, about the possibility of constructing a suspension bridge with a main span of 3700m over the Sogne Fjord in Norway. The design wind velocity for ... -

Wind-induced Dynamic Response of High Rise Buildings
(Master thesis, 2013)This thesis aims to investigate the dynamic response of a high rise concrete structure. Calculations are performed for Lerkendal Hotel, a slender 75 meter high building located in Trondheim. Buffeting response has been the ... -
Wind-Induced Response of Long-Span Suspension Bridges Subjected to Span-Wise Non-Uniform Winds: A Case Study
(Master thesis, 2017)The Hardanger Bridge has a main span of 1 310 meters which makes it the longest suspension bridge in Norway and among the top 15 longest in the world as of 2017. The bridge consists of only two traffic lanes and one ... -
Wind-wave directional effects on fatigue of bottom-fixed offshore wind turbine
(Journal article; Peer reviewed, 2019)The current trend for offshore wind energy is that larger turbines are placed on monopile foundations at increasing water depth. This requires larger foundations, increasing the importance of hydrodynamic loading. It is ... -
Wind-wave misalignment effects on floating wind turbines: motions and tower load effects
(Journal article; Peer reviewed, 2014)The dynamic responses of a spar, tension leg platform (TLP), and two semisubmersible floating wind turbines (FWTs) in selected misaligned wind and wave conditions are investigated using numerical simulation with an ... -
WindBarge - Initial Design and Preliminary Assessment of Fatigue Damage
(Master thesis, 2017)Offshore wind is an increasing sector within renewable energy, and WindBarge aims to fill a gap in the offshore development, with a simple and cost efficient design targeted towards intermediate water depths between 40-60 ... -
Winding and Testing of Superconducting Coils
(Master thesis, 2015)Superconducting rotor windings are considered for future large offshore wind turbines for their low weight, volume and their possibility to reduce costs. In a joint European project, INNWIND.EU, a superconducting small ... -
Windjammer: Finding Purpose and Meaning on a Tall Ship Adventure
(Peer reviewed; Journal article, 2023)The Windjammer project started in 2018 as a social entrepreneurship program in Norway for adolescents at risk of social drop-out and societal exclusion. While the effects on society of such programs are difficult to measure, ... -
Window design optimization in terms of daylight and thermal comfort for a typical Norwegian residential building
(Master thesis, 2021)Vindusdesign påvirker dagslystilgjengeligheten, termisk komfort i tillegg til energibehovet til bygningen. Et uheldig vindusdesign kan medføre at et bygg går fra god til dårlig ytelse. I denne masteroppgaven er norske ... -
Window Size Effects on Subjective Impressions of Daylit Spaces: Indoor Studies at High Latitudes Using Virtual Reality
(Peer reviewed; Journal article, 2020)Daylight provision to the indoor space is affected by different building elements that cannot be fully controlled by the users, such as the window size of a space. The dimensions of the fenestration not only affect the ... -
Window spacers and edge seals in insulating glass units: A state-of-the-art review and future perspectives
(Journal article; Peer reviewed, 2013)Insulating glass (IG) units typically consist of multiple glass panes that are sealed and held together structurally along their perimeters. This report describes a study of edge seals in IG units. First, we summarize the ... -
Window view of nature after brief exercise improves choice reaction time and heart rate restoration
(Peer reviewed; Journal article, 2020)Research indicates that natural environments induce restorative effects on cognitive capacity and autonomic arousal. The present study investigates differences in choice reaction time (CRT) and heart rate responses in ... -
