Volatile drops deposited on a hot solid can levitate on a cushion of their own vapor, without contacting the surface. We propose to understand the onset of this so-called Leidenfrost effect through an analogy to nonequilibrium systems exhibiting a directed percolation phase transition. When performing impacts on superheated solids, we observe a regime of spatiotemporal intermittency in which localized wet patches coexist with dry regions on the substrate. We report a critical surface…

Drop impact on superheated surfaces: short-time dynamics and transition to contact

Abstract When a volatile drop impacts on a superheated solid, air drainage and vapour generation conspire to create an intermediate gas layer that delays or even prevents contact between the liquid

Drop impact on viscous liquid films

When a liquid drop falls on a solid substrate, the air layer in between them delays the occurrence of liquid–solid contact. For impacts on smooth substrates, the air film can even prevent wetting,



Dynamic Leidenfrost Effect: Relevant Time and Length Scales.

The processes responsible for the transitional regime between the fully wetting and the fully levitated droplet as the solid temperature increases are revealed, thus shedding light on the characteristic time and length scales setting the dynamic Leidenfrost temperature for droplet impact on an isothermal substrate.

The cold Leidenfrost regime

It is discussed here how heat enhances superhydrophobicity by favoring a “cold Leidenfrost regime” where water adhesion becomes nonmeasurable even at moderate substrate temperature.

Experimental realization of directed percolation criticality in turbulent liquid crystals.

Developing an experimental technique to create a seed of topological-defect turbulence by pulse laser, this report confirms in particular the rapidity symmetry, which is a basic but nontrivial consequence of the field-theoretic approach to DP.

How ambient conditions affect the Leidenfrost temperature.

This work investigates the dependence of the Leidenfrost temperature on the ambient conditions and proposes a rescaling of the temperature which allows to collapse the curves for various organic liquids and water onto a single master curve, which yields a powerful tool to predict TL.

Leidenfrost drops

A Leidenfrost drop forms when a volatile liquid is brought in contact with a very hot solid. Then, a vapor film comes in between the solid and the drop, giving to the latter the appearance of a

Wetting under nonequilibrium conditions.

A mean-field approximation is shown to reproduce the main features of the phase diagram of a recently introduced model for nonequilibrium wetting in (1+1) dimensions, while providing indications for the behavior of the wetting transition in higher dimensions.

Stabilization of Leidenfrost vapour layer by textured superhydrophobic surfaces

Topological texture on superhydrophobic materials is critical in stabilizing the vapour layer and thus in controlling—by heat transfer—the liquid–gas phase transition at hot surfaces, and can potentially be applied to control other phase transitions.

Directed percolation criticality in turbulent liquid crystals.

This work experimentally investigates the critical behavior of a phase transition between two topologically different turbulent states of electrohydrodynamic convection in nematic liquid crystals, providing the first clear and comprehensive experimental evidence of an absorbing phase transition in this prominent nonequilibrium universality class.

The thermo-wetting instability driving Leidenfrost film collapse

This work investigates the vapor film instability for small length scales that ultimately sets the collapse condition at the Leidenfrost point of a fluid, and proposes an ab initio, mathematical expression for theLeidenf Frost point of the LFP.
