(Master thesis, 2022)Den maritime sektoren møter strengere krav i forbindelse med klimagassutslipp basert på fremtidsplaner om nullutslippshavner langs Norges kyst innen 2026 og restriksjoner pålagt av Den internasjonale sjøfartsorganisasjonen ... -
Thermal energy storage for environmental energy supply
(Master thesis, 2012)The increasing energy consumption in the building sector enforces development in the field. One aims to cut the link between energy production and consumption, in order for environmental energy supply more of the demand ... -
Thermal Energy Storage with PCM for Refrigerated Sea Water System of Fishing Vessels
(Peer reviewed; Journal article, 2021)This paper investigates thermal storage integration with the refrigerated seawater (RSW) system of a fishing vessel. Four different scenarios were investigated, including ice in tanks, two design modifications in chilling ... -
Thermal Equilibrium and Wet Gas Compressor Performance
(Master thesis, 2011)The wet gas performance model established for this master s thesis is based on results achieved from a single stage, low pressure ratio, centrifugal compressor set up at NTNU. Water droplets are injected to the flow right ... -
Thermal evolution of the crystal structure and phase transitions of KNbO3
(Journal article; Peer reviewed, 2018)The thermal evolution of the crystal structure and phase transitions of KNbO3 were investigated by high-temperature powder X-ray diffraction and Rietveld refinement of the diffraction data. Two phase transitions from ... -
Thermal evolution of the crystal structure of proton conducting BaCe0.8Y0.2O3-δ from high-resolution neutron diffraction in dry and humid atmosphere
(Peer reviewed; Journal article, 2015)The crystal structure of the proton conducting perovskite BaCe0.8Y0.2O3−δ (BCY20) has been studied via high-resolution in situ neutron diffraction performed in controlled dry and humid (heavy water) oxygen flow. Two phase ... -
Thermal expansion and electrical conductivity of Fe and Cu doped MnCo2O4 spinel
(Journal article; Peer reviewed, 2018)Manganese cobalt spinel oxides are promising coating materials for corrosion protection of metallic interconnects in solid oxide fuel cell stacks. This work investigates how Fe and Cu doping affect the crystal structure, ... -
Thermal expansion of SrxBa1−xNb2O6 across and above the ferroelectric phase transition
(Peer reviewed; Journal article, 2024)Lead-free SrxBa1−xNb2O6(SBN) is of interest due to flexible chemistry, ferroelectric behavior, and electro-optic properties. The thermal expansion coefficient for SBN is reported only for compositions x = 0.35–0.59 and ... -
Thermal Fatigue in High Current Density Induction Coils

Thermal fatigue in stationary aluminium contacts
(Doktoravhandlinger ved NTNU, 1503-8181; 2001:113, Doctoral thesis, 2002)The conductive area of a stationary electrical contact consists of many small contact spots. The contact spots can be described as narrow metal bridges across the interface between two conductors. Deterioration of a contact ... -
Thermal flow in fractured porous media and operator splitting
(Master thesis, 2014)Thermal flow in fractured porous medium is an area of interest for both the oil and the geothermal energy industry. The mathematical model consists of multiple equations, often various conservation laws and constitutive ... -
Thermal fluctuations and vortex lattice structures in chiral p-wave superconductors: Robustness of double-quanta vortices
(Peer reviewed; Journal article, 2021)We use large-scale Monte-Carlo simulations to study thermal fluctuations in chiral p-wave superconductors in an applied magnetic field in three dimensions. We consider the thermal stability of previously predicted unusual ... -
Thermal Forge Welding Simulations: A Weldability Study of X65 Pipeline Quality
(Master thesis, 2011)Shield active gas forge welding is a time-efficient welding technique for solid statewelding of pipelines. Pipes are first heated by induction or ohmic resistance, and areforged together using an active shielding gas to ... -
Thermal gradient driven domain wall dynamics
(Journal article; Peer reviewed, 2019)The issue of whether a thermal gradient acts like a magnetic field or an electric current in the domain wall (DW) dynamics is investigated. Broadly speaking, magnetization control knobs can be classified as energy-driving ... -
Thermal Gradients and Thermal Conductivity in PEM Fuel Cells, Compared to Li-Ion Batteries and Super Capacitors
(Journal article; Peer reviewed, 2018)The PEMFC has been developed into a very effective energy converter. That is, the PEMFC offers high power at the same energy efficiency range. This is because the cell potential remains constant while current density ... -
