Wind Load Module For CSi ETABS
(Master thesis, 2015)For korrekt dimensjonering av konstruksjoner er det viktig å medberegne miljøbelastninger, inkludert vindlaster. I Norge bestemmes vindlaster ved bruk av NS-EN 1991-1-4:2005+NA:2009. Regelverket er utformet for håndberegninger, ... -
Wind load on feed barge
(Master thesis, 2022)Fish is a kind of sustainable food for healthy diet, and it plays an important role in fulfilling human's future needs for healthy food. Norway is the world's largest fish exporter, and nearly half of the Norwegian fish ... -
Wind power - An assault on local landscapes or an opportunity for modernization?
(Journal article; Peer reviewed, 2012)Wind power development has produced controversies in many places. Some people see wind power as a sustainable source of energy, others see it as destroying nature and landscapes. The opposition to wind power is often ... -
Wind power for cooking
(Master thesis, 2023)Tilgangen på elektrisitet i Tanzania har det siste tiåret vært av de raskest voksende i subsahariske Afrika, med en økende tilgang fra 7% til 37.7% mellom 2011 og 2020. Selv om tilgangen i urbane områder har nådd 73.2%, ... -

Wind Power Investment under Uncertainty and Simultaneous Electricity and Green Certificate Equilibrium
(Master thesis, 2014)This paper introduces the combination of an equilibrium model for electricity- and certificate supply and demand of and real options valuation theory for evaluating the effectiveness of support schemes applied in the ... -
Wind Power on Frøya: From Controversy to Decision-Making
(Master thesis, 2022)Denne masteroppgaven undersøker vindkraftkontroversen og -beslutningstakingen på Frøya i Trøndelag i Midt-Norge. Vindkraft har blitt en kontroversiell energi kilde. Fra å bli oppfattet som et positivt bidrag i kampen mot ... -
Wind power plant grid-forming control and influences on the power train and power system oscillation
(Chapter, 2022)In future power systems, wind power plants are supposed to contribute in the voltage and frequency stability of the grid. For this purpose, the control strategy of the wind power-frequency converter system needs to change ... -
Wind Powered Marine Vehicle - A Concept Study
(Master thesis, 2015)In conventional sailboat design, the heeling momentum introduced by the rigid connection of foils in air and water is a limitation on the maximum ve- locity. By removing the hull all together, wetted surface induced drag ... -
Wind Powered Water Injection Systems for Oil and Gas Applications
(Master thesis, 2016)The project is focused on the modelling and control of water injection systems (WIS) in oil and gas (O&G) facilities powered by wind turbines. The use of wind power for WIS has been presented by DNV-GL as an sustainable, ... -
Wind pressure coefficients for roof ventilation purposes
(Journal article; Peer reviewed, 2018)Wind pressure coefficients (cp) are important inputs for analytical calculations of wind load. The aim of this research is to investigate wind pressure coefficients on a test house located in Norway in order to pave the ... -
Wind tunnel experiments on wind turbine wakes in yaw: effects of inflow turbulence and shear
(Journal article; Peer reviewed, 2018)The wake characteristics behind a yawed model wind turbine exposed to different customized inflow conditions are investigated. Laser Doppler anemometry is used to measure the wake flow in two planes at x∕D = 3 and x∕D = 6, ... -
Wind tunnel experiments on wind turbine wakes in yaw: redefining the wake width
(Journal article; Peer reviewed, 2018)This paper presents an investigation of wakes behind model wind turbines, including cases of yaw misalignment. Two different turbines were used and their wakes are compared, isolating effects of boundary conditions and ... -
Wind tunnel investigation on the effect on the turbine tower on wind turbines wake symmetry
(Journal article; Peer reviewed, 2017)In wind farms, the wake of the upstream turbines becomes the inflow for the downstream machines. Ideally, the turbine wake is a stable vortex system. In reality, because of factors like background turbulence, mean flow ... -
Wind tunnel model testing of offshore platforms
(Master thesis, 2012)The purpose of this thesis is to highlight some of the areas of interest when it comes to wind tunnel experimenting of offshore platforms regarding stability concerns such as critical angles and wind overturning moment. ... -
Wind tunnel study on power output and yaw moments for two yaw-controlled model wind turbines
(Journal article; Peer reviewed, 2018)In this experimental wind tunnel study the effects of intentional yaw misalignment on the power production and loads of a downstream turbine are investigated for full and partial wake overlap. Power, thrust force and yaw ... -
Wind Tunnel Study on the Tip Speed Ratio’s Impact on a Wind Turbine Wake Development
(Peer reviewed; Journal article, 2022)(based on the turbine diameter and the freestream velocity). For all cases, the mean streamwise velocity deficit at the centerline evolves close to a power law in the far wake, and we check the validity of the Jensen and ... -
Wind Tunnel Testing of Bridge Decks
(Master thesis, 2016)The studies done in this thesis was connected to an early stage implementation of a new test method for ?nding aerodynamic properties of bridge deck sections at the Norwegian University of Science and Technology (NTNU), ... -
