  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. 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. 3. Beständigheten hos brandimpregnerat trä

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Filip Engström; Hannes Psajd; [2024]
    Nyckelord :Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

    Sammanfattning : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

  5. 4. Energiförluster från vs-rör med intilliggande balkong : Parameterstudie i Comsol Multiphysics

    Master-uppsats, Karlstads universitet

    Författare :Adam Åberg; [2023]
    Nyckelord :vs-rör; energiförluster; balkong; egcobox; flebostadshus;

    Sammanfattning : Energy issues are today in high priority nationally and internationally as its impact on the environment and climate has become increasingly apparent. The real estate sector accounts for 34 % of Sweden's total energy consumption, where 70 % goes to heating apartment buildings. LÄS MER

  7. 5. Simulering av vattenburen golvvärme med finita elementmetoden : värmeavgivning vid olika mönster för rörläggning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Byggteknik och byggd miljö

    Författare :Joakim Nyberg; [2023]
    Nyckelord :comsol; finite element method; multiphysics; multiphysics simulation; PDE; DE; FEM; 4GDH; governing equations; simulering; comsol; vattenburen golvvärme; golvvärme; FEM; finita elementmetoden; PDE; partiella differentialekvationer; fjärde generationens fjärrvärme; 4GFV; EAS; värmesimulering;

    Sammanfattning : This report formulates the boundary conditions and discretization method for conducting a simulation of heat with liquids and solids through the finite element method. It introduces the reader to the movement that is due today with optimization of heat transport and mitigation generally described as the fourth generation of district heating. LÄS MER
