Title: Harnessing viscous streaming in complex active systems: mini-bots in fluids.
Abstract: Viscous streaming is a phenomenon where an oscillating body generates stable, predictable and robust fluid flows that can be used to manipulate the body’s local surroundings. Viscous streaming has been well explored and characterized theoretically, experimentally and computationally for simple shapes such as cylinders and spheres, and leveraged in microfluidics for transport, mixing, particle separation and assembly. However, little is known beyond simple geometries, in particular when multiple curvatures are involved. Here we explore the effects of body geometric variations on topological flow responses, and connect them with potential uses in micro-robotics.
