When a drop of a viscous fluid is deposited on a bath of the same fluid, it is shown that its coalescence with this substrate is inhibited if the system oscillates vertically. Small drops lift off when the peak acceleration of the surface is larger than g. This leads to a steady regime where a drop can be kept bouncing for any length of time. It is possible to inject more fluid into the drop to increase its diameter up to several centimeters. Such a drop remains at the surface, forming a large… 
Ultra-Hydrophobic Water
When a drop of a viscous fluid is deposited on a bath of the same fluid that is vibrating, it is shown that it coalesces with this substrate or lifts off when the vibration of the surface is larger
Metastable bouncing droplets
An oil droplet is placed on an oil bath at least ten times more viscous. When the oil bath is vertically shaken according to a sinusoidal motion, the droplet may bounce indefinitely on the bath. This
From bouncing to boxing.
The experiments have shown that the deformation of the droplet has to be taken into account to explain the bouncing, and some resonance effects have been observed, i.e., a decrease of the threshold acceleration at given frequencies: various deformation modes may be excited.
Bouncing jet: a Newtonian liquid rebounding off a free surface.
It is found that a liquid jet can bounce off a bath of the same liquid if the bath is moving horizontally with respect to the jet, and the bouncing phenomenon exhibits hysteresis and multiple steady states.
Controlling the partial coalescence of a droplet on a vertically vibrated bath.
Results suggest that the limit size for bouncing is related to the first mode of the droplet deformation, which is similar to the acceleration and the frequency of the bath vibration.
Aerodynamic Leidenfrost effect
When deposited on a plate moving quickly enough, any liquid can levitate as it does when it is volatile on a very hot solid (Leidenfrost effect). In the aerodynamic Leidenfrost situation, air gets
Drops can bounce from perfectly hydrophilic surfaces
Drops are well known to rebound from superhydrophobic surfaces and from liquid surfaces. Here, we show that drops can also rebound from a superhydrophilic solid surface such as an atomically smooth
Leidenfrost drops on a heated liquid pool
We show that a volatile liquid drop placed at the surface of a non-volatile liquid pool warmer than the boiling point of the drop can experience a Leidenfrost effect even for vanishingly small
Dimple drainage before the coalescence of a droplet with a smooth substrate
C is a major process in multiphase flows since it controls, with the break-up dynamics, the global evolution of the number of droplets and bubbles in the flow. It is therefore crucial for spray
Deceleration of droplets that glide along the free surface of a bath
A droplet obliquely impacting a bath surface of the same fluid can traverse along the interface while slowing at an exponential rate. The droplet rests on a thin film of air, deforms the bath surface


Levitation of a drop over a film flow
A vertical jet of water impinging on a horizontal surface produces a radial film flow followed by a circular hydraulic jump. We report a phenomenon where fairly large (1 mi) drops of liquid levitate
Suppression of coalescence and of wetting: The shape of the interstitial film
The shape of the interstitial air film between noncoalescing liquids and between a drop and a solid surface is detected by means of laser interferometry. Alternative optical techniques are exploited
▪ Abstract We examine situations in which two droplets of the same liquid may come into apparent contact without coalescing or in which a droplet that normally wets a surface may deform against it
Regimes of coalescence and separation in droplet collision
An experimental investigation of the binary droplet collision dynamics was conducted, with emphasis on the transition between different collision outcomes. A series of time-resolved photographic
Chaotic dynamics of a bouncing ball
An undergraduate experiment is described that illustrates the period doubling route to chaos in a simple dissipative mechanical system, a bouncing ball subject to repeated impacts with a vibrating
Jumping particle model. Period doubling cascade in an experimental system
An experimental model of a modification of the Fermi acceleration problem is described. Evidence is presented for three consecutive bifurcations on the period doubling route of the system from
