Auxiliary variables for 3D multiscale simulations in heterogeneous porous media
(Journal article, 2013-04-01)The multiscale control-volume methods for solving problems involving flow in porous media have gained much interest during the last decade. Recasting these methods in an algebraic framework allows one to consider them as ... -
Conforming, non-conforming and non-matching discretization couplings in discrete fracture network simulations
(Peer reviewed; Journal article, 2019)Simulations of fluid flow in naturally fractured rocks have implications for several subsurface applications, including energy storage and extraction, and waste disposal. We are interested in flow in discrete fracture ... -
Convergence of energy stable finite-difference schemes with interfaces
(Journal article; Peer reviewed, 2021)We extend the convergence results in Svärd and Nordström (2019) [7] for single-domain energy-stable high-order finite difference schemes, to include domains split into several grid blocks. The analysis also demonstrates ... -
Entropy stability for the compressible Navier-Stokes equations with strong imposition of the no-slip boundary condition
(Journal article; Peer reviewed, 2022)We consider the compressible Navier-Stokes equations subject to no-slip adiabatic wall boundary conditions. The main goal is to investigate stability properties of schemes imposing the no-slip condition strongly (injection) ... -
Entropy stable boundary conditions for the Euler equations
(Journal article; Peer reviewed, 2021)We consider the initial-boundary value Euler equations with the aim to derive boundary conditions that yield an entropy bound for the physical (Navier-Stokes) entropy. We begin by reviewing the entropy bound obtained for ... -
Entropy stable far-field boundary conditions for the compressible Navier-Stokes equations
(Journal article; Peer reviewed, 2024)We consider external compressible-flow problems with open boundaries. We begin by presenting the basic idea, namely the introduction of an infinite buffer zone around the computational domain, for the advection-diffusion ... -
Identification of subsurface structures using electromagnetic data and shape priors
(Journal article, 2015-03)We consider the inverse problem of identifying large-scale subsurface structures using the controlled source electromagnetic method. To identify structures in the subsurface where the contrast in electric conductivity can ... -
Large Eddy Simulations by approximate weak entropy solutions
(Journal article; Peer reviewed, 2022)We propose to use weak (averaged) entropy solutions in lieu of LES models. This approach unites the theory for shock capturing schemes and turbulence modelling. To achieve this, we identify a number of conditions (albeit ...
