On the Use of a Firebrand Generator to Investigate the Ignition of Structures in Wildland-urban Interface (wui) Fires
An experimental apparatus has been constructed to generate a controlled and repeatable size and mass distribution of glowing firebrands. The present study reports on a series of experiments conducted in order to characterize the performance of this firebrand generator. Firebrand generator characterization and subsequent structural ignition experiments were performed at the Fire Research Wind Tu...

متن کاملFirebrands and spotting ignition in large-scale fires
Spotting ignition by lofted firebrands is a significant mechanism of fire spread, as observed in many largescale fires. The role of firebrands in fire propagation and the important parameters involved in spot fire development are studied. Historical large-scale fires, including wind-driven urban and wildland conflagrations and post-earthquake fires are given as examples. In addition, research o...
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 کاملA dimensional analysis on firebrand penetration through a mesh screen.
A dimensional analysis on firebrand penetration through a mesh screen was carried out to correlate the experimental data previously reported in the literature. Three dimensionless variables, one dimensionless time and two dimensionless lengths, were obtained. The resulting dimensionless parameters correlated the data well and may provide a useful framework to assess firebrand penetration throug...
