  1. 1. A Comparison Between FDS and the Multi-Zone Fire Model Regarding Gas Temperature and Visibility in Enclosure Fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Benjamin Waldeck; [2020]
    Keywords : Enclosure fire; FDS; Multi-Zone Fire Model; gas temperature; Visibility; Technology and Engineering;

    Abstract : When designing large buildings with complex geometry there is often a need for performance-based design and the use of computer models. CFD models like FDS that are available and validated for this purpose are typically time consuming and require large amounts of computing power. READ MORE

  2. 2. The verification and validation of a probabilistic risk analysis method for road tunnels

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Kim Genberg; Karin Sandin; [2020]
    Keywords : Tunnels; fire; evacuation; probabilistic risk analysis; QRA; verification and validation; Technology and Engineering;

    Abstract : In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled.

  3. 3. Comparing a full scale test with FDS, FireFOAM, McCaffrey & Eurocode

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Erik Edin; Mattias Ström; [2019]
    Keywords : FDS; FireFOAM; OpenFOAM; Performance-Based Design; Localized fire.;

    Abstract : In the rapidly growing field of CFD-calculations (Computational Fluid Dynamics), companies and organizations are bringing forth new tools, tools that display an image of a given fire scenario. These tools are developed because they provide time efficiency as well as a sustainable economic approach. READ MORE

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

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Yalong Wu; [2019]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Alexander Johansson; [2019]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE
