Rescue and evacuation of underground interchange tunnels after a fire are challenging. Therefore, method integrating building information modeling (BIM) dynamic simulator (FDS) was proposed to analyze characteristics personnel escapes in tunnels. A BIM model built, then different formats (DXF CAD) were generated imported into Pyrosim software Pathfinder software. With an increase ventilation ve...

Purpose The purpose of this paper is to propose a simplified representation the fire load in computational fluid dynamics (CFD) represent effect large-scale travelling and highlight relevance such an approach whilst coupling CFD results with finite element method (FEM) evaluate related steel temperatures, comparing numerical outcomes experimental measurements. Design/methodology/approach This p...

temporal and spatial variations of fire behavior can be predicted using one of the semi-physical or empirical models developed over recent years. this article investigates the effect of different fuel moisture conditions on fire spread and behavior in national golestan park in july 2011 using farsite, flammap simulation systems, and previous ignition history. landscape data contains the topogra...

The University of California's Department of Forestry and Resource Management, under contract with the California Department of Forestry and Fire Protection, has developed and released the first version of the California Fire Economics Simulator (CFES). The current release is adapted from the Initial Action Assessment component of the USFS's National Fire Management Analysis System and features...

The challenge of modelling a well characterized full-scale fire test using computational fluid dynamics is illustrated in this work comparing a priori and a posteriori simulations. In 2006, The Dalmarnock Fire Tests were conducted in two identical 3.5 m 4.75 m 2.5 m concrete enclosures with a real residential fuel load. This data set provides measured data at the highest spatial resolution avai...

Abstract The increasing demand for Liquified Natural Gas (LNG) is directly proportional to the risk of LNG Facilities. One risks fire due leakage storage tank at terminal. This study aims predict impact jet on humans leaks tanks using Fire Dynamic Simulator and probability injury or death accident. simulation uses capacity as variations including primary data obtained from field surveys. first ...

Wildfires release the greatest amount of carbon into the atmosphere compared to other forest disturbances. To understand how current and potential future fire regimes may affect the role of the Eurasian boreal forest in the global carbon cycle, we employed a new, spatially-explicit fire module DISTURB-F (DISTURBance-Fire) in tandem with a spatially-explicit, individually-based gap dynamics mode...

Since the tragic event of World Trade Centre (WTC), efforts to understand realistic fire behaviour in tall buildings are accelerated. It is critical dynamics involved a compartment before performing forensic investigation accident. In this paper, various scenarios considered simulate high-rise building and demonstrated case Plasco Building using computationally fluid (CFD). Two fuel distributio...

simulation study using Fire Dynamic Simulation (FDS) has been conducted on a simplified car park model. As this work aims to analyse the effectiveness of natural ventilation in dissipation smoke, all models’ dimensions and opening size corresponded Uniform Building by Law (UBBL) 1984 requirements, which allowed models be without any mechanical system or alarm. The fire source is produced modell...
