Numerical Modelling and Experiments on Sea Spray Icing
(Doctoral thesis at NTNU;2014:338, Doctoral thesis, 2014)Oil and gas activities in the cold seas are endangered by icing. Icing may occur when water spray or moisture is deposited on a vessel or offshore structure above sea level and the air temperatures is below the freezing ... -
Numerical Modelling and Model Reduction of Heat Flow in Robotic Welding
(Master thesis, 2007)The project includes a numerical model of heat flow in robotic welding. The modelling is done in finite element method, and afterwards exported to Matlab where the model will be linearized and model reduced. The ultimate ... -
Numerical modelling and photo-electrochemical characterization of dye sensitized solar cells
(Master thesis, 2017)Current-potential characteristics were recorded, and intensity modulated photocurrent spectroscopy (IMPS), intensity modulated photovoltage spectroscopy (IMVS), and electrochemical impedance spectroscopy (EIS) was performed ... -
Numerical modelling and simulation of floating oil storage tanks considering the sloshing effect
(Master thesis, 2017)This report is performed at Department of Marine Technology at Norwegian University of Technology and Science (NTNU), which would also serve as part of the master thesis at Chalmers University of Technology (CTH). This ... -
Numerical modelling and simulations for lowering of an offshore wind turbine tripod
(Master thesis, 2016)Offshore wind industry is developing very fast. Transport and installation are important aspects for reducing the life-cycle cost of offshorewind farms. In shallowwaters (10-30mof water depths), monopile foundations have ... -
Numerical Modelling for Fluid-Structure Interaction of Aquaculture Collar Structures using a Beam Model
(Master thesis, 2019)I denne oppgaven brukes en 3-dimensjonal strålemodell for fiske merd strukturen, og Newmark-metoden er vedtatt for tidintegrasjon av strukturell dynamisk analyse. For å verifisere og validere strukturløsningen utviklet i ... -
Numerical modelling of a Czochralski furnace with active cooling jacket - Optimization of quality and througput
(Master thesis, 2015)In the single crystal silicon Czochlarski process, pull rate has a great impact on its production. More and more people put their eyes on optimizing the structure of Cz furnace to increase the pull rate, but experiments ... -
Numerical Modelling of a Pile Model Test with Focus on Small-strain Stiffness
(Master thesis, 2015)This thesis investigated the dynamic characteristics of a 1:20 scale model of a monopile offshore wind turbine foundation, and performed numerical modelling of the model pile using the FEM-software PLAXIS 3D. The build-up ... -
Numerical modelling of air entrainment: In hydraulic engineering
(Doctoral theses at NTNU;2021:62, Doctoral thesis, 2021)Air entrainment in water flows is a natural phenomenon prone to take place when energy is dissipated in flowing water. In nature, air entrainment appears as white water in waterfalls or in waves breaking on the beach. ... -
Numerical Modelling of an Innovative Conical Pile Head Breakwater
(Peer reviewed; Journal article, 2022)When moderate wave activity at the shoreline is acceptable, pile breakwaters can serve as an alternative to conventional breakwaters. Increasing the size of the pile breakwater in the vicinity of the free surface increases ... -
Numerical Modelling of Arctic Coastal Erosion Due to Breaking Waves Impact Using REEF3D
(Chapter, 2017)In the present study, numerical modelling breaking waves over a slope and the resulting erosion in the arctic region is presented. The study is performed with the open-source computational fluid dynamics (CFD) model REEF3D. ... -
Numerical Modelling of Arctic Coastal Hydrodynamics and Sediment Transport
(Master thesis, 2016)Coastal areas are experiencing an increase in human population and activities, both in temperate and in Arctic areas. This change in the coastal areas requires that the areas are safe and reliable in order to not put human ... -
Numerical Modelling of Arctic Costal Erosion
(Doctoral theses at NTNU;2023:213, Doctoral thesis, 2023)Arctic coastal erosion is a growing concern as global climate change affects the planet. Unlike low-latitude and mid-latitude coastal areas, the sediments along Arctic coastlines are often frozen, even during summer. It ... -
Numerical modelling of bank failures during reservoir draw-down
(Journal article; Peer reviewed, 2018)Numerical algorithms are presented for modeling bank failures during reservoir flushing. The algorithms are based on geotechnical theory and the limit equilibrium approach to find the location and the depth of the slides. ... -
Numerical modelling of Bingham fluid flow and particle transport in a rough-walled fracture
(Master thesis, 2013)Drilling operations may encounter mud loss which becomes especially aggravated in naturally fractured formations. The dynamics of fluid loss is a complex process, affected by both the rheology and the composition of the ... -
Numerical Modelling of Brittle Failure in Ice Structures
(Master thesis, 2014)The main purpose of this Master's thesis is to use finite element method to investigate if brittle failure in sea ice can be described in a force-displacement history. Four implemented material models in LS-Dyna are taken ... -
Numerical Modelling of Coastal Erosion using MIKE21
(Master thesis, 2013)Coastal erosion is a problem that is increasingly being faced world over. This erosion is important not only in tropical areas but also in the Arctic region. Many numerical models exist today to predict coastal erosion ... -
