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

   University essay from Lunds universitet/Avdelningen för Brandteknik

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

   Abstract : 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. Visibility in Smoke With Different Extinction Coefficients

   University essay from Lunds universitet/Avdelningen för Brandteknik

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

   Abstract : 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.

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

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Hugo Zacharoff; [2021]
   Keywords : Cable fires; FDS; cone calorimeter;

   Abstract : 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.

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

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : David Bergendorff; Jonas Lundin; [2021]
   Keywords : ;

   Abstract : 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. READ MORE

6. 5. A COMPARATIVE STUDY OF TRAVELLING FIRE IN LARGE SPACES WITH MULTI-ZONE FIRE MODEL AND FDS

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Paolo Bertoli; [2021]
   Keywords : Multi-Zone fire model; FDS; Large enclosures; Travelling fire.; Technology and Engineering;

   Abstract : A knowledge of far field temperatures is valuable for Performance Based Design structural analysis and life safety analysis, where a parametric study is needed. A fire model using multiple zones called a multi zone (MZ) fire model has in previous studies shown good potential as an analytical tool for predicting far field temperatures in large compartments.
