The collapse transition on superhydrophobic surfaces
H. Kusumaatmaja, M. L. Blow, A. Dupuis +1
We investigate the transition between the Cassie-Baxter and Wenzel states of a slowly evaporating, micron-scale drop on a superhydrophobic surface. In two dimensions analytical res…
Coupling Lattice Boltzmann and Molecular Dynamics models for dense fluids
A. Dupuis, E. M. Kotsalis, P. Koumoutsakos
We propose a hybrid model, coupling Lattice Boltzmann and Molecular Dynamics models, for the simulation of dense fluids. Time and length scales are decoupled by using an iterative…
Rheology of cholesteric blue phases
A. Dupuis, D. Marenduzzo, E. Orlandini +1
Blue phases of cholesteric liquid crystals offer a spectacular example of naturally occurring disclination line networks. Here we numerically solve the hydrodynamic equations of mo…
Dynamics of sliding drops on superhydrophobic surfaces
A. Dupuis, J. M. Yeomans
We use a free energy lattice Boltzmann approach to investigate numerically the dynamics of drops moving across superhydrophobic surfaces. The surfaces comprise a regular array of p…
Drop dynamics on chemically patterned surfaces
H. Kusumaatmaja, J. Leopoldes, A. Dupuis +1
We compare numerical and experimental results exploring the behaviour of liquid drops moving across a surface patterned with hydrophobic and hydrophilic stripes. A lattice Boltzman…
Control of drop positioning using chemical patterning
A. Dupuis, J. Leopoldes, D. G. Bucknall +1
We explore how chemical patterning on surfaces can be used to control drop wetting. Both numerical and experimental results are presented to show how the dynamic pathway and equili…
Modelling droplets on superhydrophobic surfaces: equilibrium states and transitions
A. Dupuis, J. M. Yeomans
We present a lattice Boltzmann solution of the equations of motion describing the spreading of droplets on topologically patterned substrates. We apply it to model superhydrophobic…
Numerical calculations of the phase diagram of cubic blue phases in cholesteric liquid crystals
A. Dupuis, D. Marenduzzo, J. M. Yeomans
We study the static properties of cubic blue phases by numerically minimising the three-dimensional, Landau-de Gennes free energy for a cholesteric liquid crystal close to the isot…
Mesoscopic modelling of droplets on topologically patterned substrates
A. Dupuis, J. M. Yeomans
We present a lattice Boltzmann model to describe the spreading of droplets on topologically patterned substrates. We apply it to model superhydrophobic behaviour on surfaces covere…
Jetting Micron-Scale Droplets onto Chemically Heterogeneous Surfaces
J. Leopoldes, A. Dupuis, D. G. Bucknall +1
We report experiments investigating the behaviour of micron-scale fluid droplets jetted onto surfaces patterned with lyophobic and lyophilic stripes. The final droplet shape depend…
Droplet Spreading on Heterogeneous Surfaces using a Three-Dimensional Lattice Boltzmann Model
A. Dupuis, A. J. Briant, C. M. Pooley +1
We use a three-dimensional lattice Boltzmann model to investigate the spreading of mesoscale droplets on homogeneous and heterogeneous surfaces. On a homogeneous substrate the base…
