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 More >
