Droplet mobility and impacting dynamics on superhydrophobic surfaces
(Doctoral theses at NTNU;2024:347, Doctoral thesis, 2024)Droplet wetting phenomenon is crucial in various applications, such as antiicing and self-cleaning surfaces, heat transfer, water harvesting, and so on. The desired wettability can be achieved by a combination of physical ... -
The behaviour of NH3/H2/N2, CH4 and C2H8 turbulent premixed bluff-body stabilized flames near lean blow-off
(Journal article; Peer reviewed, 2024)The lean blow-off (LBO) behaviour of turbulent premixed bluff-body stabilized flames was investigated. Fuels with a range of Lewis numbers were used to examine differential diffusion characteristics, including NH3/H2/N2 ... -
Measurement of the Wood Stove Impact on the Electric Power Consumption of a Norwegian Detached House
(Journal article; Peer reviewed, 2023)Wood stoves are commonly used as space heating systems in Norwegian houses. However, the specific impact of wood stoves on electric power remains relatively unexplored and is investigated in our study. We also aim to reveal ... -
Optical Measurements and Numerical Modeling of the Temperature Distribution Across a Proton Exchange Membrane (PEM) Fuel Cell
(Master thesis, 2024)Effektiv varmestyring er avgjørende for å optimalisere ytelsen til Proton-utveksling membran (PEM) brenselsceller. Flere numeriske modeller er designet for å predikere temperaturvariasjonene til en PEM brenselcelle under ... -
Investigating Degradation and Lithium Plating Detection in Lithium-ion Batteries
(Master thesis, 2024)Litium-ionebatterier (LiB) er avgjørende i moderne energilagringsløsninger, og deres bemerkelsesverdige vekst forventes å øke i takt med det verdensomspennende grønne skiftet. Til tross for sine fordeler, har LiBs utfordringer ... -
Teaching Process Design – Quo Vadis?
(Journal article; Peer reviewed, 2024)The capstone course in chemical process design, together with its associated design project is the acid test to gauge the mastery of trainee chemical engineers. There is no other component in the chemical engineering ... -
Pressure Pulsations in Francis Turbines
(Master thesis, 2024)Med innføringen av intermitterende energikilder som sol og vind i energisystemet, og utfasingen av fossile brennstoff, vil Francisturbiner oppleve større lastendringer. Francisturbiner kan endre laster raskt for å balansere ... -
Quantifying Circular Economy Measures in Electrical and Electronic Equipment: An Environmental Model for Enhancing Sustainable Consumption and Reducing Carbon Footprint
(Master thesis, 2024)Denne masteroppgaven utforsker effekten av miljøtiltak rettet mot Sirkulær Økonomi (SØ) på karbonfotavtrykket forårsaket av elektrisk og elektronisk utstyr (EEU) og maskiner. Disse tiltakene har som mål å redusere avfall ... -
Assessing Emissions Savings: Renovation versus New Construction – A Case Study of a Public Building in Oslo
(Master thesis, 2024)Bygg- og anleggssektoren er ein viktig bidragsytar til den globale oppvarminga. Den er ansvarleg for ein stor del av ressursuttaket, noko som førar til betydeleg klimagassutslepp. Målet med denne studien er å vurdere og ... -
Numerical Investigation of Reheat Hydrogen Flames in the Sequential-Combustion Stage of a Heavy-Duty Gas Turbine
(Chapter, 2024)Recent theoretical studies and experimental evidence suggest that turbulent burning-rate augmentation, flame instabilities and NOx emissions, notoriously characterizing fuel-lean hydrogen premixed combustion, are significantly ... -
Assessing the undesired impacts on water sustainability from climate change mitigation technologies in fossil-based power generation
(Peer reviewed; Journal article, 2024)This work investigates the water impact of carbon capture technologies employed in coal and natural gas power generation, viz. the integrated gasification combined cycle, oxy-fuel combustion, solid oxide fuel cells and ... -
The Effect of Horizontal Shear on Extracting Water Currents From Surface Wave Data
(Journal article; Peer reviewed, 2024)The dispersive motion of surface waves is now routinely used to remotely measure the currents close beneath the surface of oceans and other natural flows. The current manifests as wavelength-dependent Doppler shifts in the ... -
