Abstract
By means of high-speed video registration, the cross-correlation system, and panoramic optical methods of trace visualization, experimental estimation of the influence of liquid (water) droplet evaporation on the conditions of droplet movement (acceleration and deceleration) through the high-temperature (about 1100 K) gases was made. The experiments were conducted with droplets about 1–6 mm in diameter at start velocities of 1–5 m/s. We compare the integral characteristics of the droplet movement in the air at a temperature of about 300 K (in the ongoing flow and through the steady gas medium) and in the combustion product flow at a temperature of about 1100 K. The gas and the air flow velocities were about 1.5 m/s. The typical difference in the droplet velocities under essentially different ambient temperatures was discovered. The contribution of water evaporation and the ongoing gas movement into droplet deceleration was discovered.
