Article

We have made experimental studies of the processes of deformation of drops (of size up to 6 mm) of three liquids with different physical properties (water, ethanol, kerosene) in motion in a gaseous medium (air) with velocities of up to 5 m/s. The most typical forms of drops have been distinguished, and the cyclic character of their change in traveling in a gaseous medium to distances of up to 1 m has been established. The characteristic "deformation cycles" in the process of motion have been determined, and the time intervals of the form change within each "deformation cycle" have been established. The maximum deviations of drop sizes from the initial ones have been calculated, and the influence of their sizes and velocities on the basic characteristics of the deformation have been determined.
