Droplet impact on asymmetric hydrophobic microstructures
Susumu Yada, Ugis Lacis, Wouter van der Wijngaart +3
Textured hydrophobic surfaces that repel liquid droplets unidirectionally are found in nature such as butterfly wings and ryegrass leaves and are also essential in technological pr…
Nanoscale sheared droplet: Volume-of-Fluid, phase-field and no-slip molecular dynamics
Uǧis Lācis, Michele Pellegrino, Johan Sundin +4
The motion of the three-phase contact line between two immiscible fluids and a solid surface arises in a variety of wetting phenomena and technological applications. One challenge…
Near-wall turbulence alteration with the Transpiration-Resistance Model
Seyed Morteza Habibi Khorasani, Uǧis Lācis, Simon Pasche +2
A set of boundary conditions called the Transpiration-Resistance Model (TRM) are investigated in altering near-wall turbulence. The TRM has been previously proposed by \citet{Lacis…
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…
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…
A framework for computing effective boundary conditions at the interface between free fluid and a porous medium
Uǧis Lācis, Shervin Bagheri
Interfacial boundary conditions determined from empirical or ad-hoc models remain the standard approach to model fluid flows over porous media, even in situations where the topolog…
A stable fluid-structure-interaction solver for low-density rigid bodies using the immersed boundary projection method
Uǧis Lācis, Kunihiko Taira, Shervin Bagheri
Dispersion of low-density rigid particles with complex geometries is ubiquitous in both natural and industrial environments. We show that while explicit methods for coupling the in…
