The influence of solidification on the spreading of liquids is addressed in the situation of an advancing liquid wedge on a cold substrate at $T_p < T_f$, of infinite thermal conductivity, where $T_f$ is the melting temperature. We propose a model derived from lubrication theory of contact-line dynamics, where an equilibrium between capillary pressure and viscous stress is at play, adapted here for the geometry of a quadruple line where the vapour, liquid, solidified liquid and basal substrate…

We describe the aims and content of this issue.
Droplet impacts on cold surfaces
Abstract We study drop impact for the case where the impacted surface is cooled below the freezing temperature of the liquid droplet. The freezing is found to affect the spreading dynamics of the
Contact Line Catch Up by Growing Ice Crystals.
The effect of freezing on contact line motion is a scientific challenge in the understanding of the solidification of capillary flows. In this Letter, we experimentally investigate the spreading and
Solidification and dynamic wetting: A unified modeling framework
A conceptual and mathematical framework for the singularity-free modeling of non-equilibrium solidification/melting and non-isothermal dynamic wetting is developed where both processes are embedded


Liquid spreading on cold surfaces: Solidification-induced stick-slip dynamics
We study the contact line dynamics of a liquid drop on a substrate at temperature Ts colder than the freezing temperature Tm. The purpose is to determine experimentally the criterion for a
Motion and arrest of a molten contact line on a cold surface: An experimental study
An experimental study is presented of the behavior of a molten contact line under conditions which simulate what happens when a molten droplet touches a subcooled solid, spreads partly over it, and
On the theory for the arrest of an advancing molten contact line on a cold solid of the same material
We show that a conventional continuum formulation of the equations and boundary conditions for the spreading of a pure molten material over a cold, solid substrate of its own kind has no meaningful
Contact line arrest in solidifying spreading drops
When does a drop, deposited on a cold substrate, stop spreading? Despite the practical relevance of this question, for example, in airplane icing and three-dimensional metal printing, the detailed
Spreading and arrest of a molten liquid on cold substrates.
A physical hypothesis using scaling is provided to explain the relationship between the arrested base diameter and arrested contact angle with respect to the Stefan number and the experimental observations of solidified drops on cold substrates corroborate the derived physical theory.
Solid friction from stick–slip down to pinning and aging
We review the present state of understanding of solid friction at low velocities and for systems with negligibly small wear effects. We first analyze in detail the behavior of friction at interfaces
Numerical simulation of an evaporative meniscus on a moving substrate
A hydrodynamic model based on lubrication theory has been developed to describe an evaporative meniscus in a complete wetting configuration, when evaporation takes place in ambient air. We focus on
Evaporation-induced flow near a contact line: Consequences on coating and contact angle
We propose a simple model of the dynamics of a contact line under evaporation and partial wetting conditions, taking into account the divergent nature of evaporation near the contact line, as
Molten droplet deposition and solidification at low Weber numbers
Low Weber number deposition of small molten droplets on cold targets is of importance in certain dropwise buildup processes, but at this time, critical elements are absent from our theoretical
Universality of tip singularity formation in freezing water drops.
It is found that the cone angle is independent of substrate temperature and wetting angle, suggesting a universal, self-similar mechanism that does not depend on the rate of solidification.
