Abstract

The magnitude of destruction from fire spread processes are hard to imagine during large outdoor fire outbreaks. Even though these disasters are of great public concern and intense media interest, much knowledge is still needed to validate computational models of the complex ignition processes in large outdoor fires. In this context, wind-driven showers of smoldering wood particles of varying sizes were directed at fuel beds exposed to radiant heat flux. The influence of smoldering particle size for a fixed applied radiant heat flux level to a fuel bed was studied to observe subsequent ignition behavior. Results of this study are discussed.
