Post-bushfire damage assessments show no significant reduction in property when compared with past bushfire events. Other than the severity of attack and behaviour bushfires, architectural design houses, construction materials and, many other factors affect house ignition. These are generally ignored simulations using simplified models. An improved risk assessment can be conducted if exact surr...

Yangının seyrinin ve oluşacak koşulların önceden bilinmesi, yangına karşı güvenli bina tasarımlarında geliştirilecek stratejilerin doğruluğu uygulanabilirliği bağlamında yol gösterici olmaktadır. Bu bağlamda performans analizlerine dayalı yangın güvenlik tasarımları, olaylarının gelişimini sonuç ürünlerinin yayılımını izlemeye yardımcı olan yöntemlerdendir. Yangına tasarımında yetkin yeterli ge...

Smoke simulation is an interesting topic in computer graphics these days. The realistic rendering of smoke scene is one of the most challenging tasks in fluid dynamics of computer graphics. Smoke simulation rendering is based on basics particle system. In this paper, our proposed method based on FDS’s (Fire Dynamic Simulation) output the result of the Excel file which improves DirectX for effec...

Abstract A pressing issue in managing the risks of wildfires mountain regions world is improving management rainfall intensity over their territories. The relative humidity air which precipitation should be initiated an important factor effectiveness such techniques. In mountains, forced convection on windward slopes has led to a significant increase rainfall. At same time, entering downwind re...

In this paper, using the numerical simulation analysis software MATLAB and Fire Dynamics Simulation (FDS), corresponding gas leakage diffusion model turbulence module were used to study law fire hazard of vinyl chloride monomer after in different atmospheric environments. The concentration distribution results for obtained by compared analyzed. area is defined hot gas, influence gas-phase oxida...

Along with simulated firefighting training, the development of virtual training systems and associated content has recently drawn attention as an alternative method for advanced training. In particular, to develop content, it is important understand combustion characteristics indoor combustible materials appropriately simulate their behavior. this study, seven types building fires were selected...

Bu çalışmada hastane binalarında yangın anında kullanıcıların tahliyesi ve dumandan etkilenme oranlarının simülasyon destekli olarak incelenmesi için HAD tabanlı simülasyonu Fire Dynamic Simulator (FDS) ile birlikte tahliye kullanılarak, yatay tahliye, asistanlı gibi binalarına özel olanaklarının irdelenmesi hedeflenmiştir. Yangın simülasyonunda ilgili yönetmelik standartlarda belirtilen yükler...

This paper lists the recent developments in the FDS+Evac evacuation model. FDS+Evac is an agent based emergency egress simulation model which is embedded in the fire simulation program FDS, thus, enabling simultaneous simulation of the fire and egress processes. The main new feature of the evacuation module is better treatment of different behavioral types of the evacuees using herding type alg...

In this study spread of smoke from a possible fire in University building and the evacuation time occupants were simulated. Fire dynamic simulations (FDS) have been done for natural forced with different scenarios; at same time, also various scenarios exits building. While move through changing CO, CO2, O2 concentrations, Fractional Effective Dose (FED) was gathered to obtain results both simul...

In this paper, performance-based fire-protection design is used for the fire-safety of public amenities with restrained personnel activities. these places, tourists’ activities are constrained in a limited space such as cockpit moving along track. Since it another typical scenario problem that cannot fully comply current mandatory codes and regulations, simulation analysis order to ensure fire ...
