  1. 16. INTERMEDIATE-SCALE TESTS AND CONE CALORIMETER TESTS - FIRE BEHAVIOUR OF SELECTED FACADE MATERIALS

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tanja Cernosa; [2020]
    Nyckelord :Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

    Sammanfattning : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.

  3. 17. How explosive should the launch of the new Samsung Galaxy Note8 be?

    L3-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Tuva Brännström; Lara Kristina Siebert; [2020]
    Nyckelord :brand management; crisis management; reputation; corporate brands; case study; Samsung; Business and Economics;

    Sammanfattning : In August 2016, Samsung launched the Galaxy Note7, but the initial excitement of both the company and the market dropped painfully after only a few days when reports covered phones that were bursting into flames. With an increasing number of incidents and massive media coverage, Samsung had to quickly step up its actions from a reluctant withdraw to a global recall within only one month. LÄS MER

  4. 18. 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

  5. 19. Fundamental combustion properties of alternative fuels for energy transition

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Yijing Mao; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Validation and improvement of chemical kinetic modelling require accurate experimental data. The over goal of the present work is to obtain accurate data by using techniques that have been previously implemented in common flames, e.g. LÄS MER

  7. 20. Simulation Study on Lifted Hydrogen and Methane Jet Flames in Hot Vitiated Coflow

    H-uppsats,

    Författare :Henrik Forsting; [2019-07-03]
    Nyckelord :Farkostteknik; Hållbar utveckling; Energiteknik; Energi; Vehicle Engineering; Sustainable Development; Energy Engineering; Energy;

    Sammanfattning : Combustion of fossil fuels is the most important energy source today. Burning fossil fuel is however expensive and bad for the enviroment. Improving the combustion technology to reduce fuel consumption, and to be able to burn renewable fuels is therefore of great importance. LÄS MER
