FSI investigation of a hydrofoil
(Master thesis, 2017)Due to the changes in electricity production where intermittent energy sources like wind and solar power increase their ratio, a stabilizing energy source is required, which hydropower plants provides. The stabilization ... -
FSI Simulation of a Guide Vane
(Master thesis, 2016)When fluid flows over an object, vortexes can develop, depending on the geometry of the object and conditions in the flow. Unwanted vortexes can be generated around both stay vanes and guide vanes in a hydropower plant, ... -
FSI-analysis of a Francis turbine
(Master thesis, 2012)Sediment erosion in Francis turbines is a big problem in hydropower plants in and around the Himalayas. The sediment composition in the rivers contains high levels of the hard mineral quarts. When the sediments enter the ... -
Fuel and Equivalence Ratio Effects on Transfer Functions of Premixed Swirl Flames
(Peer reviewed; Journal article, 2020)This paper reports on the effects of fuel and equivalence ratio on the response of lean premixed swirl flames to acoustic perturbations of the flow, at atmospheric pressure. The response is analyzed using flame transfer ... -
Fuel characterization and thermal degradation kinetics of biomass from phytoremediation plants
(Journal article; Peer reviewed, 2020)Biomass obtained from phytoremediation energy crops Miscanthus x giganteus and Sida hermaphrodita planted on different soils contaminated with heavy metals was thermogravimetrically studied and kinetically analyzed, assuming ... -
Full Plant Scale Analysis of Natural Gas Fired Power Plants with Pre-Combustion CO2 Capture and Chemical Looping Reforming (CLR)
(Journal article; Peer reviewed, 2017)In this study, first of its kind complete plant scale integration of pre-combustion CO2 capture method with Chemical Looping Reforming (CLR) of Natural Gas (NG), Water Gas Shift (WGS) process, CO2 capture and CO2 compression ... -
Full-Spectrum High-Resolution Modeling of the Dielectric Function of Water
(Journal article, 2020)In view of the vital role of water, exact knowledge of its dielectric function over a large frequency range is important. We report on currently available measurements of the dielectric function of water at room temperature ... -
Fully resolved simulations of single char particle combustion using a ghost-cell immersed boundary method
(Journal article; Peer reviewed, 2018)A novel ghost‐cell immersed boundary method for fully resolved simulation of char particle combustion has been developed. The boundary conditions at the solid particle surface, such as velocity, temperature, density, and ... -
Fundamental mechanisms of density wave oscillations and the effect of subcooling
(Master thesis, 2011)Boiling two-phase flow is found in many industrial applications such as boiling water reactors, two-phase flow heat exchangers and refrigeration systems. The physics of two-phase gas-liquid flow may lead to undesirable ... -
Fundamental Modeling of a Membrane Reactor with in Situ Hydrogen Separation and Combustion
(Journal article; Peer reviewed, 2013)In this work we consider a membrane reactor with catalytic steam methane reforming and/or water gas shift on the feed side, hydrogen separation and direct combustion of hydrogen on the permeate side, where the ultimate ... -
Fundamentals of natural gas processing - hydrocarbon dew point meter modelling
(Master thesis, 2014)When natural gas is taken from the reservoir it needs to be refined by removing liquid and other impurities in order to prevent hydrate formation in the pipelines and to keep the gas within sales specifications. Scrubbers, ... -
Funksjonstest av ventilasjonsvifte
(Master thesis, 2010)Økt fokus på energibruk i bygninger gjør det interessant å sjekke virkningsgrad til vifter for ventilasjonsformål som mistenkes å være lav. 15 \% av energien i nye bygg går i dag til å drive ventilasjonsvifter. Slik designen ... -
Further Development of FLNG Concept Based on Offshore Associated Gas
(Master thesis, 2015)This report assesses the technical and economic feasibility of associated gas utilization, based on deepwater oil production in Brazilian fields. In many cases, offshore oil production involves significant amounts of ... -
Further development of solutions for subsea liquid hydrocarbon processing
(Master thesis, 2016)Subsea processing has grown into a common vision for the industry known as All subsea . Process solutions presented take a big step towards this vision, and will be a significant extension from today s solutions. The ... -
Furthering the representation of causal chains between water and land use in Life Cycle Assessment
(Master thesis, 2015)In this thesis the causal chains between deforestation and increased flood impacts are assessed for expanding the life cycle impact assessment (LCIA) methodology. Until recently the impact categories water use and land use ... -
Future changes in consumption: The income effect on greenhouse gas emissions
(Peer reviewed; Journal article, 2021)The scale and patterns of household consumption are important determinants of environmental impacts. Whilst affluence has been shown to have a strong correlation with environmental impact, they do not necessarily grow at ... -
Future dust concentration over the Middle East and North Africa region under global warming and stratospheric aerosol intervention scenarios
(Peer reviewed; Journal article, 2023)The Middle East and North Africa (MENA) region is the dustiest region in the world, and understanding the projected changes in the dust concentrations in the region is crucial. Stratospheric aerosol injection (SAI) ... -
