1. Jetbrandtester och vätgas : En litteratur- och intervjustudie om försök med vätgasjetflammor
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Vätgas är en energibärare som kan vara en av pusselbitarna i omställningen till en mer klimatneutral värld. Infrastrukturen byggs ut, industrin växer och vätgasfordon blir vanligare. LÄS MER
2. Validering av KFX för vätgasjetflammor som träffar ytor
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : Regarding climate change and the future need för renewable energy, hydrogen is considered to be an important component in energy storage systems. However, the use of hydrogen is fraught with risk due to its chemical properties. This thesis deals with the problem of modelling heat transfer from hydrogen jet flames hitting surfaces. LÄS MER
3. Fire Risk and Hazard Analysis of Lithium-Ion Battery Technologies in Underground Facilities: A Literature Review
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : The past decades have seen an exponential growth of the lithium-ion battery (LIB) market as use of this high-energy storage has found applications in nearly every industry. The European Organization for Nuclear Research (CERN) is interested in implementing this technology within their underground network and this literature review is intended to assist with addressing fire and safety concerns.

4. Assessment of thermal radiation arithmetic's for jet flames : A study involving generic calculation methods concerning radiation from jet flames with the purpose to determine the safety distance for flame effects
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Jet flames are commonly used as flame effects in pyrotechnical shows, and are also a possible risk in industries that uses pressurised flammable gas. For these users it is important to make fire safety engineering calculations to minimise the risks. This project focus on jet flames that are used in pyrotechnic shows where, e.g. 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
