The inter-scale energy budget in a von Kármán mixing flow
(Peer reviewed; Journal article, 2020)A detailed assessment of the inter-scale energy budget of the turbulent flow in a von Kármán mixing tank has been performed based on two extensive experimental data sets. Measurements were performed at a Taylor microscale ... -
Interaction Between a Building Complex with an Integrated Thermal Energy System and a District Heating System
(Chapter, 2016)Integrated thermal energy systems provide heating and cooling for several commercial and residential buildings. These systems usually have both short-term and seasonal thermal energy storages. High cooling demands lead to ... -
Interaction between a simplified soft palate and compressible viscous flow
(Journal article, 2016)Fluid–structure interaction in a simplified 2D model of the upper airways is simulated to study flow-induced oscillation of the soft palate in the pharynx. The goal of our research has been a better understanding of the ... -
Interaction between trailing edge wake and vortex rings in a Francis turbine at runaway condition: Compressible large eddy simulation
(Journal article; Peer reviewed, 2018)The present study aims to investigate the unsteady flow phenomenon that produces high energy stochastic fluctuations in a highly skewed blade cascade. A complex structure such as a turbine is operated at runaway speed, ... -
Interaction between turbine pressure pulsations and transients in the penstock
(Master thesis, 2019)Utmattingsbrudd er et kjent problem i moderne høytrykks Francisturbiner. Når et løpehjul sprekker, medfører dette store kostnader for både eier av kraftverket og leverandøren av hjulet. Det er dokumentert flere tilfeller ... -
The interaction of droplet dynamics and turbulence cascade
(Peer reviewed; Journal article, 2023)The dynamics of droplet fragmentation in turbulence is described by the Kolmogorov-Hinze framework. Yet, a quantitative theory is lacking at higher concentrations when strong interactions between the phases and coalescence ... -
Interactive data visualization of the Norwegian phosphorus cycle, coupling phosphorus with dry matter and energy in a multi-layered material flow analysis model
(Master thesis, 2015)The utilization of data visualization to explore complex systems is arguably an indispensable method for increasing understanding of a specific problem domain. It is argued that visualization techniques for presenting ... -
Interface Tracking for 3D Immersed Boundary Method in Biofluid Dynamics
(Master thesis, 2022)Obstruktiv søvnapné er et medisinsk problem forårsaket av kollaps i de øvre luftveiene som begrenser oksygentilførselen under søvn, som fører til økt dødelighet og senket livskvalitet. For øyeblikket finnes det kirurgiske ... -
Interferon-γacutely augments inhibition of neocortical layer 5 pyramidal neurons
(Peer reviewed; Journal article, 2020)Background Interferon-γ (IFN-γ, a type II IFN) is present in the central nervous system (CNS) under various conditions. Evidence is emerging that, in addition to its immunological role, IFN-γ modulates neuronal morphology, ... -
Internal Leakage Impact on Compressor Performance
(Master thesis, 2015)Abstract With the discovery of Ekofisk in 1969 the Norwegian oil adventure started and up until today the work both offshore and onshore has given Norwegian industry a unique position in the world. Peak oil was reached in ... -
Internal Temperature measurements in Li-ion Pouch Cell using FBG
(Master thesis, 2021)I denne masteroppgaven har det blitt forsøkt å implementert FBG-sensorer i forhåndsproduserte lithium-ion batterier for intern temperaturmåling. Det ble brukt glasskapillærer for å isolere sensorene slik at de kun regaerte ... -
Internally circulating fluidized-bed reactor for syngas production using chemical looping reforming
(Peer reviewed; Journal article, 2018)Chemical looping reforming (CLR) is a promising method for achieving autothermal methane reforming without the energy penalty of an air separation unit that is required for partial oxidation (POX) or oxygen-blown autothermal ... -
An international review of occupant-related aspects of building energy codes and standards
(Peer reviewed; Journal article, 2020)In light of recent research, it is evident that occupants are playing an increasingly important role in building energy performance. Despite the important role of building energy codes and standards in design, the ... -
Intrinsic instabilities of hydrogen and hydrogen/ammonia premixed flames: Influence of equivalence ratio, fuel composition and pressure
(Peer reviewed; Journal article, 2023)Premixed lean hydrogen-air flames exhibit instabilities due to hydrodynamic instabilities but also thermo-diffusive instabilities. However, in the case of ammonia/hydrogen blends, the effect of ammonia addition on instabilities ... -
Intrinsic thermoacoustic modes in an annular combustion chamber
(Peer reviewed; Journal article, 2020)Thermoacoustic instabilities originate from the interaction of unsteady heat release rate associated with flames and the acoustic modes of a combustor. A feedback loop not involving the natural acoustic modes has been ... -
Introducing Lignin as a Binder Material for the Aqueous Production of NMC Cathodes for Li-ion Batteries
(Peer reviewed; Journal article, 2022)By enabling water-based cathode processing, the energy-intensive N-methyl-2-pyrrolidone (NMP) recovery step can be eliminated, reducing the cost and environmental impact of LIBs. Aqueous processing of high capacity ... -
