The main contribution ... -
Calculation of NOx Formation in a Swirl Burner
(Master thesis, 2008)This thesis embraces simulations of NOx emissions from a partially premixed 20 kW swirl burner. The simulations were carried out in the commercial computational fluid dynamics software FLUENT. The concept of partial premixing ... -
Calculation of Particle Resuspension Using Static and Dynamic Particle Models
(Master thesis, 2011)The aim of this master work was to investigate particle resuspension from fouled heatexchanger surfaces. In metallurgical industries, the waste gas may contain dust and particles which can deposit on the heat exchanger ... -
Calculation of Service and Sea Margins
(Master thesis, 2015)In this thesis two tankers owned by Kristian Gerhard Jebsen Skipsrederi (KGJS) were investigated. A method of calculating service and sea margins for different speeds has been developed. When a ship is in normal operation, ... -
Calculation of the interface curvature and normal vector with the level-set method
(Journal article, 2013)This article addresses the use of the level-set method for capturing the interface between two fluids. One of the advantages of the level-set method is that the curvature and the normal vector of the interface can be readily ... -
Calculation of wave forces due to extreme events in the coastal region using REEF3D - Beregning av bølgebelastninger fra ekstrem vær i kyst områder med REEF3D

Calculation of Wave Forces on Offshore Wind Turbine Jacket Sub-structures using REEF3D
(Master thesis, 2018)Throughout the thesis work, the literature on computational fluid dynamics is reviewed and governing equations of the REEF3D are studied. Two different laboratory experiment setups are replicated in the numerical wave tank. ... -
Calculation of Wave Forces on Structures using REEF3D
(Master thesis, 2012)Non-breaking wave forces on a cylindrical pile placed on a platform were calculated numerically by solving the 3D Navier Stokes equations in the Numerical Wave Tank of REEF3D. Initially, the numerical wave tank was validated ... -
Caledonian structural, metamorphic and magmatic evolution of the Rödingsfjället Nappe Complex
(Master thesis, 2022)Rödingsfjälldekkekomplekset og Helgelanddekkekomplekset utgjør de to store komponentene i øverste allokton og består av bergarter med både oseanisk og kontinental affinitet som representerer den ytterste marginen av ... -
Calibration and development of a numerical method for frost protection
(Master thesis, 2019)Frost heave and spring thaw can be critical contributors to pavement deterioration in seasonal frost regions. Several numerical programs are available to predict frost penetration depth, but the lack of fixed material ... -
Calibration and uncertainty analysis of pressure sensors used for dynamic measurements
(Master thesis, 2017)Dynamic calibration of pressure sensors is challenging. Often, steady-state calibration is applied on pressure sensors used to measure dynamical measurements. Steady-state calibration does not represent the dynamic behavior ... -
Calibration and validation of fully LiDAR-derived 2D hydraulic models: Integrating SAR imagery and observed water surface elevations
(Master thesis, 2023)Flom er et utbredt og kostbart fenomen som påvirker millioner av mennesker. For å redusere virkningene av flom har utviklingen av flomsonekart blitt avgjørende da de fungerer som verdifulle verktøy i flomhåndtering. ... -
The calibration challenge when inferring longitudinal track profile from the inertial response of an in-service train
