Inertial torque on a small spheroid in a stationary uniform flow
F. Jiang, L. Zhao, H. I. Andersson +3
How anisotropic particles rotate and orient in a flow depends on the hydrodynamic torque they experience. Here we compute the torque acting on a small spheroid in a uniform flow by…

Theory for the effect of fluid inertia on the orientation of a small particle settling in turbulence
K. Gustavsson, M. Z. Sheikh, D. Lopez +3
Ice crystals settling through a turbulent cloud are rotated by turbulent velocity gradients. In the same way, turbulence affects the orientation of aggregates of organic matter set…
