1. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. LÄS MER
2. Galaxy evolution in extreme environments
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Interactions play a crucial role in determining how galaxies evolve in terms of their morphologies and star formation histories, since the majority of the known galaxies in the nearby Universe are found to exist in groups. Compact groups of galaxies are of particular interest as they contain a small number of galaxies in dense configurations and host repeated interactions between them, enabling us to capture signatures of these interactions (e.

3. Development of Spectroscopic Measurements for Raman and Thomson Scattering Diagnostics ——Applications in Combustion and Plasma
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. LÄS MER
4. Heavy-Duty Spark-Ignited Single Cylinder Engine Fueling System
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Forskning inom motorutveckling bedrivs för att möta kommande emissionskrav och samtidigt minska bränsleförbrukningen. Kommande förbud mot dieseldrivna fordon planeras i flera städer runt om i världen. Alternativa bränsle som exempelvis naturgas ses som en lovande ersättning även för tunga fordon. LÄS MER
5. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+
Master-uppsats, KTH/MekanikSammanfattning : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. LÄS MER
