| Резюме: | Title screen The results of the experimental studies of collisions of water and water suspension droplets in a gas medium using high-speed video recording and specialized software for tracking the initial droplets and the resulting fragments were presented. Videograms that illustrate the typical drop collision modes (bounce , separation, coalescence, and disruption) were given. The effects of droplet collisions under free fall conditions in air at ambient temperature (20°C) and during their motion in the counter-flows of heated air (500°C) and combustion products (800–850°C) were considered. A statistical analysis of collision modes was performed. The dependences of their occurrence on some factors (size, rate, collision angle, and criterial expressions that include the dimensionless linear and angular interaction parameters) were presented. The ranges of fluid surface area during fragmentation and separation of droplets due to collisions in gas media with different temperatures were determined.
