Alignment of a flexible platelike particle in shear flow: Effect of surface slip and edges

Rigid plate-like particles displaying interfacial slip can attain a constant orientation in shear flow when the length is sufficiently large. But actual thin such as single-layer graphene are prone to bending deformations exposed stress. To study effect of deformation on particle's stable orientation, we develop two-dimensional fluid-structure interaction model. We find that (i) alignment occurs even for relatively flexible particles, and (ii) edges effects shape plate important values length-to-thickness aspect ratio large 100.
