  1. 1. Skalningseffekter av medelstora pölbränder i syrereducerad miljö

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tim Hemel; Philip Frenander; [2024]
    Nyckelord :Sökord: syrereducerad atmosfär; medelstora pölbränder; skalningseffekter. Key words: hypoxic air; oxygen reduced atmosphere; medium pool fire; scaling effects; LOC; yields.; Technology and Engineering;

    Sammanfattning : This bachelor's thesis focuses on how scaling the pool diameter affects flammable liquids in an oxygen reduction system (ORS). This topic in the study of pool fire behavior in hypoxic air has been only lightly discussed in previous literature. Therefore, the goal of this thesis work is to further broaden the understanding of hypoxic air. LÄS MER

  3. 2. Utvärdering av tunnelbrandsmodeller

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Johanna Gondinger; Alva Larsson; [2024]
    Nyckelord :Tunnelbränder; FDS; handberäkning; branddynamik; brandexperiment Tunnel fires; CFD; hand calculations; fire dynamics; fire experiment; Technology and Engineering;

    Sammanfattning : The purpose of this study was to investigate the predictive capabilities of hand-calculation methods and simulations using FDS in understanding the behavior of a tunnel fire in terms of temperature and incident radiation. Additionally, the study aimed to examine the repeatability of a large-scale fire experiment. LÄS MER

  5. 4. Effekten av släcksprayer vid brandtillbud

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Casper Flensburg; Axel Kriborg; [2022]
    Nyckelord :Brandsläckare; släckspray; släckprodukt; Taerosol; Housgard; Technology and Engineering;

    Sammanfattning : This report investigates the impact of extinguishing sprays on residential fires, these sprays are a relatively new category of extinguishing equipment and therefore their actual effect on fires is generally unknown. Taking several factors such as human behavior and user error into account the report aims to give a comprehensive picture of potential risks and dangers connected to the usage of these products.
