  1. 1. Sprinklers påverkan på ventilationsbrandskydd : En funktionsanalys avseesnde sprinklers påverkan på brandgasspridning i hotellmiljö.

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

    Författare :Erik Rönnberg; Elias Björnqvist; [2020]
    Nyckelord :Sprinkler; brandgasspridning; hotell; brandskydd; FDS; PFS;

    Sammanfattning : The fact that a building is covered by a well-arranged fire protection is today a basic precondition for the safety of a building. Good and organized fire protection is also an essential part of a good safety culture. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

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

    Sammanfattning : 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.

  4. 4. The Influence of Cavity Widths and Lateral Ventilation Conditions on the Fire Behaviour within a Non-Combustible Ventilated Façade System

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Daniel Fogerty; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Present uncertainties in key ventilation parameters, characterising the fire performance of facades, has necessitated clarification in the foundational understanding of the Fire Science Body of Knowledge. A test program conducted in collaboration between Lunds Universitet and the Kingspan Group, studied the influence of cavity widths and lateral ventilation conditions on the fire behaviour within Intermediate-scale ventilated façades following the ISO 13785-1 standards.
