Numerical Simulation of Ice-Rubble Mound Breakwater Interactions
(Master thesis, 2018)Offshore activity in energy production, fishing, shipping, and tourism is projected to increase in the Arctic and Sub- Arctic. This projected increase in offshore activity means the supporting coastal infrastructure needs ... -
Numerical Simulation of Interactions between Water Waves and a Moored-Floating Breakwater
(Chapter, 2018)Floating breakwaters offer a cost-efficient alternative to common emerged rubble mound breakwaters in deep water coastal areas or harbors with poor seabed conditions. Often, simple box type structures with a suitable mooring ... -
Numerical Simulation of Monopile Vibratory and Impact Installation in Saturated Sand
(Master thesis, 2021)Installasjon av offshore monopeler ved bruk av vibrolodd er antydet å ha flere fordeler sammenlignet med den konvensjonelle metoden ved bruk av fallodd. Det er usikkerhet knyttet til anslag av aksiell og lateral bæreevne ... -
Numerical simulation of sediment flushing in reservoirs
(Master thesis, 2018)As we saw, sediment can be a major factor in decreasing the lifespan, efficiency and profit of a hydropower plant. Countries and companies have to have countermeasures against the sedimentation, where high yields are ... -
Numerical Simulation of Submarine Slides in Bjørnafjorden Using Rheological Models
(Master thesis, 2019)The continuous development of the world creates the need for submarine transport and communication. Consequently, seafloor instabilities may create complications in the everyday life of humans. A sustainable design for the ... -
Numerical Simulation of Switch and Crossing Towards an Optimized Turnout Design
(Doctoral theses at NTNU;2018:210, Doctoral thesis, 2018)Switch and crossing (S&C) or turnout is a mechanical component within railway infrastructure that provides flexibility for train to switch from one track to another. However, such flexibility requires certain degree of ... -
Numerical Simulation of Wave Interaction with Submerged Porous Structures
(Peer reviewed; Journal article, 2020)The study of wave interaction with porous structures is essential as coastal structures are often porous in nature because of their prominent energy dissipation characteristics. The present work is focused on the numerical ... -
Numerical simulation of waves and local scour around vertical cylinders in a triangular arrangement using REEF3D
(Chapter, 2015)Coastal and offshore structures are generally supported by a group of cylinders. The stability of the structures can be threatened by sediment transport around the foundations. To explore this topic in detail, numerical ... -
A Numerical Solution for Modelling Mooring Dynamics, Including Bending and Shearing Effects, Using a Geometrically Exact Beam Model
(Peer reviewed; Journal article, 2021)During the operation of moored, floating devices in the renewable energy sector, the tight coupling between the mooring system and floater motion results in snap load conditions. Before snap events occur, the mooring line ... -
Numerical Study of Air Flow in Air Cavities for Pitched Wooden Roofs
(Master thesis, 2020)I Norge sees ofte eneboliger og andre typer småhus med skrå tretak. Luftede skrå tretak med et lufthulrom under takets tekning er av betydning for å sikre tørre forhold for takkonstruksjonen og samtidig holde lav temperatur ... -
