  1. 1. C³Fire : a microworld supporting emergency management training

    Författare :Rego Granlund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The objective of this work has been to study how to support emergency management training using computer simulations. The work has focused on team decision making and the training of situation assessment in a tactical reasoning process. LÄS MER

  3. 2. Simulation of Combustion and Fire-Induced Flows in Enclosures

    Författare :Heimo Tuovinen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cumbustion; Chemical kinetics; Flamelet model; CFD models; Fire-induced flows;

    Sammanfattning : Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. LÄS MER

  4. 3. Uncertainty and Risk Analysis in Fire Safety Engineering

    Författare :Håkan Frantzich; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event tree; fire engineering design; reliability index; FOSM; Monte Carlo simulation; Risk analysis; uncertainty analysis; response surface.; Technological sciences; Teknik;

    Sammanfattning : Two Quantitative Risk Analysis (QRA) methods are presented which can be used to quantify the risk to occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. LÄS MER

  5. 4. Models for coupled active-passive population dynamics : Mathematical analysis and simulation

    Författare :Thi Kim Thoa Thieu; Adrian Muntean; Matteo Colangeli; Grigorios A. Pavliotis; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pedestrian dynamics; simple exclusion process; Forchheimer flows; Skorohod equations; nonlinear coupling; heterogenous domain; homogenization; drafting; evacuation; Matematik; Mathematics;

    Sammanfattning : In this dissertation, we study models for coupled active--passive pedestrian dynamics from mathematical analysis and simulation perspectives. The general aim is to contribute to a better understanding of complex pedestrian flows. LÄS MER

  7. 5. 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
