1. 1. Utvärdering av tunnelbrandsmodeller

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Johanna Gondinger; Alva Larsson; [2024]
   Nyckelord :Tunnelbränder; FDS; handberäkning; branddynamik; brandexperiment Tunnel fires; CFD; hand calculations; fire dynamics; fire experiment; Technology and Engineering;

   Sammanfattning : The purpose of this study was to investigate the predictive capabilities of hand-calculation methods and simulations using FDS in understanding the behavior of a tunnel fire in terms of temperature and incident radiation. Additionally, the study aimed to examine the repeatability of a large-scale fire experiment. LÄS MER

3. 2. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries

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

   Författare :Elin Bergroth; Greta Torstensson; [2023]
   Nyckelord :Solar Photovoltaic; National Guidelines; Fire Department; FE-analysis; TASEF; Solceller; Nationella Riktlinjer; Räddningstjänst; FE-analys; TASEF;

   Sammanfattning : The global use of energy increases every day and to meet the growing demand, energy sources are constantly being developed to become more efficient and reliable. During the last decade, the global solar photovoltaics (PV) capacity has increased every year and in 2017, solar PV was the global leading power source of renewable energy. LÄS MER

4. 3. Investigation on Enhancing Fire Threat Perception in Virtual Reality through Subject-Expectancy Effect

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Hsuan-Ting Liu; [2023]
   Nyckelord :Virtual reality; safe distance; subject-expectancy effect; thermal radiation; placebo effect; fire scenario.; Technology and Engineering;

   Sammanfattning : This thesis examines the use of subject-expectancy effect on enhancing fire threat perception in virtual reality. The study involves a virtual fire scenario design and 33 participants who experience virtual fires of three different scales in the scenario using a head-mounted display as visual and auditory perception and adopting physical movement in real world as their way of locomotion.

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. Testing macroscopic traffic evacuation models for wildland-urban interface fires

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Adam Ardinge; [2021]
   Nyckelord :WUI-NITY; WUI; V V; traffic evacuation; WUI fire evacuation; simulation model; verification testing; validation testing; Kincade; Technology and Engineering;

   Sammanfattning : This thesis presents the verification and validation testing performed on the evacuation simulation platform WUI-NITY which has the aim of being a simulation tool for the integration of different layers, such as pedestrian, traffic and wildfire with evolving dynamic interactions. The present thesis aims at applying a set of verification tests and validation testing suitable for WUI-NITY with a focus on the traffic component. LÄS MER
