  1. 6. Släcksystem för ubåtar - vattendimma

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Axel Nordström; Simon Thorvaldsson; [2023]
    Nyckelord :Ubåt; vattendimma; krav och regelverk; brandsäkerhet; brandskyddssystem; Submarine; water mist; rules and regulations; fire safety; fire suppression system; Technology and Engineering;

    Sammanfattning : This report is written on the behalf of SAAB Kockums AB to investigate the feasibility of using water mist fire protection systems on board conventional submarines as an alternative to the traditional solution using Halon 1301. Halon 1301 has since the late eighties been phased out due to environmental concerns. LÄS MER

  3. 7. Exploring the Feasibility of Using Fire Dynamics Simulator to Improve the Calculation of the Wildfire Available Safe Egress Time

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Alfred El Haddad; [2023]
    Nyckelord :Wildfire; Trigger buffer; WUI; WASET; FDS; QGIS; Level set; WUI evacuation.; Technology and Engineering;

    Sammanfattning : Wildland-Urban Interface (WUI) fires pose a significant threat to public safety and property in areas where urban development encroaches upon natural landscapes. This thesis aims to investigate the effect of smoke from a WUI fire on the tenability conditions of a small village and to establish a worst-case-scenario trigger boundary around it as an improved basis for the WUI available safe egress time (WASET).

  4. 8. Suppression of Li-ion Battery Fires

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Linfan Cai; [2023]
    Nyckelord :Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

    Sammanfattning : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

  5. 9. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Hannah Sophie Jakob; [2023]
    Nyckelord :coarse woody debris; conservation; biodiversity; boreal forest; Daldinia loculata; Fennoscandia; prescribed burning; regeneration; wildfire; woodpecker;

    Sammanfattning : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. LÄS MER

  7. 10. Wholesale market + - a transformation of the wholesale market Munich in a water sensible mixed district

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Annika Enzinger; [2023]
    Nyckelord :mixed use; water sensible; sustainable; transformation; Arts and Architecture;

    Sammanfattning : There is always talk of climate change in the future, but climate change is already present in all its facets. Intense droughts, water scarcity, severe fires, rising sea levels, floods, melting polar ice, catastrophic storms, and the decline of biodiversity are already visible. LÄS MER
