Title: Velocity fluctuations in dense sheared granular flows with internal imaging

Author (Poster): Arshad Kudrolli, Clark University

Abstract:

We will discuss experiments on dense granular flows sheared by a rough boundary with a fluorescent refractive index matched interstitial fluid technique. We will report on the effect of shear on the grain fluctuations and diffusion perpendicular and parallel to the shear plane. The results will be compared with previous results in the non-sheared and plug flow region inside a silo. In collaboration with Ashish Orpe.
