With the Government of China's proposed Energy Efficiency Regulations (GB40411-2007), the implementation of external insulation systems will be mandatory in China. The frequent external insulation system fires cause huge numbers of casualties and extensive property damage and have rapidly become a new hot issue in construction evacuation safety in China. This study attempts to reconstruct an ac...

The water spray systems are effective protection systems in the confined or unconfined spaces to avoid the damage to building structures since the high temperature when fires occur. NFPA 15 and 502 have suggested respectively that the factories or vehicle tunnels install water spray systems to protect the machinery and structures. This study discussed the cooling effect of water spray systems i...

For the emergency evacuation of cruise ships in case sudden fire, this research proposes a dynamic route optimization method based on improved A∗ algorithm for real-time information, order to obtain optimal route. Initially, basic network topology diagram is established according internal structure ship. Before occurrence accident, can be applied an priori consisting all routes from each node e...

Pool fires cause immense damage to fuel storage tank farms. Reduced fire escalation risk in farms improves safety. Computational fluid dynamics (CFD) has proven effective assessing of fire-related domino effects and is being utilized for pool consequences The past CFD-based analysis focused on primary secondary targets. This study used simulator (FDS) model complete evolution the effect under d...

To thoroughly study the extinguishing effect of a high-pressure water mist fire system when transformer occurs, 3D experimental model is established in this work by employing Fire Dynamics Simulator (FDS) software. More specifically, setting different parameters, process with presence both diverse ambient temperatures and sprinkler laying conditions simulated. In addition, employed implementati...

This paper presents a detailed experimental and numerical study on the interaction, at reduced scale, between turbulent buoyant propane flame of about 15.5 kW water mist spray with flow rate 0.43 L/min from nozzle positioned 1 m above burner. The has been characterized experimentally without fire, by measuring mass flux droplet size distributions level burner surface. whole assembly was install...

Numerical simulations are performed to investigate the classical compartment fire problem involving a single door opening. Three different configurations were considered, namely full-scale (ISO 9705), an intermediate and small-scale enclosure with various opening heights widths. A large number of numerical was carried out using CFD code Fire Dynamics Simulator (FDS)(version 6.7.0). Based on var...

Computational Fluid Dynamic (CFD) modeling applications of the biomass gasification process help to optimize the gasifier. This study aims to investigate the impact of several physical parameters on the behavior of gasification in a fixed-bed downdraft gasifier. To that end, the study presents a comparison of the results computed using the Fire Dynamics Simulator (FDS) model with experimental r...

Fire is the most commonly occurring major accident hazard in chemical and process industries, with industry statistics highlighting liquid pool fire as frequent event. Modelling of such phenomena feeds heavily into risk assessment consequence analyses. Traditional simple empirical equations cannot account for full range factors influencing behaviour or increasingly complex plant design. The use...
