Title: New experimental approaches for measuring and controlling fluid flows
Abstract: Multidisciplinary approaches can provide a unique experimental toolbox for resolving, understanding, and controlling fluid behavior. In this talk, I will present two such tools enabled by advancements in micro/nanoscale fabrication and describe how they can be applied to fundamental fluid mechanics research. The first investigation considers the behavior of a new family of surface modifications inspired by the Nepenthes pitcher plant and reveals a novel, passive method of turbulent drag reduction. Both experimental and numerical approaches are used to examine how these surfaces respond to and interact with turbulent shear flow. The second investigation describes a selective, strain-based velocimetry technique that utilizes the bending of a free-standing, electrically-conductive nanoribbon under fluid forcing. The sensor behavior is experimentally and theoretically characterized and found to be suitable for a wide range of applications, including turbulent flow measurements.
