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…
