Numerical solution of the the time-dependent Schrödinger equation.
(Master thesis, 2018-06-22)On the atomic scale the time-dependent Schrödinger equation is used but for systems with three or more particles like the helium atom it is not possible to solve the Schrödinger equation exactly. The motivation here is to ... -
Numerical solutions of two-phase flow with applications to CO2 sequestration and polymer flooding
(Doctoral thesis, 2014-12-19)This thesis addresses challenges related to mathematical and numerical modeling of flow in porous media. To address these challenges, two applications are considered: firstly, counter-current two-phase flow in a heterogeneous ... -
Numerical studies of rotationally controlled lock exchange flow over a sill
(Master thesis, 2018-06-21)Numerical experiments of lab scale on dense water inflow in a channel initially filled with freshwater, where a sill is present. The focus has been on the dynamics at the top of the sill, and especially on the behavior of ... -

A numerical study of ammonia dispersion in an industrial area with the CFD tool FLACS
(Master thesis, 2018-06-20)As the use of ammonia increases, knowledge about dispersion patterns and dispersion tendencies is of enhanced importance. Due to its toxic nature, very few realistic experiments of ammonia dispersion in complex situations ... -
A Numerical Study of Empty Nose Syndrome: an Evaluation of Nasal Aerodynamics
(Master thesis, 2018-06-20)Empty nose syndrome (ENS) is a rare complication of nasal surgery done to enlarge the internal nasal channels. The feeling of nasal obstruction despite patency is one of the most common symptoms among ENS patients. This ... -
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 ... -
