Et kritisk og konstruktivt blikk på naturfaget i norsk skole
(Chapter, 2021)Dette kapitlet retter et kritisk, men konstruktivt blikk på naturfag, og foretar en gjennomgang av naturfag og naturfagdidaktikk innen forskning og i praksis. Kapitlet starter med å beskrive og diskutere naturfagets ... -
Features concerning capillary pressure and the effect on two-phase and three-phase flow
(Chapter, 2008-04-30)The effect of capillary pressure related to immiscible WAG (Water Alternate Gas) is studied by use of a numerical simulator. The capillary pressure is found to have a significant effect on the pressure gradient and the ... -
Fluid Flow Properties of WAG Injection Processes
(Chapter, 2008-04-30)Immiscible water-alternating-gas (IWAG) experiments performed on equilibrated fluids are summarised together with the corresponding two-phase gas-oil and water-oil displacements. Experimental studies at reservoir condition ... -
Modelling of vented dust explosions – empirical foundation and prospects for future validation of CFD codes
(IChemE Symposium Series;154, Chapter; Peer reviewed, 2008)Explosion venting is the most frequently used method for mitigating the effects from accidental dust explosions in the process industry. Optimal design of vent systems and credible execution of risk assessments in powder ... -
Multimodal analysis of gas-oil intermittent structures in co-current horizontal flow
(Chapter, 2020)Multiphase flow measurement aims to accurately quantify the flow rates of the fluids flowing through a pipe. Depending on the measurement principle, the accuracy can be heavily affected by the spatial distribution of flow ... -
Scattering from spheres and cylinders - revisited
(Chapter, 2006)Backscattering of sound from elastic spheres is commonly applied for calibration of acoustic systems. Measurements on the "form function" of various tungsten carbide spheres turned out not to match simulations based on ... -
Simplified modelling of explosion propagation by dust lifting in coal mines
(Chapter; Peer reviewed, 2007)Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of the propagating flame may sustain explosion propagation in coal mine galleries and other industrial facilities. The mechanisms ... -
Simulation of geomechanical effects of CO2 injection in cold aquifers with possibility of hydrate formation
(Chapter; Peer reviewed, 2011)The injection of CO2 in saline aquifers can have a significant impact on the geochemistry and the geo-mechanics of the reservoirs. Due to this injection, minerals will dissociate in regions with low pH or precipitate in ... -
Simulation of hydrate dynamics in reservoirs
(Chapter; Peer reviewed, 2011)Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon dioxide ... -
Teaching Robust Argumentation Informed by the Nature of Science to Support Social Justice. Experiences from Two Projects in Lower Secondary Schools in Norway
(Chapter, 2020)This chapter suggests a set of design principles for science curricula that will enable students to produce evidence-based arguments expressing views related to their own interests. It is based on the assumption that the ...
