Wake Effect Mitigation of Floating Offshore Wind Farms Combining Layout Optimization, Turbine Repositioning and Yaw-based Wake Redirection
(Master thesis, 2023)Floating wind turbines despite the potential to harness energy from deep offshore areas where higher average wind speeds face challenges in terms of competitiveness. One approach to raising the competitiveness of a wind ... -
Wake flow and aerodynamic performance of time trial helmets
(Master thesis, 2019)Luftmotstand er den viktigste motstandskraften i sykkelkonkurranser. For å forbedre den aerodynamiske ytelsen blir det brukt tempohjelmer som er spesielt designet for å redusere luftmotstanden. Tempohjelmene som er ... -
Wake flow behind a curved cylinder
(Master thesis, 2014)This thesis reports the result of an experiment measuring the wake flow behind a curved circular cylinder at Re=3900 in water. The measurement technique used was Particle Image Velocimetry (PIV). The cylinder is a convex ... -
Wake Interactions and Performance Characteristics of a Pitched Model Wind Turbine
(Master thesis, 2015)In order to decrease the average costs of energy, wind turbines are arranged in wind farms where aerodynamic interactions between the turbines occur. When planning and optimizing the performance of a wind farm, these ... -
Wake Measurements Behind An Array Of Two Model Wind Turbines
(Master thesis, 2011)During the last decades the exploitation of energy from the wind has become one of the most promising renewable energy technologies. The main strive in today s development of wind turbines is to increase the efficiency of ... -
Wake Shielding Model Effect on Riser Dynamic Response
(Chapter, 2017)The paper provides a method to estimate the clearance between two flexible risers in tandem arrangement by taking into account the wake interference when subjected to a combined current plus waves flow. The wake interference ... -
Wake structures and vortex-induced forces of a controlled in-line vibrating circular cylinder
(Peer reviewed; Journal article, 2019)A two-dimensional numerical study was performed to investigate wake structures and fluid forces on a circular cylinder with prescribed vibrations in the in-line direction. Reynolds number was fixed at 500, and the SST k-w ... -
The walking speed of pedestrians on various pavement surface conditions during winter
(Peer reviewed; Journal article, 2021)This study aims to quantify the relationship between pedestrians’ walking speeds and various surface conditions typically associated with a winter environment. The purpose is to enable assessments of the effects of different ... -
Wall Modeled Large Eddy Simulation of Viscous Flow on the BeVERLI Hill Geometry
(Master thesis, 2021)I denne masteroppgaven har vegg-modellert LES blitt brukt til å simulere den viskøse strømningen over BeVERLI hill geometrien. BeVERLI hill er en veggmontert «bump» som blir brukt i valideringsstudier av turbulente separerte ... -
Wall thickness and scale effect on the quasi static compression and fatigue performance of AlSi10Mg sheet based lattices fabricated via selective laser melting
(Master thesis, 2022)AM-teknologi har åpnet muligheten for å produsere gitterstruktur metamaterialer som tidligere ikke var tilgjengelig gjennom standard produksjonsmetoder. I senere år har disse materialene sett et skifte fra kun å bli produsert ... -

Warmer and wetter winters: characteristics and implications of an extreme weather event in the High Arctic
(Journal article; Peer reviewed, 2014)One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells and heavy rain-on-snow (ROS) ... -
Warranty analysis of a two-component system with failure interaction
(Chapter, 2017)In recent decades, more and more attention has been paid to the warranty study of multicomponent systems. Compared to the reliability and cost analysis of single item systems, failure dependence between items is a major ... -
Warranty analysis of a two-component system with type I stochastic dependence
(Journal article; Peer reviewed, 2017)This article develops the warranty cost analysis of a two-component in-series system with stochastic dependence. From the perspectives of both the manufacturer and the consumer, the short-run total profits and costs under ... -
