Electrophoretic molecular communication with time-varying electric fields

This article investigates a novel electrophoretic molecular communication mechanism that utilizes a time-varying electric field, which induces time-varying molecule velocities and in turn improves communication performance. For a sinusoidal field, we …

Substrate wettability affects mixing during droplet coalescence

73rd Annual APS DFD Meeting

Internal dynamics of coalescing droplets

Internal flows determine the extent of advective mixing (stretching and folding of fluid interfaces) between coalescing droplets, effectively defining the initial condition for molecular diffusion to homogenise the fluid. Efficient mixing is …

Substrate wettability influences internal jet formation and mixing during droplet coalescence

The internal dynamics during the axisymmetric coalescence of an initially static free droplet and a sessile droplet of the same fluid are studied using both laboratory experiments and numerical simulations. A high-speed camera captured internal flows …
