  1. 1. A COMPARATIVE STUDY OF TRAVELLING FIRE IN LARGE SPACES WITH MULTI-ZONE FIRE MODEL AND FDS

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Paolo Bertoli; [2021]
    Nyckelord :Multi-Zone fire model; FDS; Large enclosures; Travelling fire.; Technology and Engineering;

    Sammanfattning : A knowledge of far field temperatures is valuable for Performance Based Design structural analysis and life safety analysis, where a parametric study is needed. A fire model using multiple zones called a multi zone (MZ) fire model has in previous studies shown good potential as an analytical tool for predicting far field temperatures in large compartments.

  3. 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.

  4. 3. En jämförelse mellan standardbrandkurvan och den teoretiska temperaturutvecklingen vid lägenhetsbränder

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

    Författare :Jesper Uddmyr; [2020]
    Nyckelord :The standard fire curve; parametric fire; compartment fires; the Eurocode model; Standardbrandkurvan; parametrisk brand; lägenhetsbränder; Eurokodmodellen;

    Sammanfattning : När byggnadsdelars brandmotstånd provas och klassificeras används nästan enbart standardbrandkurvan som definierad temperaturexponering över tid. Brandexponeringen beskrivs i den europeiska standarden EN 1363-1 samt den internationella standarden ISO 834. LÄS MER

  5. 4. Factors influencing the generation of carbon monoxide in fires partially suppressed through water mist application

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Haydn Lewis; [2020]
    Nyckelord :Fire safety engineering; water mist; fire suppression; carbon monoxide; water; combustion; Technology and Engineering;

    Sammanfattning : Fires in the built environment typically consist of diffusion flames with inefficient mixing of fuel and oxygen, resulting in a degree of incomplete combustion and the generation of carbon monoxide. Fire suppression systems, used to control the growth and spread of fire, influence the combustion reaction process. LÄS MER

  7. 5. Studies on the application of gas cooling as used by firefighters

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jan Bonnier; [2017]
    Nyckelord :Gas cooling; Firefighting; Fire Service; 3D-technique; Technology and Engineering;

    Sammanfattning : Gas cooling is a technique used by firefighters to create a safer work environment inside a compartment fire. By spraying water into the smoke layer, the smoke layer temperature will decrease significantly. Next to the lower temperature, the flammability of the smoke layer will also decrease. LÄS MER
