  1. 6. A multi-scale approach for predicting the fire response of building barriers

    Författare :Blanca Andrés Valiente; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; Building Barriers; Heat transfer; Experimental; Gypsum; Stone wool; furnace; H-TRIS;

    Sammanfattning : Building barriers are compartmentation elements in buildings that limit the passage of fire and smoke to adjacent spaces. They are key elements in the overall response of a building in a fire. The adequate fire response of building barriers is usually assessed by the fulfilment of standardized resistance to fire tests.

  3. 7. Application of Virtual Reality in the study of Human Behavior in Fire : Pursuing realistic behavior in evacuation experiments

    Författare :Silvia Arias; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual Reality; behavioral realism; fire evacuation; VR experiments;

    Sammanfattning : Virtual Reality (VR) experiments are used to study human behavior in fire because they allow simulation of fire events with relatively low risks to the participants, while maintaining high levels of experimental control. Manystudies have used VR experiments to explore aspects of the human response to fire threats, but VR experiments as a research method are yet to be subjected to a systematic process of validation.

  4. 8. Water mist fire protection systems : The development of testing procedures for marine and heritage applications

    Författare :Magnus Arvidsson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattendimma; brand; fartyg; kulturbyggnader; Water mist; fire protection; fire test procedures; Ships; marine applications; heritage buildings;

    Sammanfattning : Modern, commercial water mist fire protection system technology evolved at the beginning of the 1990s due a need to replace halon fire-extinguishing systems and improve fire safety on passenger ships. This thesis documents the unknown water mist system development work by two Swedish companies during the 1970s and 1980s. LÄS MER

  5. 9. Övertändning, backdraft och brandgasexplosion sett ur räddningstjänstens perspektiv

    Författare :Lars-Göran Bengtsson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; warning signs; smoke gas explosion; flashover; backdraft;

    Sammanfattning : This report presents a detailed description of the phenomena flashover, backdraft and smoke gas explosion. The physical and chemical processes which are involved in these phenomena are thoroughly discussed. The report also describes a number of compartment fire scenarios which are believed to be the most common scenarios occurring in Sweden. LÄS MER

  7. 10. Fire behaviour of selected polymeric materials : Numerical modelling and validation using microscale and bench scale test methods

    Författare :Abhishek Bhargava; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAEM; pyrolysis modelling; Polymer flammability; mass loss rate; Heat release rate HRR ;

    Sammanfattning : The ability to predict fire behaviour of materials is of key interest to building materials industry. Themain reason for it is expensive fire testing and certification costs borne by the manufacturers to bring a finished product to market. LÄS MER
