Smouldering and flaming of solid fuels both originate after the pyrolysis reaction, and fires
often transition between the two types of combustion. Smouldering-to-flaming (StF) transition
introduces a sudden increase of the fire hazard in terms of temperature, spread rate, and
power. The literature has studied the effect of wind on StF but only with continuous wind.
Here, we show for the first time the influence of pulsating wind by studying the StF transition
on wood samples that have been ignited and where smouldering is spreading. The time to …
