Lift Control of Adaptive Wind Turbine Blades with Bend-Twist Coupling
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:215, Doctoral thesis, 2014)A major challenge in the development of wind turbines comes with designing the blades so that they are robust, low weight, cost effective and highly efficient. As the industry develops and as more turbines are built in ... -
Lifting sustainable food science from lab to industry: An experimental study and development of a Soluble Gas Stabilisation (SGS) flow concept using low-cost off-the-shelf components
(Master thesis, 2023)Bærekraftsspørsmål er viktige for designinteressenter. Mattrygghet er avgjørende for menneskers helse og en betydelig bidragsyter til klimaendringer. Matsvinn og emballasjebruk er problemer i dagens matindustri. En potensiell ... -
Line-focus solar concentration 10 times higher than the 2D thermodynamic limit
(Peer reviewed; Journal article, 2022)Line-focus solar concentrators have traditionally been limited by the 2D concentration limit due to the continuous translational symmetry in these systems. This limit is orders of magnitude lower than the 3D limit, severely ... -

Liquid Hydrogen Spills on Water—Risk and Consequences of Rapid Phase Transition
(Peer reviewed; Journal article, 2021)Liquid hydrogen (LH2 ) spills share many of the characteristics of liquefied natural gas (LNG) spills. LNG spills on water sometimes result in localized vapor explosions known as rapid phase transitions (RPTs), and are a ... -
Literature Review and Statistical Analysis of Assembly Line Characteristics in Assembly System Design
(Master thesis, 2020)Monteringslinjer er kostnadseffektive produksjonssystemer som setter sammen deler til ferdige produkter. På grunn av endring i kundemønster tvinges flere monteringslinjer til å tilpasse seg, fra masseproduksjon av ... -
Litjfossen Pumpekraftverk (KVO) - Utnytting av prisvariasjoner i Midt-Norge
(Master thesis, 2016)Det norske kraftmarkedet er i endring. Aktiv handel, større mengde uregulert kraftproduksjon og bedre tilknytning til andre Europeiske land fører til at volatiliteten i kraftprisene øker. Med dagens utvikling og store ... -
Load Deflection Characteristics of Guide Vane End Seals
(Master thesis, 2017)This Master Thesis consider the load deflection characteristics of end seals incorporated in guide vanes used in hydropower turbines. The force response of the end seals is critical in order to prevent leakage and thus ... -
Local bracer vibrations for Offshore Wind jackets
(Master thesis, 2013)During the course of this master project, the candidates have worked with FEA of local vibrations occurring in bracers on offshore windturbine jacket. These vibrations arise as a dynamic response from wind-, wave-, and ... -
Local mechanical properties and precipitation inhomogeneity in large-grained Al–Mg–Si alloy
(Peer reviewed; Journal article, 2022)Al–Mg–Si (6xxx series) alloys show excellent mechanical properties due to the precipitates formed during heat treatment. However, heat treatment of these alloys results in a soft precipitation free zone (PFZ) close to grain ... -
Local strain energy based fatigue assessment of cruciform welded joints: experimental data analysis and influence of hot-dip galvanization
(Journal article; Peer reviewed, 2018)Performing the fatigue assessment of a welded joint using the Notch Stress Intensity Factors [1] presents two major challenges. The first is the necessity of a precise reconstruction of the stress field around the notch ... -
Local strain energy density for the fatigue assessment of hot dip galvanized welded joints: Some recent outcomes
(Journal article; Peer reviewed, 2017)Since in literature only data about the effect of the hot-dip galvanizing coating on fatigue behavior of unnotched specimens are available, whereas very few for notched components and none for welded joints, the aim of ... -
