Superhydrophobicity of Auxetic Metamaterials
Glen McHale, Andrew Alderson, Steven Armstrong +7
Superhydrophobic materials are often inspired by nature, whereas metamaterials are engineered to have properties not usually found in naturally occurring materials. In both cases,…
Modelling the Dynamics of Partially Wetting Droplets on Fibres
Raymond Christianto, Yudi Rahmawan, Ciro Semprebon +1
We simulate gravity driven dynamics of partially wetting droplets moving along a fibre using the lattice Boltzmann method. For the so-called clamshell morphology, we find three pos…
Apparent Contact Angle of Droplets on Liquid Infused Surfaces: Geometric Interpretation
Ciro Semprebon, Muhammad Subkhi Sadullah, Glen McHale +1
We theoretically investigate the apparent contact angle of droplets on liquid infused surfaces as a function of the relative size of the wetting ridge and the deposited droplet. We…
Capillary Bridges on Liquid Infused Surfaces
Alvin C. M. Shek, Ciro Semprebon, Jack R. Panter +1
We numerically study two-component capillary bridges formed when a liquid droplet is placed in between two liquid infused surfaces (LIS). In contrast to commonly studied one-compon…
Modelling double emulsion formation in planar flow-focusing microchannels
Ningning Wang, Ciro Semprebon, Haihu Liu +2
Double emulsion formation in a hierarchical flow-focusing channel is systematically investigated using a free energy ternary lattice Boltzmann model. A three dimensional formation…
Modelling ternary fluids in contact with elastic membranes
Marianna Pepona, Alvin C. M. Shek, Ciro Semprebon +2
We present a thermodynamically consistent model of a ternary fluid interacting with elastic membranes. Following a free-energy modelling approach and taking into account the thermo…
Wetting boundaries for ternary high density ratio Lattice Boltzmann Method
Neeru Bala, Marianna Pepona, Ilya Karlin +2
We extend a recently proposed ternary free energy lattice Boltzmann model with high density contrast, by incorporating wetting boundaries at solid walls. The approaches are based o…
Drop dynamics on Liquid Infused Surfaces: The Role of the Wetting Ridge
Muhammad Subkhi Sadullah, Ciro Semprebon, Halim Kusumaatmaja
We employ a free energy lattice Boltzmann method to study the dynamics of a ternary fluid system consisting of a liquid drop driven by a body force across a regularly textured subs…
Statics and dynamics of liquid barrels in wedge geometries
Élfego Ruiz-Gutiérrez, Ciro Semprebon, Glen McHale +1
We present a theoretical study of the statics and dynamics of a partially wetting liquid droplet, of equilibrium contact angle , confined in a solid wedge geometry of op…
Apparent Contact Angle and Contact Angle Hysteresis on Liquid Infused Surfaces
Ciro Semprebon, Glen McHale, Halim Kusumaatmaja
We theoretically investigate the apparent contact angle and contact angle hysteresis of a droplet placed on a liquid infused surface. We show that the apparent contact angle is not…
Deviation of viscous drops at chemical steps
Ciro Semprebon, Silvia Varagnolo, Daniele Filippi +4
We present systematic wetting experiments and numerical simulations of gravity driven liquid drops sliding on a plane substrate decorated with a linear chemical step. Surprisingly,…
Liquid morphologies and capillary forces between three spherical beads
Ciro Semprebon, Mario Scheel, Stephan Herminghaus +2
Equilibrium shapes of coalesced pendular bridges in a static assembly of spherical beads are computed by numerical minimization of the interfacial energy. Our present study focuses…
Ternary Free Energy Lattice Boltzmann Model with Tunable Surface Tensions and Contact Angles
Ciro Semprebon, Timm Krüger, Halim Kusumaatmaja
We present a new ternary free energy lattice Boltzmann model. The distinguishing feature of our model is that we are able to analytically derive and independently vary all fluid-fl…
The Role of Contact Angle Hysteresis for Fluid Transport in Wet Granular Matter
Roman Mani, Ciro Semprebon, Dirk Kadau +3
The stability of sand castles is determined by the structure of wet granulates. Experimental data about the size distribution of fluid pockets are ambiguous about their origin. We…
Filling transitions on rough surfaces: inadequacy of Gaussian surface models
Renaud Dufour, Ciro Semprebon, Stephan Herminghaus
We present numerical studies of wetting on various topographic substrates, including random topographies. We find good agreement with recent predictions based on an analytical inte…
