THE COMBUSTION OF THIN LAYERS OF LIQUID FUEL ON METALLIC SUBSTRATES

摘要

The results of experimental study of flame spread over thin layers of heptane, ethanol, and ethanol azide at contact of the liquid fuels with thin copper wires are presented. It was shown, that the velocity of flame decreases with growth of diameter of wire. The values of top and bottom limit of flame spread on diameter of wire depend on a boiling point of liquid fuel and its latent heat of evaporation. The mechanism of flame spread is depended both on heat conductivity and from a ratio of heat capacity of fuel and a substrate.
