The Effect of Hydrogen Enrichment on the Thermoacoustic Behaviour of Lean Premixed Flames
(Doctoral theses at NTNU;2022:23, Doctoral thesis, 2022)Gas turbines (GT) burning hydrogen can help deliver large-scale zero carbon power generation and facilitate rapid decarbonisation over the short to medium term. They can also play a crucial role in increasing the penetration ... -
Rock physics model of shale: Predictive aspect
(Peer reviewed; Journal article, 2021)Shales often show strong elastic anisotropy that originate from the alignment and platy nature of its constituent minerals. Despite its impact on AVO (Amplitude Variation with Offset) response and seismic time-shifts, ... -
Towards understanding the interconnection between celestial pole motion and earth’s magnetic field using space geodetic techniques
(Peer reviewed; Journal article, 2021)The understanding of forced temporal variations in celestial pole motion (CPM) could bring us significantly closer to meeting the accuracy goals pursued by the Global Geodetic Observing System (GGOS) of the International ... -
Rapid change of particle velocity due to volatile gas release during biomass devolatilization
(Peer reviewed; Journal article, 2021)Our earlier study showed significant differences in average particle velocity between simulation and experimental results for devolatilizing biomass particles in an idealised entrained flow reactor [N. Guo et al., Fuel, ... -
Product formation during discharge: a combined modelling and experimental study for Li–O2 cathodes in LiTFSI/DMSO and LiTFSI/TEGDME electrolytes
(Peer reviewed; Journal article, 2021)Li–air or Li–O2 batteries are a promising energy storage technology due to the potentially high energy density. However, significant challenges related to reversible charge/discharge of these cells need to be solved. The ... -

Earthquake Response Analysis of Buildings
(Master thesis, 2021)Denne masteroppgaven studerer jordskjelvanalyse ved å bruke forenklet metode i henhold til Eurokode 8. Tre forskjellige modeller blir studert, modell 1 hvor jordtrykk er langs en av de langsgående kjellerveggene og hvor ... -
Full Waveform Inversion of Wide-Angle Ocean Bottom Seismometer data of a synthetic subduction zone model
(Master thesis, 2021)The water, which penetrated the upper part of the crust gets dragged down in a subduction zone, consecutively it gets released due to increasing heat and migrates in the above tectonic plate. This is believed to be the ... -
Free-Space Optical Communication: From Space to Ground and Ocean
(Peer reviewed; Journal article, 2021)During the last decade, there has been a rapid advancement in the area of mobile broadband and wireless communication. The demand for higher data rate and capacity has continuously increased thanks to the growing need for ... -
Communication Technologies for Smart Grid: A Comprehensive Survey
(Peer reviewed; Journal article, 2021)With the ongoing trends in the energy sector such as vehicular electrification and renewable energy, the Smart Grid (SG) is clearly playing a more and more important role in the electric power system industry. One essential ... -
Space heating solution using solar heat from a PVT system
(Master thesis, 2021)Målet med masteroppgaven er å utvikle et romoppvarmingssystem med bruk av varme fra et solcelle/solfanger (PVT) system. Basert på dette ble tre forskningsspørsmål definert. The første spørsmålet er å beskrive og vurdere ... -
Managerial work and behaviour pattern - within a cluster of small to medium oil service companies.
(Master thesis, 2021)Vi har i denne oppgaven sett nærmere på en leders tidsbruk, arbeidsaktiviteter og verbal kommunikasjon i en klynge på ca 40 olje service bedrifter på vestkysten av Norge. Dataene ble samlet inn ved hjelp av en kombinasjon ... -
Syklisters hastighet på vinterføre
(Master thesis, 2021)Med et økende søkelys på klima og klimagassutslipp, er det et ønske å få flere til å bruke sykkel som transportmiddel. Transportsektoren har de siste årene sett en økning i bruk av sykkel i de store byene. Likevel faller ... -
Computationally efficient coarse-graining XDEM/CFD modeling of fixed-bed combustion of biomass
(Peer reviewed; Journal article, 2022)In the multi-scale modeling of a dense particle system, the particle phase and the gas phase can be modeled on vastly different scales. The coupling between the two models has a critical influence on the predictions obtained ... -
CFD modeling of biomass combustion and gasification in fluidized bed reactors using a distribution kernel method
(Peer reviewed; Journal article, 2022)A three-dimensional reactive multi-phase particle-in-cell (MP-PIC) model is employed to investigate biomass combustion and gasification in fluidized bed furnaces. The MP-PIC model considered here is based on a coarse grain ... -
Built-in moisture in cross-laminated timber roofs – a field study
(Peer reviewed; Journal article, 2021)Cross-Laminated Timber (CLT) elements have had a growing popularity in recent years due to i.e. low carbon footprint, low weight and efficient construction time. However, the elements are sensitive to moisture and prone ... -
Inspection-based Preventive Maintenance Model with a Semi Markov Process - An Application to Aviation Fueling Facilities
(Master thesis, 2021)There is a long-standing interest in the study of condition-based maintenance (CBM) integrated with continuous monitoring schemes accompanied by enormous initial investments. The cost for continuous monitoring might be ... -
SiC-YAG coating microstructure optimization trough powder feedstock manufacturing process control
(Master thesis, 2021)ThermaSiC is a SiC/YAG composite powder feedstock material used to produce SiC based thermal spray coatings. Produced by the agglomerated and sintered route (A&S), it possesses a typical A&S morphology (spherical, relatively ... -
