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 ... -
