  1. 1. Exploring the Feasibility of Using Fire Dynamics Simulator to Improve the Calculation of the Wildfire Available Safe Egress Time

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Alfred El Haddad; [2023]
    Nyckelord :Wildfire; Trigger buffer; WUI; WASET; FDS; QGIS; Level set; WUI evacuation.; Technology and Engineering;

    Sammanfattning : Wildland-Urban Interface (WUI) fires pose a significant threat to public safety and property in areas where urban development encroaches upon natural landscapes. This thesis aims to investigate the effect of smoke from a WUI fire on the tenability conditions of a small village and to establish a worst-case-scenario trigger boundary around it as an improved basis for the WUI available safe egress time (WASET).

  3. 2. Finite Element Simulation of Moisture Transport in Cellulose Insulation Material of Power Transformers

    Master-uppsats, Uppsala universitet/Tillämpad mekanik

    Författare :Luc Villibord; [2023]
    Nyckelord :;

    Sammanfattning : Power Transformers are an important and complex part of the electrical transmission technology. One of the main producers of these transformers worldwide is Hitachi Energy, for which this work has been done. LÄS MER

  4. 3. Fönsterutrymning – en experimentell studie av personflöde och säkerhetsmässiga aspekter vid utrymning via fönster

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Christoffer Rosenqvist Bergenzaun; Kasper Holmberg; [2022]
    Nyckelord :Utrymning; fönster; fönsterutrymning; flöde; personflöde; säkerhet; trygghet; window; evacuation; flow; security; safety; Technology and Engineering;

    Sammanfattning : Evacuation flow through connections such as doorways and staircases is a subject that has been studied and documented for decades. Evacuation flow through windows however is a subject that has been studied to a much lesser extent. LÄS MER

  5. 4. Modellering av utrymningshissar som utrymningsväg från djupa undermarksanläggningar

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Oscar Mårtensson; Anna-Lena Johansson; [2022]
    Nyckelord :Evacuation; egress; elevator; underground; building; evacuation elevator; emergency elevator; ascending evacuation; stairs; model; occupant evacuation elevator; OEE; exit choice; human behaviour; Technology and Engineering;

    Sammanfattning : Elevators could be an important alternative means of egress when it comes to evacuation. This report is the result of a model developed to calculate the efficiency of elevator evacuation in different scenarios in deep underground facilities. LÄS MER

  7. 5. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Lorenzo Contini; [2022]
    Nyckelord :Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

    Sammanfattning : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. LÄS MER
