Area of Science:

  • Fluid dynamics
  • Soft matter physics
  • Surface science

Background:

  • Contact line fluctuations of large drops are typically blocked by substrate hysteresis.
  • Slow modes of free contact line motion are unobservable due to pinning effects.

Purpose of the Study:

  • To investigate the effect of vertical substrate vibrations on the contact line of large liquid drops.
  • To determine the conditions under which vibrations can overcome hysteresis and induce contact line motion.

Main Methods:

  • Subjecting liquid drops to controlled vertical vibrations with varying frequency and acceleration amplitude.
  • Observing and analyzing the resulting contact line dynamics and oscillations using imaging techniques.

Main Results:

  • A threshold vibration acceleration amplitude (Lambda(c)) was identified to overcome contact line pinning.
  • Vertical vibrations excite contour oscillations (triplons) at harmonic modes and subharmonic frequencies (omegaE/2).
  • The phase diagram of subharmonic modes and their growth dynamics near instability thresholds were mapped.

Conclusions:

  • Vertical substrate vibrations are an effective method to release pinned contact lines and induce dynamic behaviors.
  • The study reveals a new route to control droplet dynamics and explore instabilities in soft matter systems.
