Flame spread over porous sand beds wetted with propenol
A comprehensive set of experiments was carried out to investigate the spread of flames over porous sand beds wetted with finite quantities of propenol. The aim was to examine the key characteristics of flame propagation over porous beds when a limited supply of liquid fuel to the flame zone was available. Experiments were conducted over beds with depths ranging from 13.3 to 39.9 mm and average particle diameters between 0.5 and 5 mm under quiescent, assisted and opposed airflow configurations. It was found that the flame spread rate for both assisted and opposed airflow configurations dramatically decreased as the air speed was increased although the extent of decay in the flame spread rate was more pronounced in the case of the opposed airflow configuration. The experimental observations were explained by correlating the flame spread rate with the Damköhler number and fuel consumption flux. The practical implications of the findings are briefly discussed in this paper. Copyright © 2010 John Wiley & Sons, Ltd.
