    "abstract": "Evolution equations for the orientation distribution of axisymmetric\nparticles in periodic flows are derived in the regime of small but non-zero\nBrownian rotations. The equations are based on a multiple time scale approach\nthat allows fast computation of the relaxation processes leading to statistical\nequilibrium. The approach has been applied to the calculation of the effective\nviscosity of a thin disk suspension in gravity waves.",
