  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

  2. 2. Räddningsinsatser i trähusbyggnader - En intervjustudie om problematik och utmaningar med trähusbyggnader

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Samuel Vanberg; [2024]
    Nyckelord :Trähusbyggnad; konstruktionsbrand; utmaningar; räddningstjänsten; brandprojektering; trä; brandskydd; räddningsinsats; insats; wooden building; structural fire; challenges; the fire brigade; fire safety design; wood; fire protection; rescue operation; fire operation; fire risks; Technology and Engineering;

    Sammanfattning : The study explores the challenges of increased use of wood-frames in multi-story buildings in Sweden and its implications for fire safety. It investigates incident statistics and fire damages in wooden buildings, aiming to enhance the impact and safety of operations in these buildings. LÄS MER

  3. 3. Bränder i Elektrifierade Truckar

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Cecilia Östholm; [2024]
    Nyckelord :Litium-jon batteri bränder; Elektrifierade truckar; Förebyggande åtgärder; Åtgärder under brand; Litteraturstudie; Intervjustudie.; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to quantify the consequences of a fire in Kalmar Globals Heavy Electric Forklifts and Electric Reachstackers as well as what actions can be taken to reduce the effects of an ongoing fire and what preventing measures can be made by Kalmar Globals customers to create a safe environment and reduce the probability of a fire breaking out. This thesis builds on information gathered during a literature study and a complementary interview study. LÄS MER

  4. 4. 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. 5. Vedlevande skalbaggar 10–20 år efter brand i tallskog : en jämförelse mellan hällmark och produktiv mark

    Kandidat-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :KajsaLisa Olsson; [2024]
    Nyckelord :Tallimpediment; biologisk mångfald; vedlevande skalbaggar; naturvårdsbränning; Pinus sylvestris;

    Sammanfattning : The Swedish boreal forests have changed drastically in the last century. Intensive forestry with clear-cuttings and fire-prevention, cause a lack in dead wood diversity and volume. The current research on forests mainly focuses on productive forests and there is a knowledge gap regarding the importance of low-productive forest for biodiversity. LÄS MER
