Reducing the contact time of an impacting droplet is highly desirable in various industrial fields including anti-icing. With the straightforward upscaling advantage, singularities on superhydrophobic surfaces can induce an annular rebound with a limited reduction in contact time. To break this limitation and further reduce contact time, this study focuses on optimizing the singularity number and arrangement.

Article Synopsis
  • This study examines how water droplets interact with superhydrophobic flexible cantilever beams, focusing on the dynamics between the oscillating substrate and droplet impact.
  • It finds that the deflection of the beam increases with the droplet's impact intensity (Weber number) but decreases with beam stiffness, while the droplet's spreading is not influenced by beam oscillations.
  • The research suggests that the cantilever beams can affect whether droplets bounce off or stick, depending on the stiffness of the beams, offering insights for innovative applications like anti-icing and self-cleaning technologies.

Bouncing dynamics of a trailing drop off-center impacting a leading drop with varying time intervals and Weber numbers are investigated experimentally. Whether the trailing drop impacts during the spreading or receding process of the leading drop is determined by the time interval. For a short time interval of 0.
