  1. 21. Experimental and Theoretical Study of Rack Storage Fires

    Författare :Haukur Ingason; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; response time; in-rack sprinkler; flame heat transfer; gas velocity; gas temperature; flame height; in-rack fire plume; Rack storage fire; fire growth rate; Technological sciences; Teknik;

    Sammanfattning : A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. LÄS MER

  4. 23. Methodology for Assessing Learning from Incidents - a Process Industry Perspective

    Författare :Anders Jacobsson; Avdelningen för Brandteknik; []
    Nyckelord :Accidents; Incidents; Learning from incidents; Learning cycle; Lesson learned; Process industry;

    Sammanfattning : Learning from incidents (from minor disturbances to major accidents) is considered one of the most important ways in the process industry to learn from experiences for improving safety performance. Most companies have a formal incident learning system and considerable resources are used for reporting incidents and for utilising these experiences to prevent future incidents. LÄS MER

  5. 24. Fire Dynamics in Multi-Room Compartment Fires

    Författare :Nils Johansson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire safety engineering; fire dynamics; multi-room compartment; numerical experiment; small-scale experiment; hot-gas-layer temperature; hot-gas-layer interface height; reproducibility;

    Sammanfattning : Fire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. LÄS MER

  7. 25. Numerical experiments - a research method in fire science

    Författare :Nils Johansson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental uncertainty; accuracy; fire dynamics; compartment fires; models; experiments; Numerical experiments;

    Sammanfattning : Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. But, there are shortcomings and difficulties with conducting these traditional fire experiments. LÄS MER
