Shear-induced droplet mobility within porous surfaces
Si Suo, Haibo Zhao, Shervin Bagheri +2
Droplet mobility under shear flows is important in a wide range of engineering applications, e.g., fog collection, and self-cleaning surfaces. For structured surfaces to achieve su…
Roughness on liquid-infused surfaces induced by capillary waves
Johan Sundin, Stéphane Zaleski, Shervin Bagheri
Liquid-infused surfaces (LIS) are a promising technique for reducing friction, fouling and icing in both laminar and turbulent flows. Previous work has demonstrated that these surf…
Steady moving contact line of water over a no-slip substrate
Uǧis Lācis, Petter Johansson, Tomas Fullana +4
The movement of the triple contact line plays a crucial role in many applications such as ink-jet printing, liquid coating and drainage (imbibition) in porous media. To design accu…
Lift induced by slip inhomogeneities in lubricated contacts
Aidan Rinehart, Uǧis L{ā}cis, Thomas Salez +1
Lubrication forces depend to a high degree on elasticity, texture, charge, chemistry, and temperature of the interacting surfaces. Therefore, by appropriately designing surface pro…
Droplet leaping governs microstructured surface wetting
Susumu Yada, Shervin Bagheri, Jonas Hansson +4
Microstructured surfaces that control the direction of liquid transport are not only ubiquitous in nature, but they are also central to technological processes such as fog/water ha…
Higher order homogenized boundary conditions for flows over rough and porous surfaces
Y. Sudhakar, Ugis Lacis, Simon Pasche +1
We derive a homogenized macroscopic model for fluid flows over ordered homogeneous porous surfaces. The unconfined free-flow is described by the Navier-Stokes equation, and the Dar…
