“…Yangın dinamiği simülasyonu (FDS), yangından çıkan duman ve sıcak gazların akışını modelleyen hesaplamalı akışkan dinamiği (CFD) modelidir [15]. PyroSim, NIST tarafından geliştirilen Yangın Dinamik Simülasyonu (FDS)'nin grafiksel ara yüzüdür [16]. PyroSim, FDS simülasyonları için girdilerin hazırlanmasını kolaylaştırmak, yangın modelleri oluşturmak ve analizini yapmak amacıyla geliştirilmiştir [17].…”

 Fire dynamics simulation in the domed mosque  The effect of the dome drum windows (i.e. open or closed) on fire safety  Examination of the available safe egress time (ASET) of domed mosque design Name of Floor Risk Factor Limit Results: As an outcome of the simulation, it is found that the available safe egress time (ASET) on the ground floor is 220 seconds in closed windows condition (Scenario 1) and 230 seconds in open windows condition (Scenario 2). The available safe egress time (ASET) in the ladies' section is found as 130 seconds for in closed windows condition (Scenario 1), 150 seconds for in open windows condition (Scenario 2). It is concluded that in open windows condition ASET time is increased respectively 10 seconds and 20 seconds for ground and first floor. Conclusion: Using operable windows in mosque dome drums with open condition increases available safe egress time (ASET) by exhausting the smoke in a fire.  Fire simulation in the domed mosque  The effect of the dome drum windows (i.e. open or closed) on fire safety Examination of the available safe egress time (ASET) in 750 kW fire in the Type 6 Mevlana Mosque with a capacity of 750 people Keywords:  domed mosque design  dome drum windows  fire analysis in mosques  fire dynamics simulation  pyrosim

“…According to Khandoker et al (2018) [51], the generated heat, smoke density, and toxicity concentration constitute the main features that affect the occupants' movement. Therefore, the FDS simulations are integrated into Pathfinder to consider humans' movement during the fire.…”

Building fires constitute a significant threat that affects property, the environment, and human health. The management of this risk requires an efficient fire evacuation system for buildings’ occupants. Therefore, a smart fire evacuation system that combines building information modeling (BIM) and smart technologies is proposed. The system provides the following capacities: (i) early fire detection; (ii) the evaluation of environmental data; (iii) the identification of the best evacuation path; and (iv) information for occupants about the best evacuation routes. The system was implemented in a research building at Lille University in France. The results show the system’s capacities and benefits, particularly for the identification of the best evacuation paths.

“…The simulation results show that the sprinkler prevents the fire from slowing down and increases people's evacuation time [7]. A fire was simulated in a garment factory [8]. The results showed that after 6s from the start of the fire, the smoke spread on the floor and stairs and reached the upper floors, making the situation critical for the residents.…”

The study of temperature and visibility in the parking of the commercial complex was done by Fire Dynamic Simulator code with various fire accident. Specification fire of parking were obtained in different fan system conditions. Temperature and visibility of a stairwell on various conditions were contrasted. The values were obtained at a height of 1.6m. The results showed that in the first state, temperature and visibility reached 80°C and 1 meters in 1200s after the fire, respectively. In the second state, visibility reached 6.34m in 1200s, which was 6.34 times better than the first state. The temperature also decreased to 51.11°C in 1200s. The temperature improved by 36.19% compared to the first state. In the third state, after 1200s, the temperature decreased 44.72°C. In the third state, the visibility was 15.59m, which improved 15.59 times the first state
