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

   Författare :Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

   Sammanfattning : 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. LÄS MER

3. 2. Demand for Extinguishing Media in Manual Fire Fighting

   Författare :Stefan Särdqvist; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire fighting; Fire brigade; fire suppression; extinguishing agents; extinction; Technological sciences; Teknik;

   Sammanfattning : Risk analysis and intervention planning are important in fire prevention and risk management strategies. This study has shown that it is possible to use fire safety engineering models to estimate the development of fires on a realistic scale, and the corresponding requirement for extinguishing media.

4. 3. Experimental measurements of water mist systems and implications for modelling in CFD

   Författare :Bjarne Husted; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; fire suppression; CFD; FDS; fire safety engineering; PDA; water mist; PIV;

   Sammanfattning : The use of water mist for fire extinguishment has increased rapidly in recent years. The main reason is the abandonment of halon-based extinguishing systems in favour of environmentally friendlier systems. Furthermore the use of water mist systems has spread from mainly marine applications to also include the protection of buildings. LÄS MER

5. 4. 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

7. 5. Utilizing Research to Enhance Fire Service Knowledge

   Författare :Stephen Kerber; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire dynamics; fire service; fire safety engineering; firefighting; firefighter safety;

   Sammanfattning : This thesis explores the fire service workplace through full-scale experiments. Evidence-based information has been developed to be combined with firefighter experience to improve their knowledge of fire dynamics and the cause and effect impact of their tactics on life safety, property conservation, and incident stabilization.
