  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. Bilbränder i slutna parkeringsgarage : Personbilar från olika tidsåldrar och dess påverkan vid implementering av brandgasvetnitilation

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jesper Gylling; Victor Pettersson; [2022]
    Nyckelord :Brandgasventilation; Parkeringsgarage;

    Sammanfattning : Dagens krav för brandgasventilering av källare, och i förlängningeneller slutna garage, är en kvarleva av krav som sattes under 1970-talet. Sedan 70-talet har biltillverkningen utvecklats och dagens bilmodeller är uppbyggda annorlunda än dåtidens bilar. LÄS MER

  4. 3. Visibility in Smoke With Different Extinction Coefficients

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Lea Elhokayem; [2022]
    Nyckelord :Visibility; smoke; exit sign; extinction coefficient; visibility constant; evacuation; Technology and Engineering;

    Sammanfattning : Visibility in smoke has since the 1970s gained some attention, mostly after Tadahisa Jin ran the experiments which helped him develop todays widely used visibility equation. By showing that visibility can be assumed to be inversely proportional to the extinction coefficient by a visibility constant (equal to 8 for light emitting sign and 3 for light reflecting), Jin opened up new doors for researchers who were testing out his theory by going around experimenting in different ways and also by showing that there is way for more research to be done.

  5. 4. Simulating cable fires in Fire Dynamics Simulator : Based on small scale testing in cone calorimeter

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Hugo Zacharoff; [2021]
    Nyckelord :Cable fires; FDS; cone calorimeter;

    Sammanfattning : In a society increasingly more influenced by technology and electricity, electrical and computer cables will play a more vital role in humans’ everyday life. With an increasing number of cables being introduced into society, the risk of fires caused by or involving cables will increase and become a more common danger to property and human lives. LÄS MER

  7. 5. Simulation of standing versus crawling during evacuation from a smoke-filled room

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Bergendorff; Jonas Lundin; [2021]
    Nyckelord :;

    Sammanfattning : Crawling is often the recommended method when evacuating from a burning room. In this study, an agent based crowd simulation in combination with a fire dynamics simulator is used in order to compare how well crawling evacuation compares to a standing type of evacuation. LÄS MER
