(Journal article; Peer reviewed, 2017) -
Numerical Simulation of Nonholonomic Dynamics
(Master thesis, 2006)We study the numerical integration of nonholonomic problems. The problems are formulated using Lagrangian and Hamiltonian mechanics. We review briefly the theoretical concepts used in geometric mechanics. We reconstruct ... -
Numerical simulation of piggyback pipelaying under current loadings
(Peer reviewed; Journal article, 2023)For piggyback pipelaying operations, current-induced force and its effect on the piggyback pipe have not been thoroughly studied. In the present study, an improved method in hydrodynamic load calculation and structural ... -
Numerical simulation of pore pressure in rock joints during pressure transient in an unlined hydropower tunnel
(Chapter, 2020)Recent experimental result shows that pressure transients of both short and long time periods; i.e. water hammer and mass oscillation; can travel into the rock mass of an unlined hydropower tunnel through rock joints. It ... -
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 slug flow in a micro-channel
(Master thesis, 2007)Multiphase dynamics and characteristics of slug flow in micro channels are investigated computationally by means of advanced numerical simulation methods. Although, due to its importance in many engineering and biomedical ... -

(Master thesis, 2018)This thesis consists of deriving and testing a numerical model for convection dominated solid-liquid phase transitions. Two scientific articles represents the main body of the thesis, but a short documentation of the work ... -
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 surge wave instability of long distance transport of multiphase flow
(Master thesis, 2018)The surge wave is an unstable flow phenomenon that may occur in the wet gas pipelines. The dramatic decrease in gas flow rate or the stopping of gas production due to other reasons would cause the liquid accumulation at ... -
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 ... -
