Abstract
This article presents the results of experimental investigations of the evaporation of water droplets under velocity conditions through atypical combustion of flammable liquids and oil products. The studies were focused on creating an experimental basis, sufficient for the development of the basic elements of fire extinguishing technologies using atomized water. It is established a determining influence of the sizes of generated droplets and initial velocities of their movement on the intensity of heating and evaporation of the droplets in the stream of high-temperature combustion products of gasoline, kerosene, and commercial alcohol. The results of experimental studies with the known model of heat and mass transfer are compared. An approximate expressions to predict the velocities of evaporation of water droplets in the combustion products of typical flammable liquids and oil products are determined. It is distinguished an opportunity to fairly simple assess of necessary and sufficient conditions for the complete evaporation of the water in the flames of oil products (at a known temperature of the flame).
