  1. 1. Spread of smoke and fire gases via the ventilation system

    Detta är en avhandling från Division of Building Science, Lund University

    Författare :Polina Gordonova; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compartment fires; fire flow; fire pressure; fire simulation; smoke spread; ventilation ducts; brandteknik; brand; brandspridning; rökspridning; ventilation; ventilationskanaler; beräkningsmodeller; datorprogram; simulering; teori;

    Sammanfattning : This thesis examines the problem of smoke spread via ventilation ducts to adjacent room(s) in case of a compartment fire. The main goal is to examine the possibility of operating the fans during different fires in four types of buildings (compartments, hospitals, offices and hotels) and to estimate the risk of smoke spread in different conditions..

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

    Detta är en avhandling från Fire Safety Engineering and Systems Safety

    Författare :Björn Sundström; [2007]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. An Engineering Approach to Fire Fighting Tactics

    Detta är en avhandling från Brandteknik

    Författare :Stefan Särdqvist; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; risk management; decision making; fire brigade; fire-fighting tactics; pre-fire planning; fire safety engineering;

    Sammanfattning : This report presents a quantified model as a guide for the Incident Commander to determine the most suitable fire-fighting tactics in advance for given conditions at specific objects. The model is applied to two chemical warehouses. LÄS MER

  4. 4. Determination of Material Properties for Fire Modelling

    Detta är en avhandling från Avdelningen för Brandteknik, Lunds Tekniska Högskola

    Författare :Ulf Göransson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material properties; Material degradation; Measurements; Fire test data; Byggnadsteknik; Building construction; Teknik; Technological sciences; Fire; Surface temperature; Mathematical modelling;

    Sammanfattning : Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. LÄS MER

  5. 5. Exit choice in fire emergencies - Influencing choice of exit with flashing lights

    Detta är en avhandling från Brandteknik och riskhantering, LTH, Lunds Universiet, Box 118, 22100 Lund

    Författare :Daniel Nilsson; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Theory of Affordances.; green flashing lights; active evacuation systems; affiliation; exit choice; evacuation; egress; Fire;

    Sammanfattning : Fire accidents and evacuation experiments have revealed that people often use familiar exits in fire emergencies. However, the design of emergency exits has also been shown to impact people’s choice of exit. LÄS MER
