Capillary surfaces are fluid/fluid interfaces where surface tension strongly influences shape. Capillary surfaces include drops, bubbles, bridges, beads and rivulets. When a capillary surface meets a solid support, a wetting line forms.  Capillary surface and wetting line dynamics are important to a broad range of industrial and natural processes. Industrial examples includes semiconductor chip fabrication, 3D additive manufacturing, drop-on-demand and direct transfer printing processes, flow-shaping of hydrogels, and continuous casting of molten metals. This symposium will focus on progress and challenges to a predictive understanding of the dynamics of capillary surfaces and wetting lines.
