When a liquid drop contacts a wettable surface, the liquid spreads over the solid to minimize the total surface energy. The first moments of spreading tend to be rapid. For example, a millimeter-sized water droplet will wet an area having the same diameter as the drop within a millisecond. For perfectly wetting systems, this spreading is inertially dominated. Here we identify that even in the presence of a contact line, the initial wetting is dominated by inertia rather than viscosity. We find…

Short time dynamics of viscous drop spreading
Liquid drops start spreading directly after coming into contact with a solid substrate. Although this phenomenon involves a three-phase contact line, the spreading motion can be very fast. We
Sharp acceleration of a macroscopic contact line induced by a particle
Wetting of a planar solid substrate is investigated in the presence of a macroscopic particle in the complete wetting regime. A drop of silicone oil spreads on the substrate and its macroscopic edge
Inertial to viscoelastic transition in early drop spreading on soft surfaces.
It is shown that a short, rapid spreading stage exists after initial contact and the requisite balance determining the speed of motion is between capillary forces and inertial effects.
Surface structure determines dynamic wetting
This work identifies how surface roughness influences the initial dynamic spreading of a partially wetting droplet by studying the spreading on a solid substrate patterned with microstructures just a few micrometers in size and reveals the roughness influence can be quantified in terms of a line friction coefficient for the energy dissipation rate at the contact line.
Effect of interfacial mass transport on inertial spreading of liquid droplets
In this work, the early time dynamics of low-viscosity liquid drops spreading in their saturated vapor on partially wetting surfaces are investigated by lattice Boltzmann numerical simulations.
Wetting dynamics in two-liquid systems: Effect of the surrounding phase viscosity.
A scaling law is developed where the three-phase contact line velocity is a function of both spreading radius and mean viscosity, close to the geometric mean of the droplet and ambient fluids' viscosities.
Spreading of a pendant liquid drop underneath a textured substrate
A pendant drop spreading underneath a partially wetting surface from an initial shape to its final equilibrium configuration and contact angle is studied. A mathematical formulation that quantifies
Universal spreading of water drops on complex surfaces.
This work experimentally investigates how these early stages of spreading are influenced by different types of surface complexity, including micro-textured substrates, chemically striped substrates and soft substrates.
Dissipation in rapid dynamic wetting
In this article, we present a modelling approach for rapid dynamic wetting based on the phase field theory. We show that in order to model this accurately, it is important to allow for a
Surface structure determines dynamic
Liquid wetting of a surface is omnipresent in nature and the advance of micro-fabrication and assembly techniques in recent years offers increasing ability to control this phenomenon. Here, we

It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
