Fluctuation-Dissipation Theorems for Multiphase Flow in Porous Media
(Peer reviewed; Journal article, 2022)A thermodynamic description of porous media must handle the size- and shape-dependence of media properties, in particular on the nano-scale. Such dependencies are typically due to the presence of immiscible phases, contact ... -
Fluctuations of sensorimotor processing in migraine: A controlled longitudinal study of beta event related desynchronization
(Journal article; Peer reviewed, 2019)Background The migraine brain seems to undergo cyclic fluctuations of sensory processing. For instance, during the preictal phase, migraineurs experience symptoms and signs of altered pain perception as well as other ... -
Flue Gas Recirculation for the Silicon Process
(Doctoral theses at NTNU;2023:135, Doctoral thesis, 2023)Metallurgical-grade silicon is a critical material for modern society. It is used as an alloying agent in aluminium alloys, feedstock for silicones, photovoltaics and electronics. Silicon is produced by carbothermal reduction ... -
Fluefiske.net - iphone variant av ordinær webside
(Bachelor thesis, 2010)Denne rapporten viser hvilke utfordringer man står ovenfor og hvor nært man kan komme en iPhone applikasjon i form av en webside. Dette er på mange måter en ny måte å tenke på for utviklere funksjonelt sett fordi ... -
Fluid conditioning system for subsea wellstream compression

Fluid diffusion in cracked composite laminates – Analytical, numerical and experimental study
(Journal article; Peer reviewed, 2018)Composite structural components are often subjected to service loads that cause cracks in off-axis layers, without compromising the load bearing capability of the structure. In marine or humid environments fluid ingress ... -
Fluid Displacement in a 2D DFN Fracture: Time Integration of the Interface Position
(Journal article; Peer reviewed, 2021) -
Fluid Flow and Leakage Assessment Through an Unlined/Shotcrete Lined Pressure Tunnel: A Case from Nepal Himalaya
(Peer reviewed; Journal article, 2021)The use of unlined/shotcrete lined pressure tunnels and shafts are cost-efective solutions for a hydropower project and are being implemented worldwide. To implement this concept, the ground conditions at the area of concern ... -
Fluid flow in steady and oscillatory lid-driven square cavities
(Peer reviewed; Journal article, 2017)This paper presents numerical simulations of steady and oscillatory lid-driven cavity flow at different Reynolds numbers with a fixed aspect ratio of 1:1. A projection method (P2 pressure correction method) is applied to ... -
Fluid flow properties of the Wilhelmøya Subgroup, a potential unconventional CO2 storage unit in central Spitsbergen
(Journal article; Peer reviewed, 2018)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
Fluid flow through 3D-printed particle beds: a new technique for understanding, validating, and improving predictability of permeability from empirical equations
(Peer reviewed; Journal article, 2020)The application of 3D technology for fabrication of artificial porous media samples improves porous media flow studies. The geometrical characteristics of a porous media pore channel: the channel shape, size, porosity, ... -
Fluid Heterogeneity in Tight Unconventional Reservoirs
(Doctoral theses at NTNU;2020:270, Doctoral thesis, 2020)This thesis deals primarily with layer-wise fluid heterogeneity in tight unconventional reservoirs. The industry has almost exclusively assumed that the fluid system within a well-box, i.e. contributing production to a ... -
Fluid Inclusions in Quartz and their potential for forming a Porphyry-Cu-Mo-Deposit in the Kleivan Granite, South Norway
(Master thesis, 2012)AbstractThe Kleivan granite is an oval granite of about 20 km2 situated near Lyngdal, south Norway. Samples from the quartz veins in the top of the magma chamber have been collected to investigate whether Mo might have ... -
A fluid mechanic view on urban wind energy
(Doctoral theses at NTNU;2022:283, Doctoral thesis, 2022)The world energy demand is rising with an increasing need for renewable and sustainable energy sources. Wind energy plays a key role in this transition. Urban areas are largely unexploited for wind energy extraction. Urban ... -
Fluid Meniscus Algorithms for Dynamic Pore-Network Modeling of Immiscible Two-Phase Flow in Porous Media
(Peer reviewed; Journal article, 2021)We present in detail a set of algorithms for a dynamic pore-network model of immiscible two-phase flow in porous media to carry out fluid displacements in pores. The algorithms are universal for regular and irregular pore ... -
Fluid Parameter Identification for Underwater Snake Robots
