  1. 1. 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

  3. 2. 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

  4. 3. Evaluation and Mitigation of Industrial Fire Hazards

    Författare :Petra Andersson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Effect of fires; Accidental release; Water mist; Halon replacement; Industrial Fire Hazards; Human burns; Smoke detektion;

    Sammanfattning : A tool suitable for conducting industrial fire and explosion hazard analysis is presented, together with an identification of weak links in the hazard evaluation chain. For some of the weak links additional research has been carried out. LÄS MER

  5. 4. Strong Light-Matter Coupling: the Road from Conventional to Cavity-Free Polaritons

    Författare :Adriana Canales Ramos; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fabry-Pérot microcavities; self-hybridized polaritons; Mie modes; Strong and ultrastrong coupling; Lorentz resonances; decay rates; cavity-free polaritons; Casimir force; 2D–crystals; plasmons; water droplets.; self-assembled microcavities;

    Sammanfattning : The interaction between light and matter is fundamental in perceiving and understanding the world. The interaction is typically weak, meaning light only perturbs matter without changing its properties. LÄS MER

  7. 5. Studies on Airway Surface Liquid in Connection with Cystic Fibrosis

    Författare :Inna Kozlova; Godfried Roomans; Anca Dragomir; Marieann Högman; Isabelle Sermet-Gaudelus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cystic fibrosis; CFTR; airway surface liquid; ion content; anesthesia; mist tent therapy; Pseudomonas aeruginosa infection; Cell biology; Cellbiologi;

    Sammanfattning : Cystic fibrosis (CF) is one of the most common fatal inherited diseases, most prevalent among Caucasians. CF is caused by a mutation in the gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR), which helps to create sweat, digestive juices, and airway surface liquid (ASL).
