Steady State Shear Driven Flow of Frictionless Spherocylindrical~Particles in Two Dimensions

ORAL

Abstract

We carry out~simulations of a model of frictionless spherocylindrical rods in two dimensions,~under~uniform steady state shear driven flow.~~Rods repel elastically when they come into contact, and~dissipate~energy with respect to a uniformly sheared host medium. We pay~particular attention to the tumbling~motion of the rods that is induced by the~shear flow, computing the average angular velocity, and the~nematic and~tetratic orientational order parameters.~~We find non-monotonic behavior of the orientational~order parameters as~the packing fraction increases toward the jamming transition.~~Orientational and~translational~correlation functions are computed to measure cooperative behavior as the~packing fraction~increases.
