A Numerical Study of Exercise Induced Laryngeal Obstruction using Fluid-Structure Interaction
(Master thesis, 2017-06-20)During inhalation, the pressure in the lungs decreases relative to the atmospheric air pressure, so that the atmospheric air is sucked into the lungs. During strenuous exercise, exposed individuals may experience that the ... -
A numerical study of flow field and particle deposition in nasal channels with deviant geometry
(Journal article; Peer reviewed, 2021)Deviant geometry of nasal channels results in significant changes to nasal aerodynamics that alter flow resistance, sensation, and the ability to filter aerosols. The invasive, operative modification of nasal geometry might ... -
A numerical study of nonlinear dispersive wave models with SpecTraVVave
(Peer reviewed; Journal article, 2017-03-02)In nonlinear dispersive evolution equations, the competing effects of nonlinearity and dispersion make a number of interesting phenomena possible. In the current work, the focus is on the numerical approximation of ... -
Numerical Study of the “End of the Vortex” Phenomenon in a Hydrocyclone Separator
(Peer reviewed; Journal article, 2011)The single‐phase flow field in a hydrocyclone was studied numerically using the LES turbulence model. The hydrocyclone geometry and flow conditions are in accordance with previous experimental work. An important phenomenon ... -
A numerical study of transport and spreading of gases from natural analogues of gas-seepage through the seafloor
(Peer reviewed; Journal article, 2009-02)Natural leakages of CO2 are reported in the literature at mid ocean ridges and CH4 seepages in hydrocarbon rich ares. These could potentially serve as natural analogues of leakages from CO2 storages. In this study we have ... -
Numerical study on the hydrodynamic background in coastal aquaculture dominated regions and corresponding interactions in the Yellow Sea
(Doctoral thesis, 2022-01-07)The Yellow Sea is an important region for aquaculture in China as the main production area for shellfish and seaweed. The aquaculture organisms sometimes can be the major group in a local ecosystem. e.g., in the Sanggou ... -

Numerisk modellering av grunne geotermiske systemer. Modellering og analyse av Komplett Arena, samt sammenligning av to ulike modelleringsverktøy
(Master thesis, 2017-12-14)Numeriske modelleringsverktøy har utviklet seg til å bli et viktig verktøy ved prosjektering av større geotermiske systemer. Korrekt anvendelse av slike verktøy sørger for at tilhørende simuleringsresultater gir et detaljert ... -
Numerisk modellering av varmeoverskudd i grunnvarmeanlegg – Konsekvenser og forebyggende tiltak
(Master thesis, 2018-06-21)The emission of greenhouse gases must be reduced to meet the objectives of The Paris Agreement. Geothermal heat pumps (GSHP) can reduce energy consumption and emission of greenhouse gases in the building sector. When an ... -
Numerisk og eksperimentell analyse av forankringskrefter for et semilukket oppdrettsanlegg
(Master thesis, 2021-06-01)Norsk havbruksnæringen genererer enorme verdier samtidig som den ståar ovenfor betydelige utfordringer knyttet til miljø, rømming og luseproblematikk. For å løse utfordringene er det behov for ny teknologi i bransjen. Et ... -
