Abstract:
Kirigami designs consist of a pattern of slits, or a combination of slits and creases, which makes them different from origami designs that are solely based on creases. The ease of production and deployment (which is often done simply by applying external tension on a 2D sheet) has caused several recent applications for kirigami sheets in ``structural mechanics, materials, optics, electronics, robotics, and bioengineering". Despite this extensive use in other fields, kirigami designs have not been used for fluid mechanic applications. Here, we discuss the potentials of kirigami sheets as passive flow control devices by considering the behavior of kirigami sheets placed perpendicular to an incoming flow and observing their response to the flow forces and their corresponding wakes.
