Tumbling Motion of Interacting U-Shaped Particles in a Uniform Shear Flow Near Jamming

ORAL

Abstract

We simulate a system of overdamped frictionless U-shaped particles (staples) in a uniformly sheared host fluid. An isolated staple in such a shear flow undergoes a tumbling motion due to its asymmetric shape, with average angular velocity proportional to the shear strain rate. We investigate how this tumbling motion is modified in a dense system of interacting staples as we approach the jamming transition.
