Wind Effects on a Sports Arena
(Master thesis, 2016)Wind effects on the Maier sports arena have been investigated with three different experiment types. The experiments were performed with open land and nearby structures , with south, southwest and west wind direction. ... -
Wind Farm Control Methods - Yawing
(Master thesis, 2016)The wake effect of yawing an upstream turbines is of interest in order to increase power production. In this study, the case of yawing is considered as asymmetric do to the tower and rotor rotation, and measurements have ... -
Wind farm performance
(Master thesis, 2016)Performance of the wind turbine in the wind farm has been analyzed using IEC61400-12-1 wind turbine power measurement standard. Ten minutes averaged wind data was acquired from Windcube v2 LIDAR over the period of twelve ... -
Wind farm performance - Power Analysis of a wind turbine
(Master thesis, 2016)Wind conditions from a wind farm situated in Ørland were analyzed based on a ten minute measurements in order to obtain the power and efficiency curves. The results from the analysis were compared with different curves ... -
Wind field measurements in urban environments
(Master thesis, 2021)Ettersom verden streber etter å senke klima utslipp og forurensing blir fokuset mer og mer rettet mot fornybar energiproduksjon. Kan vind produksjon i urbane miljøer bidra til å senke både lokale og globale utslipp. Et ... -
Wind Field Variability in Complex Terrain: Lessons from the Hardanger Bridge
(Chapter; Peer reviewed, 2019)Along the Coastal Highway E39 in the western coast of Norway, Norwegian Government is planning to build several extreme bridges spanning from 1.5 to 5 km. The region is typically mountainous with deep fjords seeping inland. ... -
Wind flow studies for drifting snow on roads /
(Dr. ingeniøravhandling, 0809-103X; 2002:82, Doctoral thesis, 2002)During strong winds, drifting snow causes problems on roads in many harsh winter climate countries. Increased snow-removal costs, reduced access and safety problems are typical results of excessive snowdrift sedimentation ... -
Wind forces on bridge decks using state-of-the-art FSI methods
(Doctoral theses at NTNU;2019:180, Doctoral thesis, 2019)Several bridges with span widths that challenge present technology are currently under planning in Norway, and wind effects are among the major concerns. Traditionally, wind-structure interactions are studied experimentally ... -
Wind in Complex Terrain - Lidar Measurements for Evaluation of CFD Simulations
(Journal article; Peer reviewed, 2018)Computational Fluid Dynamics (CFD) is widely used to predict wind conditions for wind energy production purposes. However, as wind power development expands into areas of even more complex terrain and challenging flow ... -
Wind Induced Dynamic Response of Concrete Box Girders During a Balanced Cantilevered Construction Stage
(Master thesis, 2013)In this thesis a theoretical study of wind induced dynamic response of line-like structures has been performed, followed up by calculations of the dynamic response of Dolmsundet Bridge in its critical construction stage. ... -
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
