  1. 1. Analys av brandspridning inom probabilistiska säkerhetsanalyser använda i kärnkraftsindustrin

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Fredrik Wennberg; Elias Karlsson; [2019]
    Nyckelord :Brandspridning PSA; brandspridning kärnkraft; brandspridning screening; screeningkriterium brand; fire spread PSA; fire spread nuclear facility; fire spread screening; screening criteria fire; Technology and Engineering;

    Sammanfattning : The work presented in this report was based upon two different stages, with the aim of coming up with an improved screening process concerning fire spread within PSA at Ringhals Nuclear Power Plant in Sweden. The first phase consisted of creating a methodology for the screening process, which was based on various screening data, such as CDF, fire loads and openings between compartments. LÄS MER

  2. 2. Testing the International Standards Organization Verification and Validation protocol for evacuation simulations-An application to the FDS+Evac model

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Yalong Wu; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Nowadays, many evacuation models exist in the market, and new models are continuously released with new features. How to assess the usability and reliability of model results becomes an issue for both developers and users. Therefore, verification and validation (V&V) protocols were introduced in the assessment process of evacuation models. LÄS MER

  3. 3. A Modelling Study on the Impact of Luggage and Airworthiness Certification on Aircraft Evacuation

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Alexander Johansson; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Real-life aircraft evacuation drills can cost up to 2 million USD and may not at the same time be able to represent a real emergency scenario. with the use of evacuation models as a complement to the testing may reduce this cost. LÄS MER

  4. 4. Analytisk dimensionering av brandsektioner

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Johannes Priebe; [2019]
    Nyckelord :Brandsektion; byggregler; brandvägg;

    Sammanfattning : Enligt Boverkets Byggregler 26 (BBR) kapitel 5:56 ska stora byggnader utformas så att omfattande brandspridning inom byggnaden begränsas. Det tillhörande allmänna rådet säger att detta bör uppfyllas genom att utforma byggnader med brandceller, brandsektioner, brandtekniska installationer eller en kombination av dessa. LÄS MER

  5. 5. Evaluation of Strategies for the Integration of Building Information Modelling (BIM) with Simulation of Fires in Enclosures

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Silvia Parra Diettes; [2019]
    Nyckelord :Building Information Modelling; Simulation of Fires; Computational Fluid Dynamics; Fire Dynamics Simulator; Thermal properties; Industry Foundation Classes; Technology and Engineering;

    Sammanfattning : Computational Fluid Dynamics (CFD) is the study of fluid flows for the analysis of phenomena by scenarios simulated in a computer-based environment. One of the most well-known CFD simulation packages in the fire safety field is Fire Dynamic Simulator (FDS). LÄS MER
