1. Analogical reasoning in science education : - connections to semantics and scientific modelling in thermodynamics
Sammanfattning : Analogiskt tänkande är en central kognitiv förmåga som vi använder i vardagslivet, såväl som i mer formella sammanhang, såsom i forskning och undervisning. Föreliggande avhandling behandlar hur analogier och analogiskt tänkande, uppmärksamhet på semantik och förståelse för vetenskaplig modellering kan användas för att hantera utmaningar i naturvetenskapsundervisningen, särskilt inom området termodynamik.

2. Modelling of Solid Oxide Fuel Cells Applied to the Analysis of Integrated Systems with Gas Turbines
Sammanfattning : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. LÄS MER
3. The Underground as a Storage Facility. Modelling of Nuclear Waste Repositories and Aquifer Thermal Energy Stores
Sammanfattning : The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. LÄS MER
4. Thermodynamic Studies of the Fe-Pt System and “FeO”-Containing Slags for Application Towards Ladle Refining
Sammanfattning : In the present work, the thermodynamic activites of ironoxide, denoted as "FeO" in the slag systems Al2O3-"FeO", CaO-"FeO", "FeO"-SiO2, Al2O3-"FeO"-SiO2, CaO-"FeO"-SiO2and "FeO"-MgO-SiO2were investigated by employing the gasequilibration technique at steelmaking temperatures. Thestrategy was to expose the molten slag mixtures kept inplatinum crucibles for an oxygen potential, determined by aCO/CO2-ratio. LÄS MER
5. On Zero-dimensional Modelling of Combustion and NOx Formation in Diesel Engines
Sammanfattning : Diesel engine developers are facing major challenges when meeting future demands on NOx and particulate emissions. The exhausts after treatment systems are rapidly improving and the technologies available in a few years will be capable of cutting emission levels close to the demanded levels. LÄS MER
