Numerical modeling of fracture initiation using plasticity models
(Master thesis, 2018)Nowadays hydraulic fracturing is a key part of the oil and gas industry to enhance the field's production. Therefore, is important to understand how fractures initiate and how to extract important information from them for ... -
Numerical Modeling of Hydrogen Fluoride Adsorption
(Master thesis, 2021)Produksjonsmengden av aluminium øker for hvert år. For å møte etterspørselen, øker aluminiumsverk spenningen i elektrolysecellene for å øke produksjonen, men også den økonomiske gevinsten. En bi-effekt av dette er økt ... -
Numerical modeling of liquefaction and its impact on anchor piles for floating offshore structures
(Journal article; Peer reviewed, 2019)Anchor piles and suction anchors have been used for anchoring different types of offshore structure in the past four decades. The recent growing interest and demand for wind energy has motivated the industry to evaluate ... -
Numerical modeling of nonstationary hydrodynamic forces and induced motions of a coupled offshore floating installation system
(Peer reviewed; Journal article, 2022)Offshore installations always involve multi-body systems in which the hydrodynamic and mechanical interactions are complicated for the properties keep changing under certain operation procedures. Float-over deck (FOD) ... -
Numerical modeling of perforated plates in oscillating flow
(Journal article; Peer reviewed, 2019)Perforated plates, relevant for several marine applications, are experimentally and numerically investigated. The numerical investigations are performed using a presently developed Navier–Stokes solver. Several comparison ... -
Numerical modeling of pool spreading, heat transfer and evaporation in liquefied natural gas (LNG)
(Master thesis, 2011)This master's thesis is a continuation of previous theses written at ComputIT AS. It treats heat transfer to LNG pools boiling on water through two heat transfer models, LNGSIM1 and LNGSIM2. LNGSIM1 utilizes heat transfer ... -
Numerical Modeling of Power Take-Off Damping in an Oscillating Water Column Device
(Journal article; Peer reviewed, 2015)An Oscillating Water Column (OWC) is a wave energy converter consisting of a partially submerged chamber with an air column over the water column. The work done by the air column under excitation by the incident waves is ... -
Numerical Modeling of Radial Fracturing of Cement Sheath Caused by Pressure Tests
(Chapter, 2019)To achieve an acceptable level of zonal isolation, well integrity should be guaranteed in hydrocarbon production and geological CO2 sequestration. Well pressure test can cause different types of failures in the well system ... -
Numerical Modeling of Swelling Rock
(Master thesis, 2010)This master thesis is focusing on numerical modeling of a swelling rock called anhydrite. If water gets in contact with the rock anhydrite (CaSO4) it transforms into gypsum (CaSO4•2H2O). This chemical process can result ... -
Numerical Modeling of the Effects of Toe Configuration on Throughflow in Rockfill Dams
(Peer reviewed; Journal article, 2021)The rockfill toe structure situated within the downstream slope of rockfill dams is an integral part of a defense mechanism safeguarding the dam structure in throughflow situations. Recent studies have concluded that the ... -
Numerical modeling of the hydraulic blade pitch actuator in a spar‐type floating wind turbine considering fault conditions and their effects on global dynamic responses
(Peer reviewed; Journal article, 2020)This paper deals with numerical modeling of the hydraulic blade pitch actuator and its effect on the dynamic responses of a floating spar‐type wind turbine under valve fault conditions. A spar‐type floating wind turbine ... -
Numerical Modeling of the Interaction of Moving Fish Nets and Fluid
(Peer reviewed; Journal article, 2022)The significant difference in length scales between the flow around a moving fish net and the flow around each twine of the net prevents the resolution of the complete structure within a discrete fluid domain. In this ... -
