abstract
Droplet actuation and manipulation is currently a major area of research in digital microfluidics, which has vast applications in the biomedical, self-assembly, opto-fluidic, and materials fields. This project presents a new phenomenon in micro-scale droplet motion by taking advantage of asymmetric contact line hysteresis. A surface with angled stripes of different wetting properties is used to influence lateral motion of a falling drop. Designing lateral droplet motion may be used to improve de-wetting through the promotion droplet mixing, and may also provide an alternative approach to droplet actuation in “lab on chip” devices. Using the Lattice Boltzmann Method (LBM), simulations of a falling droplet on such a surface are being developed to test this phenomenon.
