INFLUENCE OF THE TEMPERATURE OF GASES ON THE DEFORMATION CHARACTERISTICS OF MOVING WATER DROPLETS

An experimental analysis of the infl uence of the temperature of gases on the deformation characteristics of water droplets moving through them is carried out. High-speed (up to 10⁵ frames per second) photography with video cameras and cross-correlation complexes, as well as panoramic optical methods of recording the motion parameters of gaseous and liquid flows, were used. The laws governing the movement of water droplets through gases with a temperature of about 1100 K and in air at relatively low (to 280 K) and moderate (about 300 K) temperatures have been studied. The principal characteristics of the deformation of water droplets (duration, extension, and amplitudes of "deformation cycles") have been established. The differences in the characteristic shapes of droplets during their motion in gaseous media (at different temperatures of the latter) have been determined. The times during which droplets retain a certain shape in the deformation process have been calculated
