The purpose of this paper is to reveal the reasons for survival ancient villages in western Hunan face a long-term high risk fire, which has led their heritage status. study selected representative village region, High chair village, as case explain siting and layout. fire was investigated terms dwelling materials, structural forms, fire-related activities, street dimensions. Monitoring instrum...

Fires caused by cables occur frequently in mines, which endanger the safety of workers. To explore characteristics a multilayer cable fire mine tunnel, simulations were carried out using Fire Dynamics Simulator (FDS). The influence tray spacing, ignition position, and tunnel ventilation speed on studied. results showed that these factors change amount contact between air, heat accumulation, tra...

Nuclear power plants contain a significant amount of fire load in form of electrical cables. The performance of the cables is interesting both from the fire development and system failure viewpoints. In this work, cable tunnel fires are studied using numerical simulations, focusing on the fire spreading along power cables and the efficiency of the water suppression in preventing the cable failu...

Subsea gas release is an industrial hazard that can impose fire hazards on offshore facilities near the surfacing area. However, risk assessment of caused by subsea challenged due to inadequate recognition knowledge mechanism and resulting hazards. At present, minimal researches involving from a were reported, this paper extension previous works behavior. This focuses modeling release. A numeri...

The metro depot area has the characteristics of large and high storey smoke diffusion under fire conditions in these areas are more complicated. It is important to investigated exhaust effect which closely related safety firefighters. FDS (Fire Dynamics Simulator) numerical simulation method was adopted investigate influence draft curtain height on performance fan were installed inside wall are...

Historical buildings often fail to meet today’s building and fire protection regulations due their structure space restrictions. For this reason, if such encounter fire, serious damage will be resulted. The of the Notre-Dame Cathedral in Paris (Notre-Dame de Paris) April 2019 highlights seriousness problem. In study, historical “Tamsui Church” was selected as an example. Fire Dynamics Simulator...

Fire is defined as an extremely hazardous event, causing a threat to life and health of persons, but also damage the economic sphere. It has been shown many times that fire can occur anywhere at any time. In order minimize risk manifestations, it necessary understand its course. technical practice, computational models are used determine partial manifestations fire, such spread rate, smoke gene...

The use of Computational Fluid Dynamics (CFD) and in particular Large Eddy Simulation (LES) codes to model fires provides an efficient tool for the prediction of large-scale effects that include plume characteristics, combustion product dispersion, and heat effects to adjacent objects. This paper illustrates the strengths of the Fire Dynamics Simulator (FDS), an LES code developed by the Nation...

To figure out the influence of smoke-proof air curtains on law tunnel fire smoke spread, this paper set a simulated scene passenger bus with source power 25 MW in Fire Dynamics Simulator (FDS), software for stimulating dynamics, to study spread tunnels. At first, analyzed distribution temperature, visibility, and CO concentration each area under conditions different jet velocities angles curtai...
