  1. 6. Identification and characterization of design fires to be used in performance-based fire design of CERN facilities

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Darko Perovic; [2018]
    Nyckelord :Fire; Design fire; Vehicle fires; DMS 500; fast particulate analyser; Cone Calorimeter; Smoke characterization; Particle size distribution; Shell Diala; Midel; Cables; cable fires; Electrical cabinets; Electrical racks; CERN; Technology and Engineering;

    Sammanfattning : CERN operates the most complex particle accelerator facility built until today. As such, it consists of thousands of custom-made components spread both in upper ground facilities and in underground tunnels and caverns. LÄS MER

  3. 7. Determination of design fires for cables

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Sompoom Soontara; [2016]
    Nyckelord :FIPEC; FIPECMATCH; Similarity; Matching; Mismatching; Heat release rate curve and Comparison.; Technology and Engineering;

    Sammanfattning : FIPECMATCH is a cloud computing software for matching the new HRR small-scale cable test to the HRR small-scale cable test of FIPEC’s database. This package works by setting up two HRR filters, which would be able to select the most similar HRR pattern stored in the FIPEC’s database. LÄS MER

  4. 8. Combination of CFD and evacuation models for determination of FED and FEC levels

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Beom Jin Jeong; [2014]
    Nyckelord :evacuation; CFD; FED; FEC; FDS6; Technology and Engineering;

    Sammanfattning : Previously developed methods to evaluate FED and FEC level via combination of CFD and evacuation simulation have been verified by new features of FDS6 and extended to fire cases involving common building materials. The FED levels calculated by the conversion factor [1] based on carbon monoxide are compared with the direct calculation by way of mass fraction of carbon monoxide, hydrogen cyanide and carbon dioxide.

  5. 9. Brand i kabelschakt - Utvärdering av konsekvenser vid brand i kabelschakt vid SSAB

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Brandingenjörsprogrammet

    Författare :Fredrik Nilsson; [2014]
    Nyckelord :Kabelbrand; kabelschakt; SSAB; FIPEC; brandspridningsklass; FDS; Cable fire; Cable shaft; Flammability class; Technology and Engineering;

    Sammanfattning : This report evaluates the consequences of fire in a cable shaft at one of SSAB's facilities. Available models of cable fire behavior and the state of knowledge of cable fires in various configurations have been evaluated. Furthermore, an assessment has been made of which areas that is in need of more research. LÄS MER

  7. 10. Pyrotechnically Generated Aerosols ability to extinguish cable fires

    Kandidat-uppsats, Lunds universitet/Brandingenjörsprogrammet; Lunds universitet/Avdelningen för Brandteknik

    Författare :Marco De Pedis; Oskar Jonsson; [2013]
    Nyckelord :PGA; Pyrotechnically Generated Aerosols; suppression; electrical fire; cable fire; high risk facilities; decision tool; Technology and Engineering;

    Sammanfattning : This study aimed to evaluate the use of Pyrotechnically Generated Aerosols in electrical fires. To represent a common starting point for these fires, a cable fire ignited by a shortcut was chosen. In order to do this in a realistic way, a new method with heating the cables from the inside was used. LÄS MER
