Dynamic Wetting Behavior of Vibrated Droplets on a Micropillared Surface

Figure 5

The transient evolution of the droplet and amplitude prior to the droplet bouncing-off. (a) The droplet height , (b) the droplet contact diameter , and (c) the CA . The characteristics of the vibrated droplet on the pillared surface can generally be classified into three different categories: compression process (A)–(C), restoring process (C)–(E), and bouncing process (E)–(G).
