Numerical simulation of a vibrating sessile droplet

The software enabling the description of behavior of a free surface and a contact line of a sessile droplet was developed. Linear forced oscillations of a viscous liquid droplet placed on a horizontal vibrating substrate were investigated numerically. The problem was solved: (1) for the pinned contact line; (2) for cases with constant contact angle. Resonant frequencies for the three first basic modes were found. The numerical results showed good agreement with the ones found in the literature.
