Experimental determination of times, amplitudes, and lengths of cycles of water droplet deformation in air

The regularities of deformation of water droplets moving in air at the moderate Weber numbers (We $<$ 7) are experimentally investigated with the use of high-speed cross-correlation recording equipment at frame delays of less than 100 ns. Deformation cycles with characteristic times, amplitude, lengths, and droplet forms are established. The effect of the droplet velocity on the main characteristics of the deformation cycles is determined.
