  2. 1. Design fires in underground hard rock mines

    Author : Rickard Hansen; Haukur Ingason; Håkan Frantzich; Mälardalens högskola; []
    Keywords : Design fire; underground; hard rock mine; vehicle fire; smoke spread; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : During several decades considerable research activities have been conducted with respect to fires in coal mines, but the research activities with respect to hard rock mines have been limited. As the hard rock mines are getting more complex the need for deeper understanding of fires in underground hard rock mines are getting more in demand. READ MORE

  4. 2. Determination and control of some pollutants in indoor environments

    Author : Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; indoor pollutants; dampness; purification; tobacco smoke;

    Abstract : Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. READ MORE

  5. 3. On the Characteristics of Fires in Tunnels

    Author : Anders Lönnermark; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experiments; tunnel fire; heat release rate; temperature; fire spread; ventilation; backlayering; pulsations; thermoacoustic instability; equivalence ratio; emissions; gas concentrations; toxicity; Technological sciences; Teknik; Building construction; Byggnadsteknik; Road transport technology; Vägtransportteknik; Railway transport technology; Järnvägstransportteknik;

    Abstract : Important phenomena related to tunnel fires are presented including both experimental and theoretical work. The main focus is on the large-scale fire tests performed in 2003, in the Runehamar tunnel in Norway. READ MORE

  6. 4. Low smoke halogen-free materials for wire and cable applications

    Author : Anna Lundgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame retardant; calcium carbonate; calcium silicate; Casico; polyolefin; effervescence; intumescent structure; thermal degradation; silicone elastomer;

    Abstract : Fire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start a fire and/or spread one. Traditionally, materials containing halogen have been used as primary insulation in low voltage power and telecommunication cables and most cables used today therefore contain halogen. READ MORE

  7. 5. The rotating injector as a tool for exploring DI diesel combustion and emissions formation processes

    Author : Magnus Sjöberg; KTH; []
    Keywords : diesel spray combusion; rotating injector. Air swirl; air fuel-mixing. Soot. NO. CO; flame visualization. Chemking modeling. Soot deposition;

    Abstract : A diesel fuel injector has been modified to allow rotationaround its axis, driven by an electric motor. Injections at upto 6000 rpm from the rotating injector have been investigatedunder the influence of air swirl on one optical research engineand one optically accessible heavy-duty diesel engine.
