lack of fire behavior studies and the immediate needs posed by the extent of the fire problem in forests of iran require that extensive studies be conducted to develop models to predict fire behavior in the region.in this study, farsite fire area simulator was applied to simulate spread and behavior of two real fires that had occurred in northern forests of iran during 2010 summer and fall seas...

Fire is known to be an important factor in many ecological systems [Whelan 1995]. In plant communities, the combined effects of opening up space, burning biomass, and releasing nutrients to the soil offer a variety changing environmental conditions. When burns are relatively frequent, and a stable burning regime has persisted on evolutionary time scales, many species develop specific responses ...

fire blight, a bacterial disease caused by erwinia amylovora (burr.) winslow et al. 1920 is considered as a serious disease on pome fruits. during recent years, this disease has caused serious damages to the fruit growing industry in iran. precise and reliable methods for identification and detection of the pathogen can help in its early control, prevent the disease spread and help eliminate th...

The purpose of this research was to introduce and describe a model for Fire Quantitative Risk Assessment of in petroleum Storage Tanks. A novel model was designed to determine the risk of a fire occurrence using of Loss Causation and Swiss cheese models. Then, based on FTA, model and its integration with our initial proposed model, the final model was obtained for fire hazard determination in h...

premixed combustion is widely used for reducing pollutant emission from combustion chambers. however, these systems may be sensitive to complex phenomena such as flashback. in the present study flame, flashback and structure of premixed laminar flames are investigated theoretically. the mathematical model includes the axi-symmetric continuity, navier stocks, energy, and species equations. combu...

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...

Electrical cable sheaths are the most abundant fire load in nuclear power plants, mainly rooms that kept under slight pressure. This configuration leads fires to grow under-ventilated and vitiated conditions. Assessing threat involves characterizing heat released, responsible for growth, smoke evolved, which may interact with sensitive components area. For purpose, a revisited controlled-atmosp...
