  1. 21. Tree Species Impact on Forest Fire Spread Susceptibility in Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Sara Sharon Jones; [2023]
    Nyckelord :Geography; GIS; Physical Geography; Forest Fire; Forest Fire Susceptibility; Sweden; logistic regression modelling; Earth and Environmental Sciences;

    Sammanfattning : Klimatförändringar förväntas leda till längre brandperioder och ökad brandrisk. I Sverige, där homogen produktionsskog utgör största delen av landskapet, finns ett behov av bättre förståelse för skogens mottaglighet för bränder för att kunna mildra risker. LÄS MER

  3. 22. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Wickramasooriyage Devmini Kularatne; [2022]
    Nyckelord :Oriented strand board; thermal decomposition; mechanical degradation; heat transfer modelling; Technology and Engineering;

    Sammanfattning : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. LÄS MER

  4. 23. A Comparative Study of Fires in Corners and Along Walls

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Josef Utterfors; Adam Tegenfeldt; [2022]
    Nyckelord :Fire; wall; corner; hot gas layer; flame height; plume temperature; Technology and Engineering;

    Sammanfattning : The topic of fires in corners and along walls has been studied previously, however, two different studies conducted in 1987 and 2018 respectively, produced conflicting results regarding plume temperature for fires along walls, as well as hot gas layer temperature for both fires in corners and along walls. This thesis seeks to add data and clarification about fires in corners and along walls. LÄS MER

  5. 24. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Birgir Steinn Hermannsson; [2022]
    Nyckelord :;

    Sammanfattning : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. LÄS MER

  7. 25. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :David Aronsson Edström; Oskar Lundberg; [2022]
    Nyckelord :3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Sammanfattning : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. LÄS MER
