An Approach for Investigation of Geochemical Rock-Fluid Interactions
Bringedal, Carina; Berre, Inga; Radu, Florin A. (Conference object, 2014)Geochemistry has a substantial impact in exploiting of geothermal systems. When water is injected in a geothermal reservoir, the injected water and in-situ brine have different temperatures and chemical compositions and ... -
Influence of natural convection in a porous medium when producing from borehole heat exchangers
Bringedal, Carina; Berre, Inga; Nordbotten, Jan Martin (Peer reviewed; Journal article, 2013-08)Convection currents in a porous medium form when the medium is subject to sufficient heating from below (or equivalently, cooling from above) or when cooled or heated from the side. In the context of geothermal energy ... -
Linear and nonlinear convection in porous media between coaxial cylinders
Bringedal, Carina; Berre, Inga; Nordbotten, Jan Martin; Rees, D. Andrew S. (Peer reviewed; Journal article, 2011)We uncover novel features of three-dimensional natural convection in porous media by investigating convection in an annular porous cavity contained between two vertical coaxial cylinders. The investigations are made using ... -
Linear and Nonlinear Convection in Porous Media between Coaxial Cylinders
Bringedal, Carina (Master thesis, 2011-05-02)In this thesis we develop a mathematical model for describing three-dimensional natural convection in porous media filling a vertical annular cylinder. We apply a linear stability analysis to determine the onset of convection ... -
Modeling of heat transfer in porous media in the context of geothermal energy extraction
Bringedal, Carina (Doctoral thesis, 2015-10-02)This dissertation concerns mathematical modeling related to heat transfer in the subsurface relevant for geothermal energy extraction. Two applications are considered: First, natural convection in a homogeneous porous ... -
Structure and Forcing of Observed Exchanges across the Greenland–Scotland Ridge
Bringedal, Carina; Eldevik, Tor; Skagseth, Øystein; Spall, Michael A.; Østerhus, Svein (Peer reviewed; Journal article, 2018)The Atlantic meridional overturning circulation and associated poleward heat transport are balanced by northern heat loss to the atmosphere and corresponding water-mass transformation. The circulation of northward-flowing ... -
Upscaling of Nonisothermal Reactive Porous Media Flow under Dominant Péclet Number: The Effect of Changing Porosity
Bringedal, Carina; Berre, Inga; Pop, Iulio Sorin; Radu, Florin A. (Peer reviewed; Journal article, 2016)Motivated by rock-fluid interactions occurring in a geothermal reservoir, we present a two-dimensional pore scale model of a thin strip consisting of void space and grains, with fluid flow through the void space. Ions in ...
