Two Pronged Jet Formation Caused by Droplet Impact on Anisotropic Superhydrophobic SurfacesSource: Journal of Fluids Engineering:;2016:;volume( 138 ):;issue: 007::page 74501DOI: 10.1115/1.4032596Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a liquid droplet impacts a superhydrophobic surface with anisotropic surface patterning in the form of alternating ribs and cavities, the rebounding droplet may exhibit a unique twopronged jet emission. Droplet impact experiments with 11 different fluids of viscosity that varied by more than three orders of magnitude were conducted, and this paper quantifies the Capillary number, Ca, and Ohnesorge number, Oh, ranges over which the twopronged phenomenon occurs. For Oh > 0.0154, the behavior was never observed, while at lower values of Oh, the behavior occurs for an intermediate range of Ca that depends on Oh.
