Fences and mulch contribute to the spread of WUI fires. They act as both ignition targets and as sources that may themselves ignite nearby objects through direct flame contact and firebrand generation. The linear nature of fences gives them the capability

Role of Accumulation for Ignition of Fuel Beds by Firebrands

July 10, 2020
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Large outdoor fires are one of the prominent fire problems in the world. Spot fires, caused by firebrands, are known as a key mechanism of rapid fire spread. Firebrands ignite unburned fuels far ahead of fire front. In large outdoor fires, firebrands are

Determining Flow Resistance through Vegetation Canopy

Ryan L. Falkenstein-Smith, Kevin B. McGrattan
This study documents the measurement of the wind resistance of different types of vegetation. The measurements are made in a wind tunnel with a 2.0 m test section and 0.5 m by 0.5 m cross- section. Samples of vegetation have been cut into cubical volumes

Influence of Board Spacing on Mitigating Wood Decking Assembly Ignition

November 17, 2019
Author(s)
Samuel L. Manzello, Sayaka Suzuki
As part of recent building code change discussions, it has been suggested that by increasing the spacing of boards, it may be possible to mitigate ignition of wood decking assemblies from wind-driven firebrand showers. An experimental series was undertaken

Role of Firebrand Combustion in Large Outdoor Fire Spread

October 4, 2019
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Michael Gollner, A C. Fernandez-Pello
Large outdoor fires are an increasing danger to the built environment. Wildfires that spread into com- munities, labeled as Wildland-Urban Interface (WUI) fires, are an example of large outdoor fires. Other examples of large outdoor fires are urban fires
