Flame propagation over liquid alcohols - Part III. Pulsating regime

The pulsating regime of flame spreading liquid fuels has been experimentally characterized. The mechanism that produces this oscillating behavior has been proposed, that correlates very well with our experimental data. The existence of a preheated region preceding the flame has been found; the characteristic horizontal length has also been experimentally measured. The transition temperatures have been found to possess common features for all fuels and geometrical configurations used in our experiments that can be used to improve fire safety in fuel containers.
