  2. 2. 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

  3. 3. Thermal Exposure Caused by the Smoke Gas Layer in Pre-flashover Fires : A Two-zone Model Approach

    M1-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Lucas Andersson; [2016]
    Nyckelord :Thermal exposure; smoke gas layer; two-zone model;

    Sammanfattning : A pre-flashover fire is very different from a post-flashover fire. The main difference is that in a pre-flashover fire the gas temperature and the radiation temperature differ. One thing that makes it a lot different is that the thermal exposure induced by a pre-flashover fire is largely affected by the smoke gas layer. LÄS MER
