Orientation dynamics of weakly Brownian particles in periodic viscous flows
arXiv:physics/0507086 · doi:10.1103/PhysRevE.73.041406
Abstract
Evolution equations for the orientation distribution of axisymmetric particles in periodic flows are derived in the regime of small but non-zero Brownian rotations. The equations are based on a multiple time scale approach that allows fast computation of the relaxation processes leading to statistical equilibrium. The approach has been applied to the calculation of the effective viscosity of a thin disk suspension in gravity waves.
