Object: to provide a state of the art and accessible survey of numerical and experimental approaches as well as modelling tools for the analysis of collective dynamics of particles in flows.

The training school is organized with lectures and a workshop on day 2. The course will be organized under the auspices of ERCOFTAC SIG12 ``Dispersed Turbulent Two- Phase Flows'' and SIG43 ``Fiber suspension flow modelling'' and with the support of two COST Actions: Action FP1005 ``Fiber suspension flow modelling: a key for innovation and competitiveness in pulp and paper industry'' and ANR CoDSPiT "Collective dynamics of settling particles in turbulence".

Trainers and Topics:
Gilles Bouchet - Aix-Marseille University, France
4 Lectures on: General introduction to scope and content of the course. Transition scenario in the wake of spherical and anisotropic particles (spheroids, discs, cylinders, fibres). Transition scenario of the solid-fluid systems (free falling or rising bodies interacting with the ambient fluid via hydrodynamic forces).
Michael Bourgoin - University of Grenoble, CNRS, France
5 Lectures on: Collective effects of inertial particles in turbulent flows. Theoretical framework and phenomenology of particle-turbulence interactions. Experimental and numerical observations of preferential concentration. Analysis tools to diagnose preferential concentration and characterize clusters geometry. Open questions and ongoing researches.
Jason Butler - University of Florida, Gainesville, USA
5 Lectures on: Collective Stokesian dynamics of spherical particles and slender bodies suspended within viscous fluids. Governing equations and applications to sedimentation and shear flows.
John Hinch - University of Cambridge, UK 6 Lectures on: Small particles in highly viscous fluid; sedimentation and rheology. Low-Reynolds-number limit at the level of individual particles, small inertial correction. Sedimentation of one, few or many particles. Numerical issues. Rheology of a suspension: homogenization, rotations, deformations and interactions of particles.
Holger Homann -Observatoire de la Cote d'Azur, Nice, France
5 Lectures on: From point to finite-size particles: different physics, different numerical modeling. Details on the method of fictitious domains. Finite-size effects in the dynamics of individual particles. Collective effects of finite-size particles.
Martin Maxey - Brown University, Providence, USA
6 Lectures on: Numerical methods for modeling and simulation of rigid particles in fluid flow. Particle tracking equations with one-way or two-way coupling and their application. Approximate force coupling method (FCM) at low and finite Reynolds numbers. Immersed boundary methods, extensions to non-spherical particles and examples of applications in dispersed multiphase flows.
