Jetting micron-scale droplets onto chemically heterogeneous surfaces by Leopoldes, J, Dupuis, A, Bucknall, D, Yeomans, J

“…We report experiments investigating the behavior of micron-scale fluid droplets jetted onto surfaces patterned with lyophobic and lyophilic stripes. …”

Mesoscopic modelling of droplets on topologically patterned substrates by Dupuis, A, Yeomans, J

“…We apply it to model superhydrophobic behaviour on surfaces covered by an array of micron-scale posts. We find that the patterning results in a substantial increase in contact angle, from 110degrees to 156degrees.…”

Lattice boltzmann simulations of wetting and drop dynamics by Kusumaatmaja, H, Yeomans, J

“…Recently there has been a huge effort in the scientific community to miniaturise fluidic operations to micron and nanoscales [1]. This has changed the way scientists think about fluids, and it potentially has far-reaching technological implications, analogous to the miniaturization of electronics. …”

Droplet dynamics on patterned substrates by Dupuis, A, Yeomans, J

“…We also consider a substrate covered with micron-scale posts and investigate how this can lead to superhydrophobic behaviour. …”

Droplet dynamics on patterned substrates by Dupuis, A, Yeomans, J

“…We also consider a substrate covered with micron-scale posts and investigate how this can lead to superhydrophobic behaviour. …”

Drop dynamics on hydrophobic and superhydrophobic surfaces. by Mognetti, B, Kusumaatmaja, H, Yeomans, J

“…We investigate the dynamics of micron-scale drops pushed across a hydrophobic or superhydrophobic surface. …”

Drop dynamics on chemically patterned surfaces by Kusumaatmaja, H, Leopoldes, J, Dupuis, A, Yeomans, J

“…When compared, the numerical results agree well with experiments on micron-scale drops moving across substrates patterned by microcontact printing. © EDP Sciences.…”

The collapse transition on superhydrophobic surfaces by Kusumaatmaja, H, Blow, M, Dupuis, A, Yeomans, J

“…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 results show that there are two collapse mechanisms. …”

Generic Behaviour of Model UV Cure Ink-Media Interactions by Léopoldès, J, Wilkins, S, Bucknall, D, Dupuis, A, Yeomans, J

“…Using Lattice Boltzmann simulations of droplet spreading, we show that the location of the impact point of a droplet on patterned substrate with micron size chemical heterogeneity is an important criterion to consider with respect to the equilibrium shape of a droplet. …”

Behaviour of ink droplet media interactions in model systems by Bucknall, A, Dupuis, A, Leopoldes, J, Wilkins, S, Yeomans, J, Is, T

“…Using Lattice Boltzmann simulations of droplet spreading, we show that the location of the impact point of a droplet on patterned substrate with micron size chemical heterogeneity is an important criterion to consider with respect to the equilibrium shape of a droplet. …”

Modeling microscopic swimmers at low Reynolds number. by Earl, D, Pooley, C, Ryder, J, Bredberg, I, Yeomans, J

“…Using multiparticle collision dynamics the authors show that a driven filament behaves in a qualitatively similar way to the micron-scale swimming device recently demonstrated by Dreyfus et al. …”
