This paper presents the results of experimental investigations of deceleration and entrainment OF water droplets moving in a counterflow of high-temperature combustion products of liquid fuels and flammable liquids. High-speed video cameras and panoramic optical methods (Particle Image Velocimetry, Stereoscopic Particle Image Velocimetry, Particle Tracking Velocimetry, Shadow Photography) were applied to record the parameters of movement and evaporation of water droplet flows. To generate the combustion products with a high controlled temperature (400–1900 K), some typical oils, gasoline, kerosene, acetone, and industrial ethanol were used. This paper generalizes the results of investigations by establishing for droplets and gases the ranges of Reynolds number variation within which complete droplet deceleration and removal by drift is possible.
