Abstract The structure of the flow and the acoustic signals generated by the
impact of a freely falling drop of water with an underlying quiescent fluid have
been investigated for droplets having diameter 0.5 cm and a contact velocity in
the range 1.5 < U < 5 m/s. The experimental study has been supported by
high-resolution videos of the flow (as seen from above and from the side). The
evolution of ejecta, spikes, droplets spray, cavity, splash, secondary cavity, streamer, secondary droplets and sequence of capillary waves is reported accordingly.
In particular, perturbations of the smoothed… More >
