Abstract

Abstract: We report on the results of experiments devoted to analysis of conditions and characteristics of “bounce” (approach and interaction through a gaseous buffer envelope) of water droplets moving in a gaseous media with different parameters: velocity and direction of motion, temperature, and composition. Experiments were performed in flows of air, water vapor, and combustion products. Peculiarities of bounce of droplets with different initial temperatures are considered, and the results obtained at 18–20 and 60–80°C are compared. More than 1000 collisions of droplets recorded by high-speed photography are divided into groups of bounce, coalescence, separation, and disruption. The results of criterion processing using the Weber numbers are obtained.
