ABSTRACT = {The interaction of a falling drop (diluted aqueous solution of ink in various concentrations) with a target fluid (partially degassed tap water) has been
tracked by means of high-resolution video recording and photography. The
experimental setup has carefully been prepared in order to preserve the axial symmetry of initial conditions. Three regimes of interaction have been identified
accordingly (depending on the drop velocity as controlled by the distance of fall):
rapid droplet coalescence, rebound with the conservation of the drop volume and
shape, and partial coalescence. Previous findings are recovered and confirmed,
and enriched with heretofore unseen observations of complex partial coalescence.
An extensive set of data is reported to support understanding of the observed
dynamics and their repeatability and reproducibility. The overall study has been
carried out with the express intent to spur the future development of detailed
mathematical models and numerical methods suited for this kind of problems.},
