  1. 1. Validering av FDS för simulering av mindre vätgasläckage inomhus

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Emil Hamnes Alavei; Erik Andersson; [2023]
    Nyckelord :Hydrogen; Helium; Ventilation; CFD; FDS; Technology and Engineering;

    Sammanfattning : The prevailing global climate transition is incentivized to occur in a short period of time. Hydrogen is considered a pivotal element towards a renewable energy system. However, the physical and chemical properties of hydrogen give rise to the risk of fire and explosion. LÄS MER

  3. 2. Flow batteries - Impact on fire safety

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Ajay Menon; [2022]
    Nyckelord :Flow battery; Flow battery types; Flow battery risks; Firefighting; Fire risk analysis; Safety hazards in flow batteries; Fire risks in lithium-ion battery; Safety hazard in lithium-ion battery; Application of battery storage systems; Safety reports.; Technology and Engineering;

    Sammanfattning : The need for sustainable renewable energy has been increasing due to the negative impact of non-renewable energy sources. With the unstable and sporadic nature of sustainable renewable energy, flow batteries show immense potential in mitigating these issues. LÄS MER

  4. 3. Ventilering av brännbara gaser vid batteribränder

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

    Författare :Fredrik Gahm; [2021]
    Nyckelord :Lithium-ion batteries; thermal runaway; energy storage; battery storage; ventilation; explosion; explosion hazard.; Litiumjonbatterier; termisk rusning; energilager; batterilager; ventilation; explosion; explosionsrisk.;

    Sammanfattning : The use of lithium-ion batteries is something that is becoming more common in today’s society. They are found in a variety of electronic equipment such as mobile phones, laptops and tools. Several incidents have been reported due to lithium-ion batteries ending up in a state called thermal runaway. LÄS MER

  5. 4. Accurate Abundances of Giant Stars in the Local disk: A manual analysis of IR APOGEE spectra

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Ivalu Barlach Christensen; [2020]
    Nyckelord :Galactic Chemical Evolution; Astrophysics; Astronomy; IR Spectroscopy; Milky Way; Abundance; Physics and Astronomy;

    Sammanfattning : Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. LÄS MER

  7. 5. Exploring the application of neural networks in predictions of nuclear binding energies

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Waites; [2020]
    Nyckelord :neural networks; drip-line; nuclear physics; binding energy; exotic nuclei; Hartree-Fock-Bogolyubov; Physics and Astronomy;

    Sammanfattning : In this project the locations of the proton and neutron drip-lines are predicted using neural networks and theoretical data obtained by applying the HFBTHO program. For each of the neural networks a comparison is made between neural network predictions and experimental data in the region experimental data exists. LÄS MER
