Numerical simulation of the nonlinear coupled jaulent-miodek equation by elzaki transform-adomian polynomial method
(Journal article; Peer reviewed, 2020)The Elzaki transform which is an integral transform used to obtain solutions of linear differential equations is coupled with Adomian polynomial to solve nonlinear coupled Jaulent-Miodek (JM) equation. The Adomian polynomial ... -
Numerical simulation of turbidity currents: a new perspective for small- and large-scale sedimentological experiments
(Master thesis, 2007)Turbidity currents are a variety of subaqueous sediment-gravity flows, in which the suspension of sediment by water turbulence produces a water-sediment mixture that is denser than the ambient water and hence flows due to ... -
Numerical Simulation Studies of the Long-term Evolution of a CO2 Plume in a Saline Aquifer with a Sloping Caprock
(Peer reviewed; Journal article, 2011-02-02)We have used the TOUGH2-MP/ECO2N code to perform numerical simulation studies of the long-term behavior of CO2 stored in an aquifer with a sloping caprock. This problem is of great practical interest, and is very challenging ... -
Numerical simulations of surface winds and precipitation in Iceland – Die zweite Aufgabe der theoretischen Meteorologie

Numerical simulations of the flow and plugging behaviour of hydrate particles
(Master thesis, 2010-05-06)Abstract The main hydrate mitigation used by the industry today is to avoid formation at all cost. Avoidance of hydrate formation is made possible by use of inhibitors such as methanol or glycol. These are so called ... -
Numerical solution of drift-diffusion and electrostatic potential equations for solar cells.
(Master thesis, 2018-06-22)This thesis gives an introduction to how solar panels work and some of the problems for solar cells that need to be solved. Further, it gives an introduction to some physical equations that describe the electrical behavior ... -

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 ... -
