Numerical Prediction of Fire Propagation in Idealized Wildland and Urban Canopies
نویسنده
چکیده
Numerical methods are used to examine the development of fires within porous urban canopies. Idealized generic porous models of 2-D and 3-D city structures are used together with inserted heat sources to predict combined flow circulations. The presence of structures of different densities, height and distribution produce unique flowfields associated with the porous canopy structure of cities, but the buoyancy produced by combustion products modifies, and for large fires, dominates the urban canopy flow.

Coupled fire–atmosphere modeling of wildland fire spread using DEVS-FIRE and ARPS
This article introduces a new wildland fire spread prediction system consisting of the raster-based Discrete Event System Specification Fire model (DEVS-FIRE) and the Advanced Regional Prediction System atmospheric model (ARPS). Fire–atmosphere feedbacks are represented by transferring heat from DEVS-FIRE to ARPS as an externally forced set of surface fluxes and mapping the resulting changes in...
متن کاملScientific and social challenges for the management of fire-prone wildland--urban interfaces
At their worst, fires at the rural–urban or wildland–urban interface cause tragic loss of human lives and homes, but mitigating these fire effects through management elicits many social and scientific challenges. This paper addresses four interconnected management challenges posed by socially disastrous landscape fires. The issues concern various assets (particularly houses, human life and biod...

متن کاملPhysics-based Modeling of Wildland-urban Interface Fires
This paper addresses the development of a practical physics-based model for fires in the wildland-urban intermix. These fires arise when wildland burning invades the built environment. Fire models for ignition and spread must consider individual fuel elements of both vegetation and structures in order to assess fire risk of developed properties. Successful prediction of wildland fire spread has...
متن کاملThe High Park fire: Coupled weather-wildland fire model simulation of a windstorm-driven wildfire in Colorado's Front Range
Weather affects wildland fires at scales frommultiseasonal precipitation patterns and anomalies, through synoptic and mesoscale weather patterns, to convective scale motions including fire-induced winds. This work analyzed the first day’s growth of the 2012 High Park fire, which occurred in Colorado’s Front Range during widespread drought and an unseasonal June windstorm, assessing to what exte...
