A Perspective on Forest Fuel Bed Ignition by Firebrands
Jiann C. Yang
A different perspective on forest fuel bed ignition by firebrands is presented to obtain a correlation between the ignition time of a fuel bed by a glowing firebrand and fuel moisture content. A firebrand heating efficiency akin to spray cooling efficiency was introduced and used in the analysis. The idea of using a firebrand heating efficiency of a forest fuel bed coupled with proper dimensional analysis may offer an effective way to correlate prospective experimental fuel bed ignition data as function of fuel properties, fuel configuration, firebrand shower characteristics, and wind.
