Simulation of floating bodies using a combined immersed boundary with the level set method in REEF3D
(Chapter, 2017)The 6DOF algorithm implemented in the open-source computational fluid dynamics (CFD) model REEF3D is used to simulate a horizontal cylinder in heave motion around the free surface and the motion of a freely floating ... -
Simulation of flow around a Viking ship rudder.
(Master thesis, 2015)Computational fluid dynamics (CFD) is a numerical method of solving the Navier-Stokes equations for all points in a grid, or mesh. By performing this operation over multiple time steps, the resulting velocity and pressure ... -
Simulation of Flow Around an Oil Boom
(Master thesis, 2015)The interFoam solver is used in this thesis. This solver applies the VOF method to trace the interface between two fluids. This method and the interFoam solver is thoroughly discussed in this thesis. A convergence study ... -
Simulation of Fluid Flow Through Porous Rocks on Modern GPUs
(Master thesis, 2009)It is important for the petroleum industry to investigate how fluids flow inside the complicated geometries of porous rocks, in order to improve oil production. The lattice Boltzmann method can be used to calculate the ... -
Simulation of fluid flow through real microannuli geometries
(Journal article; Peer reviewed, 2020)Debonding of well cement towards casing or rock, i.e. microannuli formation, is a typical failure mode of cement barriers. Consequently, such microannuli may act as leak paths during leakages of downhole fluids such as ... -
Simulation of Fractures in Elastic Bodies by Using Locally Refined B-splines
(Master thesis, 2015)Fracture mechanics plays an important role in many different applications. When modeling fractures, singularities occur around the fracture tips. Another aspect that makes the modeling of fractures difficult, is the ... -
Simulation of freely-floating bodies in waves using a 6dof algorithm
(Chapter, 2017)Interactions between floating bodies and waves are found in several engineering applications like oil platforms or floating breakwaters. Floating bodies are strongly influenced by the free surface and the fluid structure ... -
Simulation of gas dehydration process with MEG using Aspen Plus
(Master thesis, 2019)Gassdehydrering offshore er essensielt for å oppnå spesifikasjonskravene for eksportgass, å etterkomme myndighetskrav og for å garantere effektiv og trygg transport i eksportgassledninger. Prosessen for å dehydrere gass ... -
Simulation of H2S Removal from Biogas Using Aspen Plus
(Master thesis, 2019)Biogass er en forbybar energikilde og kan brukes som en substitutt til naturgass. Biogass må renses før den kan oppgraderes til biometan. Komponenter som kan gjøre skade på prosessutstyret, som for eksempel hydrogen sulfid ... -
Simulation of heave-induced pressure oscillations in Herschel-Bulkley muds
(Journal article; Peer reviewed, 2017)Heave induces pressure oscillations when drilling offshore from floating rigs. A time-domain model is proposed to analyze and predict such pressure oscillations. The model considers the coupled dynamics of the mud and the ... -
Simulation of hydraulic transients of operation at two hydro power plants
(Master thesis, 2016)The energy production in Europe is heading towards a green shift. The energy produced be renewable sources such as solar and wind are increasing day by day. This does however lead to a few issues. The energy produced by ... -
Simulation of indoor climate in ZEB in relation to heating and cooling system
(Master thesis, 2014)The purpose of this thesis was to study how the heating-, cooling- and ventilation systems affected the temperature distribution between the different zones in a building. Powerhouse Kjørbo is equipped with central radiator ... -
Simulation of infrared avalanche photodiodes from first principles
(Journal article; Peer reviewed, 2017)The present article deals with device physics and modeling of an Hg0.28Cd0.72Te wide-area electron-initiated avalanche photodiode, with main input data extracted from first principles electronic structure codes. Due to the ... -
