A spherical drop is constrained by a solid support arranged as a latitudinal belt. The
spherical belt splits the drop into two deformable spherical caps. The edges of the belt …

A class of unsteady two-and three-dimensional velocity fields for which the associated stable
and unstable manifolds of the Lagrangian trajectories are explicitly known is introduced …

Two droplets coupled through a liquid filled (a) hole in a plate or (b) tube is referred to as a
double droplet system (DDS) or a capillary switch. Such capillary systems are gaining …

A double droplet system (DDS) consists of a sessile and a pendant drop that are coupled
through a liquid filled cylindrical hole in a plate of thickness d⁠. For a small hole radius R⁠ …

The response of steady state vortex flows in an enclosed circular cylinder driven by the
harmonic modulation of the rotating end wall is investigated experimentally and numerically …

The effect of the insertion of a bubble swarm in the separation of finely dispersed oil droplets
in a liquid flow was investigated experimentally. The generation of gas bubbles and oil …

A capillary switch is a bi-stable system of liquid/gas interfaces with a trigger to toggle back
and forth between the two stable equilibrium states. We use an electro-osmotic pump as …

Double droplet systems are comprised of two coupled spherical interfaces. These systems
are effective harmonic oscillators, due to their low dissipation and fast response; features …

A capillary switch is a system of two liquid drops, one sessile and the other pendant,
obtained by overfilling a hole of radius R in a plate. When surface tension dominates gravity …

Two inviscid coupled spherical-cap droplets oscillate. This paper considers a network of n
spherical-cap droplet oscillators coupled via a central reservoir such that the system has …
