Local entropy generation and entropy fluxes of a transient flame during head-on quenching towards solid and hydrogen-permeable porous walls
(Peer reviewed; Journal article, 2021)Premixed H2-air flames are studied in a one-dimensional wall-bounded configuration. The laminar flame propagates towards and quenches at a wall that is either solid or permeable. Entropy generation by each of 19 elementary ... -
Local Heating Networks with Waste Heat Utilization: Low or Medium Temperature Supply?
(Peer reviewed; Journal article, 2020)District heating enables an economical use of energy sources that would otherwise be wasted to cover the heating demands of buildings in urban areas. For efficient utilization of local waste heat and renewable heat sources, ... -
Low Aerodynamic Drag Suit for Cycling - Design and Testing
(Master thesis, 2015)The focus on garment aerodynamics is increasing in high velocity sports where aerodynamics are crucial such as cycling, speed skating and alpine skiing. Recently published research show that a low drag suit manipulating ... -
Low Temperature Applications for CO2 Capture in Hydrogen Production
(Chapter, 2020)The recent development of the protonic membrane reformer (PMR) technology allows an energy efficient hydrogen production from natural gas. To liquefy and separate CO2 from the retentate gas of the PMR, various low temperature ... -
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 ... -
