Fig. 3: Energy changes during droplet impact by numerical simulation.
From: Suppression of hollow droplet rebound on super-repellent surfaces
a, b Energy changes of the SD (a) and HD (b) at an impact velocity of V0 = 0.135 m s−1. The SD bounces while HD rests on the surface after impact. Ek, Ep, Es, Et represent kinetic energy, potential energy, surface energy, and their sum, respectively. Et = Ek + Ep + Es. c, d Energy changes of the SD (c) and HD (d) at a higher impact velocity of V0 = 0.270 m s−1. Both SD and HD bounce off the surface after impact.
