  1. 1. Combustibility study of resin for warm magnet coils used at CERN

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Juan Carlos Lopez Santiago; [2023]
    Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

  3. 2. Wildfire growth modelling in Sweden - a suitability assessment of available data

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

    Författare :Henrik Hagelin; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

    Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER

  4. 3. Flame Extensions Under Ceilings

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Martin Sturdy; [2023]
    Nyckelord :Flame length; curved ceiling; Technology and Engineering;

    Sammanfattning : In this Master thesis project the factors affecting flame extension under flat and curved ceilings have been investigated. An experimental campaign was carried out in Lund University’s Fire Lab using a propane gas burner and heptane pool fire in different positions and heat release rates within the setups. LÄS MER

  5. 4. YTBEHANDLADE TRÄELEMENT : En studie av brandskydd, bärförmåga, pris och miljöpåverkan av ytbehandlade träelement.

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Angelo Issa; Maher Machhadi; Mircea Barbu; [2021]
    Nyckelord :Timber; surface-treatment; fire-safety; load-bearing capacity; charring-rate; fire-retardant paint; fire-resistance; high-rise building.;

    Sammanfattning : The current Swedish building code (Boverkets Byggregler, BBR) is very strict regarding fire-safety in high-rise timber structures because of the heightened risk of fast flame spread or structural failure in case of fire. Fire safety solutions, that are used in timber structures must therefore be optimal to contain flames from spreading in the event of fire. LÄS MER

  7. 5. INTERMEDIATE-SCALE TESTS AND CONE CALORIMETER TESTS - FIRE BEHAVIOUR OF SELECTED FACADE MATERIALS

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tanja Cernosa; [2020]
    Nyckelord :Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

    Sammanfattning : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.
