Modelling of a Hydro Power Station in an Island Operation
(Journal article; Peer reviewed, 2017)There is a strong focus on new renewable energy sources, such as, solar power, wind energy and biomass, in the con-text of reducing carbon emissions. Because of its maturity, hydropower is often overlooked. However, there ... -
Modelling of ash melts in gasification of biomass
(Doctoral dissertations at the University of South-Eastern Norway;120, Doctoral thesis, 2022-03-04)The need for advanced biofuels produced from sustainable sources is stressed, both on national and international level due to a global agreement to limit the Earth’s global warming. The major goals in the Norwegian agreement ... -
Modelling of fast fueling of pressurized hydrogen tanks for maritime applications
(Journal article; Peer reviewed, 2023)This paper studies fast fueling of gaseous hydrogen into large hydrogen (H2) tanks suitable for maritime applications. Three modeling methods have been developed and evaluated: (1) Two-dimensional computational fluid dynamic ... -
Modelling of gas explosions
(Doctoral theses at NTNU;2010:221, Doctoral thesis; Peer reviewed, 2010-12-03)The content of this thesis is a study of gas explosions in complex geometries and presentation and validation of a method for simulating flame acceleration and deflagration to detonation transition. The thesis includes a ... -
Modelling of hydrocarbon gas and liquid leaks from pressurized systems
(Master thesis, 2021)Safety is one of the most important aspects that should be guaranteed for all the employees of any industry. For oil and gas platforms, the first step will fall into the optimum design of depressurization systems for ... -
Modelling of the energy budgets at Imingfjell, Norway, using the Community Land Model (CLM4.5)
(Master thesis, 2020)Mountains are one of the most sensitive areas to climate change as they are biodiversity hotspots. One of the main problems in studying climate change for mountainous territories is the lack of meteorological data due to ... -
Modelling of Water Levels in a Reservoir using Modelica
(Journal article; Peer reviewed, 2020)The regulation of hydro power plants is influenced by amongst others reservoir capacity and the knowledge about how it is influenced by changes in in- and out?ow. The hydro power reservoir Aurdalsfjord has a small capacity ... -
Modelling temperature transition and co-digestion in VEAS biogas process
(Master thesis, 2021)Anaerobic digestion (AD) is a well-established way to stabilise concentrated sludge produced in wastewater treatment (WWT) plants. The benefit of the process is the production of biomethane and digestate that can be used ... -
Modelling the Emission Offseting Potential of Rooftop Solar Panels
(Master thesis, 2023)This study empirically investigates the emission-offsetting potential of rooftop solar panels in a group of cities across three continents. By use of experimental big data from the Google Environmental Insights Explorer ... -
Modelling the heat dynamics of a residential building unit: Application to Norwegian buildings.
(Journal article; Peer reviewed, 2014)The paper refers to the development of a continuous time mathematical heating model for a building unit based on the rst principles. The model is described in terms of the state space variables, and a lumped parameter ... -
Modelling the synchronisation control for a hydro power controller
(Peer reviewed; Journal article, 2021)This paper presents the modelling of a synchronisation control as used inside a typical hydro power controller for small hydro power plants. It was built using the open-source modelling language Modelica by use of the ... -
Modelling the System Dynamics of Islanding Asynchronous Generators
(Journal article; Peer reviewed, 2014-03)Asynchronous generators are often used for small hydro power stations with an installed power capacity of under 1MW. The reason for this is their robustness and low cost. In order do be able to produce active electrical ... -
Modelling the vegetation response to the 8.2 ka BP cooling event in Europe and Northern Africa
(Journal article; Peer reviewed, 2019)The 8.2 ka bp cooling event is assumed to be the most clearly marked abrupt climate event in the Holocene at northern mid‐ to high latitudes. In this study, we simulate the vegetation responses to the 8.2 ka bp climate ... -
Modelling Tool for Hydropower Systems, with Analysis and Design
(Doctoral dissertations at the University of South-Eastern Norway;173, Doctoral thesis, 2023-10-19)The increased use of renewable energy sources is due to an increasing global energy need, and to counter the effects of fossil fuels on the environment. Common renewable energy sources such as solar energy and wind energy ... -
