LDV Measurements in Centrifugal Pump Diffuser
(Master thesis, 2015)This thesis describes experimental research on the flow inside a vaned diffuser of a centrifugal pump. The measurements were conducted inside one of the ten curved diffuser channels on the single-stage centrifugal pump ... -
Leakage Vortex Progression through a Guide Vane’s Clearance Gap and the Resulting Pressure Fluctuation in a Francis Turbine
(Peer reviewed; Journal article, 2021)A clearance gap (CG) between guide vanes (GVs) and facing plates exists at both ends of a Francis turbine and allows the opening angle to be adjusted for varying operating conditions. Leakage flow is induced through this ... -
The legacy environmental footprints of manufactured capital
(Journal article, 2023)The foundations of today’s societies are provided by manufactured capital accumulation driven by investment decisions through time. Reconceiving how the manufactured assets are harnessed in the production–consumption system ... -
Lessons learned from an experimental campaign on promoting energy content of renewable biogas by injecting H2 during anaerobic digestion
(Peer reviewed; Journal article, 2020)Direct injection of H2 to an anaerobic reactor enables biological fixation of CO2 into CH4 (biomethanation) and consequently boosts methane content in the produced biogas. However, there has been only a small amount of ... -
Lettvektspotensialet for brenselceller i fly.
(Bachelor thesis, 2022)Luftfartssektoren opplever et skifte mot bærekraftig flyreise med en fokus på fremdriftssystemer drevet av fornybar energi. Brenselceller er et område som blir sett på for bruk i kommersielle fly. Solid Oxide brenselceller ... -
Leveraging opportunity of low carbon transition by super-emitter cities in China
(Peer reviewed; Journal article, 2023)Chinese cities are core in the national carbon mitigation and largely affect global decarbonisation initiatives, yet disparities between cities challenge country-wide progress. Low-carbon transition should preferably lead ... -
LiB Ageing Mechanisms and Energy Storage Replacement/Expansion in Marine Vessels
(Bachelor thesis, 2022)For å motverke klimaendringane, utvikle teknologi og senke kostnadar, så har ei rekkje elektriske ferjer vore sett i drift langs den norske kysten. Litium-ion batteri er teknologien som vert nytta til å lagre energi om ... -
LIB thermal regulation with PCM
(Bachelor thesis, 2023)Litium-ionbatterier (LIB) øker i etterspørsel og etter hvert som de blir tilpasset flere bruksområder må også kjøleteknologien tilpasses. Revolve NTNU er en studentorganisasjon som designer og konstruerer elektriske ... -
Lidars for Wind Tunnels - an IRPWind Joint Experiment Project
(Journal article; Peer reviewed, 2017)Measurement campaigns with continuous-wave Doppler Lidars (Light detection and ranging) developed at DTU Wind Energy in Denmark were performed in two very different wind tunnels. Firstly, a measurement campaign in a small ... -
Life cycle analysis of GHG emissions from the building retrofitting: The case of a Norwegian office building
(Peer reviewed; Journal article, 2021)Through a systematic study, this paper conducted a life cycle assessment (LCA) consisting of evaluation of both embodied and operational emissions of different building retrofitting scenarios for a typical office building, ... -
Life Cycle Analysis of remediation and utilization of bauxite residue: Evaluation of technologies from a location perspective.
(Master thesis, 2021)Bauxit rester eller redmud er gruvedriften rester (tailing) fra Bayer-prosessen med bauxittmalm, og med 4,6 milliarder tonn i reserver av farlige avfallsverdier er det nødvendig å inkludere det som restressurs i sirkulær ... -
Life cycle assessment demonstrates environmental co-benefits and trade-offs of low-carbon electricity supply options
(Journal article; Peer reviewed, 2017)The targeted transition towards an electricity system with low or even negative greenhouse gas emissions affords a chance to address other environmental concerns as well, but may potentially have to adjust to the limited ... -
Life Cycle Assessment of a Lithium-Ion Battery Vehicle Pack
(Journal article; Peer reviewed, 2014)Electric vehicles have no tailpipe emissions, but the production of their batteries leads to environmental burdens. In order to avoid problem-shifting, a life cycle perspective should be applied in the environmental ... -
