A unified multilevel framework of upscaling and domain decomposition
(International Center for Numerical Methods in Engineering (CIMNE), 2010)We consider multiscale preconditioners for a class of massconservative domaindecomposition (MCDD) methods. For the application of reservoir simulation, we need to solve large linear systems, arising from finitevolume ...Conference object 
Upscaled modeling of CO2 injection and migration with coupled thermal processes
(Elsevier, 2013)A practical modeling approach for CO2 storage over relatively large length and time scales is the verticalequilibrium model, which solves partially integrated conservation equations for flow in two lateral dimensions. ...Journal article 
Upscaling of Nonisothermal Reactive Porous Media Flow under Dominant Péclet Number: The Effect of Changing Porosity
(Society for Industrial and Applied Mathematics, 2016)Motivated by rockfluid interactions occurring in a geothermal reservoir, we present a twodimensional pore scale model of a thin strip consisting of void space and grains, with fluid flow through the void space. Ions in ...Journal article 

Value of different data types for estimation of permeability
(The University of Bergen, 20110601)The interrelation between sensitivity, nonlinearity and scale, associated with the inverse problem of identifying permeability from measurements of fluid flow, is considered. The gouverning equations for fluid flow in a ...Master thesis 
Vascular responses to radiotherapy and androgendeprivation therapy in experimental prostate cancer
(BioMed Central, 20120523)Background: Radiotherapy (RT) and androgendeprivation therapy (ADT) are standard treatments for advanced prostate cancer (PC). Tumor vascularization is recognized as an important physiological feature likely to impact on ...Peer reviewedJournal article 
Verifisering av ein tredimensjonal bølgemodell ved hjelp av eksperimentelle data
(The University of Bergen, 2001)Master thesis 
Vertically averaged equations with variable density for CO2 flow in porous media
(Springer, 201503)Carbon capture and storage has been proposed as a viable option to reduce CO 2 emissions. Geological storage of CO 2 where the gas is injected into geological formations for practically indefinite storage, is an ...Journal article 
Vertically Averaged Models for CO2 Storage in Porous Media
(The University of Bergen, 2008)Master thesis 
Volume preserving numerical integrators for ordinary differential equations
(The University of Bergen, 20131108)Doctoral thesis 
Wave breaking in long wave models and undular bores
(The University of Bergen, 20151218)Bores are a well known phenomena in fluid mechanics, although their occurrence in nature is relatively rare. The circumstances in which they occur is usually when a tidal swell causes a difference in surface elevation ...Master thesis 
Weak solutions and convergent numerical schemes of BrennerNavierStokes equations
(20150120)Lately, there has been some interest in modifications of the compressible NavierStokes equations to include diffusion of mass. In this paper, we investigate possible ways to add mass diffusion to the 1D NavierStokes ...Research report 
The Whitham Equation as a model for surface water waves
(Elsevier, 201508)The Whitham equation was proposed as an alternate model equation for the simplified description of unidirectional wave motion at the surface of an inviscid fluid. As the Whitham equation incorporates the full linear ...Journal article
