Low temperature drying and thermo-physical Properties of Brown seaweeds (Saccharina latissima)
(Chapter, 2017)The drying kinetics of brown seaweed Sacharina Latissima with and without blanching were investigated in temperature range between 10.0 and 38.0 °C. The drying process is more rapid for raw seaweeds. The effective moisture ... -
Low Temperature Plate Freezing of Fish on boats using R744 as Refrigerant and Cold Thermal Energy Storage
(Master thesis, 2018)The introduction of low temperature R744 freezing systems enables lower evaporating temperatures and faster freezing times, however, also a lower system efficiency (COP). This thesis will investigate how low temperature ... -
Low-frequency oscillations in flow past an inclined prolate spheroid
(Journal article; Peer reviewed, 2019)We analyse the forces on a 45∘ inclined 6:1 prolate spheroid at Reynolds number ReD = 8000. In contrast to flow at lower Reynolds numbers previously investigated, we now find a strong oscillatory behaviour in the global ... -
Low-head pumped hydro storage: A review of applicable technologies for design, grid integration, control and modelling
(Peer reviewed; Journal article, 2022)To counteract a potential reduction in grid stability caused by a rapidly growing share of intermittent renewable energy sources within our electrical grids, large scale deployment of energy storage will become indispensable. ... -
Low-parameter linear model to activate the flexibility of the building thermal mass in energy system optimization
(Peer reviewed; Journal article, 2023)As buildings are becoming an integrated part of the energy system, the potential activation of the thermal mass as a source of flexibility needs to be considered in energy system modeling. Since energy system models represent ... -
Luftbåren oppvarming med konstante volumsystem (CAV) i passivhus
(Master thesis, 2020)Denne oppgaven undersøker luftbåren oppvarming med konstante volumsystem (CAV) i passivhus. Slike bygg kjennetegnes ved god isolasjonsevne og høy lufttetthet. Varmetilskudd fra sol og internlast kan derfor benyttes til å ... -
Luftmengders påvirkning på termisk komfort ved behovsstyrt ventilasjon
(Master thesis, 2014)For å imøtekomme nåværende og fremtidige krav til termisk komfort, luftkvalitet og energibruk i næringsbygg, er det nødvendig å anvende en ventilasjonsløsning som har til hensikt å redusere luftmengden til det aktuelle ... -
Luftsmitteisolat - Evaluering av dimensjoneringsgrunnlag og utførte løsninger
(Master thesis, 2008)De seneste år har det vært en økning i forekomsten av blant annet resistent tuberkulose og resistente stafylokokker. For å hindre smittespredning fra sykehusinnlagte pasienter med slike sykdommer til andre personer benyttes ... -
Lønnsomhet ved omfattende energioppgradering av et 60-tallshus
(Bachelor thesis, 2020)Denne rapporten inneholder en sammenligning av tre ulike energioppgraderinger for et 60-tallshus på Kolsås i Bærum. Hovedpoenget med oppgaven er å finne ut hvordan en omfattende energioppgradering av et 60-tallshus kan ... -
Løsninger for offshore flytende produksjonsinnretninger med minimal bemanning
(Master thesis, 2016)Flytende offshore-systemer brukes til produksjon og prosessering av olje og gass, spesielt i dype farvann. Redusert offshore-bemanning vil gi fordeler i form av økt sikkerhet og lavere operasjonelle utgifter, og kan ... -
