The impact of liquid drops on solid surfaces is ubiquitous in nature, and of practical importance in many industrial processes. A drop hitting a flat surface retains a circular symmetry throughout the impact process. Here we show that a drop impinging on Echevaria leaves exhibits asymmetric bouncing dynamics with distinct spreading and retraction along two perpendicular directions. This is a direct consequence of the cylindrical leaves that have a convex/concave architecture of size comparable…

Experimental and numerical results show that ellipsoidal shapes create the synergy effect of a preferential flow along the curved side, thereby leading to a significant reduction in the residence time when the drop's major axis coincides with the cylinder's axial direction.

Variation of the Contact Time of Droplets Bouncing on Cylindrical Ridges with Ridge Size.

The crossover between the two regimes is investigated and it is explained why the contact time is minimized when the radii of the drop and the cylindrical obstacle are comparable.

Droplet Asymmetric Bouncing on Inclined Superhydrophobic Surfaces

It is shown that a drop impacting on inclined superhydrophobic surfaces exhibits an asymmetric rebound with a distinctive spreading and retraction along the lateral and tangential directions, which endows a fast drop detachment.

Triggering of flow asymmetry by anisotropic deflection of lamella during the impact of a drop onto superhydrophobic surfaces

A water drop impacting a superhydrophobic surface (SHS) rebounds completely with remarkable elasticity. For a given drop size, the time of contact on a flat SHS remains constant. However, recent

Symmetry-Breaking Drop Bouncing on Superhydrophobic Surfaces with Continuously Changing Curvatures

The underlying principle of modifying the residence time via the drops’ ellipticity and initial surface curvature is elucidated based on momentum asymmetry and will offer practical implications for enhanced heat transfer performances and controlled water repellency, etc.

Controlling the residence time of a bouncing drop with asymmetric shaping.

This study investigates the bouncing dynamics of egg-shaped footprint drops to prove the concept of controlling the residence time with asymmetric shaping in an electrohydrodynamic device and describes the exceptional impact dynamics and the reduced contact time.

Triggering flow asymmetry by lamella deflection during drop impact on superhydrophobic surfaces

Water drop impacting a superhydrophobic surface (SHS) rebounds completely with remarkable elasticity. For such an impact, the balance between the inertial and capillary forces ascertain the contact

Bouncing dynamics of liquid drops impact on ridge structure: an effective approach to reduce the contact time.

A ridge structure is designed that can induce the drop to rapidly rebound through the combination effect of centre-drawing recoil and the resulting faster retraction velocity, which would open up a new way to reduce the contact time and control the bouncing dynamics of metal drops.

The experimental result shows that the bouncing of the ellipsoidal drop can reduce the contact time and maximum bounce height below the spherical one by at least 30% and 60%, respectively.

Abstract Droplets impinging on solid surfaces, as well as the countless varieties of the resulting possible dynamics, are found frequently in both natural and industrial environments. Among such

Dynamics of collapse of air films in drop impact.

Nanometer- and microsecond-resolved dual wavelength interferometry reveals a complex evolution of the interface between the drop and the gas layer underneath that eventually leads to the nucleation of solid-liquid contact at a The authors-dependent radial position, from a film thickness >200  nm.

Pancake bouncing on superhydrophobic surfaces

By designing surfaces with tapered micro/nanotextures which behave as harmonic springs, the timescales become independent of the impact velocity, allowing the occurrence of pancake bouncing and rapid drop detachment over a wide range of impact velocities.

This work uses mesoscale simulations and theoretical arguments, compared to experimental data, to show that "pancake bouncing" occurs when impacting fluid that enters the surface is slowed and then expelled by capillary forces.

Drop impact and rebound dynamics on an inclined superhydrophobic surface.

Investigating the impact and rebound dynamics of a drop at various liquid viscosities, in an isothermal environment, and on a nanocomposite superhydrophobic surface at normal and oblique impact conditions revealed that oblique and normal drop impact behaved similarly (in terms of maximum drop spread as well as rebound dynamics) at low normal Weber numbers.
