  1. 1. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Annachiara Nardone; [2023]
    Nyckelord :tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

    Sammanfattning : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. LÄS MER

  2. 2. A Comparison between the Wickström Compartment Fire Model with Experiments and other Calculation Methods

    M1-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Anna Pettersson; Carolina Puga Staffan; [2021]
    Nyckelord :;

    Sammanfattning : An Excel spreadsheet application has been developed for calculating pre-flashover compartment fire temperature according to the method described in the book ”Temperature Calculation in Fire Safety Engineering” written by Wickström 2016. Here called the Wickström Compartment Fire Model, WCFM, which is a model where the surrounding structure can be assumed either as lumped heat or as semi-infinite.

  3. 3. 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

  4. 4. Influence of ventilation on ro-ro space fire development : A study using two-zone fire models in order to explore tendencies of how different ventilation parameters affects the fire development in a ro-ro space

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

    Författare :Martin Lindgren; Andreas Lilja; [2019]
    Nyckelord :Fire; Ro-ro space; Ventilation; Simulation; Two-zone model; Brand; Rorolastutrymme; Ventilation; Simulering; Tvåzonsmodell;

    Sammanfattning : A ship to which vehicles and other loads can be rolled on and off is usually named ro-ro ship. A ro-ro ship consists of large corridor shaped space, normally extending to a considerable length or the entire length of the ship, which is usually loaded with various vehicles or stowage units.

  5. 5. Planlösning i bostäder som en del av det passiva brandskyddet

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Andreas Stagnebo; Axel Philip; [2017]
    Nyckelord :Floor plans; fire protection; CFD; FDS; CFAST; case study methodology; hand calculation methods; fire statistics; residential dwellings; planlösning; brandskydd; fallstudie; handberäkningsmetoder; brandstatistik; bostäder; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to investigate the impact of floor plan parameters in a residential dwelling regarding the consequences of fire that may endanger human life and health. The thesis follows a case study methodology and investigates isolated parameters in floor plans using CFD and CFAST modelling. LÄS MER
