Interaction of two particles in a shear flow.
Our experimental study investigates the interaction of pairs of nearly spherical solid particles suspended in a stratified shear flow inside a Couette cell. The surfaces of the particles are well characterized, with roughness maps produced by a scanning electron microscope. We measure the degree of irreversibility introduced into the flow by particle interactions and relate it to the subtle differences in the particle surface features.
