Lectures: Four - One and half hour talks
(The first two are more historical reviews, the last two are current work.)
1 Particle tracking and equations of motion Review the Maxey-Riley equation for small particles in turbulence or unsteady flows, how this is extended to include finite Reynolds number effects, demonstration about added-mass at finite Reynolds numbers. Discuss spherical and nonspherical particles and how more complex passive particles can be tracked. (How important is the disturbance flow compared to the ambient flow.) 2 Particles in simple and turbulent flows Review motion of particles in cellular flow fields covering the range of heavy to buoyant particles showing how simple spatially varying flows can demonstrate processes seen elsewhere. Discuss spherical and nonspherical particles, chaotic tumbling and how inertia can regularize this. Importance of the divergence of the effective particle velocity field, challenges for exploring passive particle dynamics in high Reynolds number flows 3 Force-coupling method for particles in suspension Review methods of FCM, applications to finite Reynolds numbers, interacting particles, unsteady flows and suspensions of sedimenting particles, bidisperse suspensions or particles in a shear flow. How FCM provides a first step in representing flow modification at finite size. 4 Active particle suspensions Discuss magnetic beads in suspension, articificial micro-swimmers, micro-devices, blood flow as a suspension and the biological responses, bacterial motion and swimming (including bacteria found in seawater) |
