Abstract
In this paper we calculate the shear-induced self and gradient diffusivities in a dilute bidisperse suspension of hard spheres. Unlike the interaction of identical spheres, the center of mass of a pair of unequally sized spheres does not translate with the imposed shear flow and hence the radial and tangential drifts of the center of mass were tracked using appropriately defined mobility functions. Results of the trajectory calculations show that the minimum surface-to-surface distance ξ
