Numerical modelling of crack initiation and propagation in rocks using the XFEM
(Master thesis, 2022)Denne masteroppgaven fokuserer på numerisk modellering av sprekkevekst i et bergartslignende materiale under enaksielt trykk ved å bruke den utvidete endelige element metoden (XFEM). Todimensjonale prøvestykker som inneholder ... -
Numerical modelling of damping for timber structures in Abaqus
(Master thesis, 2020)Demping er en egenskap som påvirker den dynamiske responsen til trekonstruksjoner. Det er imidlertid en vanskelig oppgave å representere virkelig demping numerisk. I denne oppgaven er numerisk modellering av demping for ... -

Numerical Modelling of Debris Flow Hazards using Computational Fluid Dynamics
(Master thesis, 2018)Debris flows are a natural hazard phenomenon that occur periodically in steep mountainous terrain and are typically triggered by heavy precipitation events. The flows are a highly mobile poorly graded mass of soil, rock, ... -
Numerical modelling of distinct ice lenses in frost heave
(Peer reviewed; Journal article, 2021)Frost heave happens when three conditions coincide: the temperature is below the normal freezing point of bulk water, the sub-cooled water is connected to a water reservoir, and the mechanical conditions of the soil allows ... -
Numerical modelling of downstream-migrating antidunes
(Journal article; Peer reviewed, 2017)A numerical model is presented that compute the geometrical dimensions and movement of downstream migrating antidunes. The model solves the Navier–Stokes equations together with the k-epsilon turbulence model to find the ... -
Numerical modelling of field test for crack risk assessment of early age concrete containing fly ash
(Journal article; Peer reviewed, 2018)The high-strength/high-performance concretes are prone to cracking at early age due to low water/binder ratio. The replacement of cement with mineral additives such as fly ash and blast-furnace slag reduces the hydration ... -
Numerical modelling of fin side heat transfer and pressure loss for compact heat recovery steam generators
(Master thesis, 2022)Ein fjerdedel av dei norske CO2 utsleppa i 2019 kom from olje- og gassproduksjon. For å redusere desse utsleppa har installasjon av damp-botnsyklusar blitt føreslege. På grunn av høge krav til vekt og storleik offshore må ... -
Numerical modelling of flow over spillways
(Master thesis, 2010)The spillway of Sarpfossen hydropower plant has been studied numerically and experimentally. The physical model was built in the Vassdragslaboratoriet at the Norwegian University of Science and Technology, NTNU. The model ... -
Numerical Modelling of Focussed Wave Hydrodynamics and Focused Wave-structure Interaction with REEF3D
(Master thesis, 2016)General irregular sea state can generate very steep waves which can induce unpleasant dynamic wave loading to the structures. Sometimes these wave loads exceed upper design limits of the structure thus resulting in the ... -
Numerical Modelling of Hydraulics and Sediment at the Headworks of Kali Gandaki A Hydropower Plant, Nepal
(Master thesis, 2020)The Kali Gandaki A Hydropower Plant (KGA) has been facing issues related to unfavourable flow conditions at intake and settling basins, thereby hindering the efficient settling of the sediments, as realized from the excessive ... -
Numerical modelling of hydraulics and sediment at the inlet location of Sediment Bypass Tunnel (SBT) - Test Case: Upper Arun Hydroelectric Project, Nepal
(Master thesis, 2020)The study aims to analyse the effects of sediment bypass tunnel inlet location on intake hydraulics and suspended sediment removal for a reservoir of Upper Arun Hydroelectric Project (UAHEP) using numerical modelling ... -
Numerical modelling of hydrodynamic responses of Ocean Farm 1 in waves and current and validation against model test measurements
(Peer reviewed; Journal article, 2021)With the continuous growing of the aquaculture industry and increasingly limited fish farming sites at close to shore areas both in Norway and worldwide, there is a need to develop fish farms suitable for aquaculture ... -
Numerical Modelling of Irregular waves and Irregular Wave Forces with REEF3D
(Master thesis, 2015)In this study, the irregular wave generation using the numerical model REEF3D is tested and validated. The testing for the empty wave tank is done in order to test the irregular wave generation and the propagation. The ... -
Numerical Modelling of Laterally Loaded Piles in PLAXIS 3D - A study on embedded pile and soil response in PLAXIS 3D under lateral load
(Master thesis, 2016)Embedded pile element in PLAXIS 3D is an efficient method for pile foundation modelling. The current project provides an overall study on the embedded pile and surrounding soil response in PLAXIS 3D. The finite element ... -
Numerical Modelling of Liquid-Rich Shale Wells: GOR Oscillations in Highly Undersaturated Fluids
(Master thesis, 2020)The unconventional petroleum resources have attracted significant attention throughout recent years. These resources are estimated to have reserves greater than those of conventional ones. Increasing energy demands and ... -
Numerical modelling of marine icing on offshore structures and vessels
(Master thesis, 2012)A numerical model for predicting icing on offshore structures and vessels has been developed and implemented. The model calculates the icing caused by freezing sea spray, and focuses on two distinct sources of spray - spray ... -
Numerical Modelling of Migration Pattern of Salmon Smolts
(Master thesis, 2020)Bestanden av villaks synker. Det er flere årsaker til reduksjonen i laksebestanden, og en av disse er lakselus. Den kraftige økningen i lakseoppdrett har bidratt til en unaturlig konsentrasjon av lus. Oppførselen til ... -
