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…
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…
Modal Analysis of Fluid Flows: Applications and Outlook
Kunihiko Taira, Maziar S. Hemati, Steven L. Brunton +5
We present applications of modal analysis techniques to study, model, and control canonical aerodynamic flows. To illustrate how modal analysis techniques can provide physical insi…
