  1. 1. Fire safety evaluation of multifunctional buildings - Special emphasis on antagonistic attacks and protection of sensitive areas

    Author : Martin Nilsson; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multifunctional building; multipurpose building; antagonism; terrorism; design fire; fire scenario; sensitive areas; electrical appliances room; fire protection; hypoxic air venting; reduced oxygen; fire growth; building code; fire safety engineering;

    Abstract : Multifunctional buildings, often hosting societal important functions, have become increasingly more common during the last years. The combination of many functions within the same building as well as an increased exposure to antagonistic attacks create new, not previously well analyzed problems for fire safety. READ MORE

  2. 2. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

    Author : Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

    Abstract : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. READ MORE

  3. 3. The Development of a European Fire Classification System for Building Products - Test Methods and Mathematical Modelling

    Author : Björn Sundström; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; Teknik; Technological sciences; Brandteknik; Fire Protection Engineering; Conflame; Cone Tools; FDS; CFD; Duhamel?s integral; Fire Growth Rate; FIGRA; Euroclass; SBI; Single Burning Item; Cone Calorimeter; Room Corner Test; fire modelling; Reaction to fire; flashover;

    Abstract : The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. READ MORE

  4. 4. Computational strategies in flame-spread modelling involving wooden surfaces

    Author : Jörgen Carlsson; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flamspridning; computational methods; pyrolysis modelling; fire modelling; fire growth; flame spread; Computational Fluid Dynamics; CFD; brandtillväxt; brandmodellering; pyrolysmodellering;

    Abstract : Various approaches to flame-spread and fire-growth modelling are discussed and are evaluated using experimental results from different tests. Use of Computational Fluid Dynamics, CFD, in fire modelling is discussed and the performance of different CFD codes in wall flow modelling is analysed. READ MORE

  5. 5. Experimental and Theoretical Study of Rack Storage Fires

    Author : Haukur Ingason; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Abstract : 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. READ MORE
