Abstract: | This thesis concerns the angular motion of small particles suspended in fluid flows. A small particle experiences a hydrodynamic torque due to the local fluid velocity, and this torque leads to rotational motion. When inertial effects are negligible the torque on an ellipsoidal particle is given by Jeffery's theory [Jeffery, G. B. Proc. R. Soc. Lond. A 102, 161–179 (1922)]. In this thesis and the appended papers I describe three studies that all relate to this well-known result. First, we d... more |
