The Intensification of Heat and Mass Transfer Processes in the Operating Condition of Automatic Fire Extinguishing Systems at Objects of Power

Abstract

Using the optical methods of “tracer” visualization “Particle Image Velocimetry” and “Interferometric Particle Imagine” were performed the experimental studies of the characteristics of evaporation of large single water droplets as they pass through the flames of flammable liquids – gasoline, kerosene, acetone, industrial alcohol, oil. Were determined the rates of evaporation of water under these conditions and the influence of droplet size, velocity of droplets and initial water temperature on the evaporation.
