Experimental study of hydrogen production using electrolyte nanofluids with a simulated light source
(Journal article; Peer reviewed, 2022)In this research, we conducted water electrolysis experiments of a carbon black (CB) based sodium sulfate electrolyte using a Hoffman voltameter. The main objective was to investigate hydrogen production in such systems, ... -
An Experimental Study of Methane Hydrate Growth and Dissociation in Porous Media
(Master thesis, 2015-06-01)Natural gas hydrate (NGH) is a solid phase consisting of water and natural gas. NGH represents a justified vast global energy resource, and is widespread in on-shore artic and sub-seafloor environments. Due to the worlds ... -
An Experimental Study of Methane Hydrates in Sandstone Cores
(Master thesis, 2015-05-31)Natural gas hydrates exist in large quantities around the world, located in the subsurface of permafrost and oceanic environments. Future energy harvest from production of methane gas encapsulated in natural gas hydrates ... -
An Experimental Study of Pool Fires and Validation of Different CFD Fire Models
(Master thesis, 2011-06-06)Computer programs developed to predict a possible fire scenario is today an important tool when working with fire safety. In this context different Computational Fluid Dynamics models, so called CFD models, where the domain ... -
An Experimental Study of Tertiary CO2 Injection Strategies in Fractured Limestone Rocks
(Master thesis, 2015-06-01)The experimental work within this thesis is a continued investigation of tertiary recovery by injection of supercritical CO2 and CO2-foam under miscible conditions for enhanced oil recovery in fractured limestone. Secondary ... -
An Experimental Study of the Influence of Major Damage of Flame Gap Surfaces in Flameproof Apparatus on the Ability of the Gaps to Prevent Gas Explosion Transmission
(Master thesis, 2010-06-10)Electrical apparatuses for use in the presence of explosive gas atmospheres have to be specially designed to prevent them from igniting the explosive gas. Flameproof design implies that electrical components producing ... -
An Experimental Study on the Influence of the Particle Size of Chemically Active Inhibitors in Turbulent Combustion
(Master thesis, 2012-06-01)Accidental gas leaks pose a great danger in the process industries. To reduce the consequences, should such a gas leak ignite, mitigating measures are needed. One such measure, involving the introduction of water deluge ... -
Experiments and Models of Carbon Black-based Nanofluids for Photothermal and Electrical Applications
(Doctoral thesis, 2023-06-26)Nanofluid er en type væske som inneholder spredte nanopartikler, som kan forbedre deres termiske og elektriske egenskaper sammenlignet med basevæsker. Dette har ført til omfattende bruksområder, som for eksempel solenergilagring. ... -
An explicit IMF By dependence on solar wind ‐ magnetosphere coupling
(Peer reviewed; Journal article, 2019)Presently, all empirical coupling functions quantifying the solar wind—magnetosphere energy—or magnetic flux conversion assume that the coupling is independent of the sign of the dawn-dusk component (B𝑦) of the Interplanetary ... -
Explicit tracking of CO2-flow at the core scale using micro-Positron Emission Tomography (μPET)
(Journal article; Peer reviewed, 2020)Safe subsurface sequestration of carbon dioxide (CO2) is becoming increasingly important to meet climate goals and curb atmospheric CO2 concentrations. The world-wide CO2 storage capacity in carbonate formations is ... -
