Аннотация:The fine structures of the spreading of a substance of free drop falling into a deep liquid are
studied by photo registration with high spatial and temporal resolutions. More than 500 experiments
are performed in a wide range of basic dimensional parameters as a result. A discrete distribution of
the droplet substance over the deformed surface of the target liquid for miscible liquids and a uniform
distribution for immiscible ones are shown. The discrete pattern is formed by a set of fine filaments,
namely, ligaments formed by droplet substance. A general scheme for the spreading of a droplet substance
is proposed for the case of interaction of miscible liquid pairs. Effects of Weber and Ohnesorge
numbers, the relative difference in surface tension coefficients, and the bottom topography on the flow
pattern structure are defined.
