An integrated environment was created to study the interaction among fire, heat transfer, and structural deformation from a typical room fire. The fire, thermal, and structural data were linked with a separate 3-D visualization capability, to provide the ability to visualize in real time the thermal and structural behavior of a chosen structural component in a room subjected to a typical fire i...

Purpose. The research based on FDS modeling aims to identify design parameters influence of the façade firefighting eaves at fire compartment border prevention spreading in high-rise buildings.Methods. To calculate temperature building model Pyrosim computer system is used which serves as user's shell application Fire Dynamics Simulator (FDS). This uses numerical algorithms solve complete Navie...

For assessing the performance of fire fighting means with emphasis on human actions, an integrated deterministic probabilistic safety analysis (IDPSA) was performed. This analysis allows for a quite realistic modelling and simulation of the interaction of the fire dynamics with relevant stochastic influences which refer, in the presented application, to the timing and outcome of human actions a...

Hermetic pressurized buildings have been developed to reduce the effects of high altitude. The behavior and effect fire in this new type building not studied before. Unlike common buildings, inside pressure is maintained at around standard atmospheric pressure, which significantly higher than outside environment altitude regions. In addition, early stage a fire, oxygen required maintain combust...

The efficiency of tunnels systems is often evaluated using numerical simulations. This concerns both to normal and emergency mode tunnel operation. Therefore the safety level users may depend on quality models being built. most studied areas cover researches natural forced airflows in fire development smoke spreading as well modeling fan Thus, many software packages implementing Computational F...

Fire accidents often lead to tremendous losses and smoke has been reported be the main cause of these heavy casualties. Accordingly, movement can influence escape confinement is particular significant. Dynamics Simulator software (FDS) was utilized carry out complementary full scale numerical simulations fire accident in a subway station. Different measure prevention exhaust were adopted differ...

Determining the input parameters for calibration of a water mist extinguishing system in compartment is important evaluation performance design. Although there lot research on use mist, it still difficult understand behavior terms safety people and protection things. In this study, we aimed to conduct an experimental analysis evaluate effectiveness systems protecting paintings art gallery museu...

Subway transportation is one of the most prevalent urban methods globally. Millions people around globe use this medium as their mode daily. However, subway stations may be highly prone to fire, smoke, or explosion accidents. The safety using demands a robust and practical framework assess fire hazards risks. This study provides methodology risk at station. integrates fault tree analysis (FTA) ...

In fire models, the accurate prediction of aerosol & soot concentrations in the gas phase and aerosol & soot deposition thicknesses in the condensed phase is important for a wide range of applications, including human egress calculations, heat transfer in compartment fires, and forensic reconstructions of fires. During a fire, in addition to soot transport by advection and diffusion, a signific...
