Sweeping by Sessile Drop Coalescence
Jonathan M. Ludwicki, Paul H. Steen
During coalescence of liquid drops contacting a solid, the liquid sweeps wetted and solid-projected areas. The extent of sweeping dictates the performance of devices such as self-c…

The winner takes all: Volume-scavenging populations of networked droplets
Thomas C. Hagen, Paul H. Steen
In this work we present and analyze a fluid-mechanical model of competition (scavenging) amongst liquid droplets (individual competitors). The eventual outcome of this competit…

Dynamics of sessile drops. Part 3. Theory of forced oscillations
Joshua B. Bostwick, Paul H. Steen
A partially-wetting sessile drop is driven by a sinusoidal pressure field that produces capillary waves on the liquid/gas interface. The analysis presented in Part 1 of this series…
