Experimental investigation of the main characteristics of water droplet "strain cycles" during their motion the gas area
The experimental investigation of the main characteristics of water droplet deformation during their motion through the gas area was conducted by using the panoramic optical methods, cross-correlation complex and high-speed (up to 100 000 frames per second) camera. Droplet sizes were varied in the range 3-6 mm, motion velocities - from 1 m/s to 5 m/s. The air was considered as a gas area. The characteristic "strain cycles", lengths and durations of droplets were indicated. Deformation ranges and life times of droplets in the shape of a sphere, ellipsoid and other rotation bodies were determined. The influence of droplet sizes and their motion velocities on the characteristics of "strain cycles" was established. The recommendations of choosing the droplet shapes at numerical simulation of their motion in gas areas with significant subsonic velocities were formulated.
