RÉSUMÉ

This contribution reviews the application of Direct Numerical Simulations (DNS) to the prediction of fluid-solid systems. First, the governing equations are presented and the numerical methods (fully explicit, Lagranian-Eulerian and explicit-implicit) discussed. The temporal and spatial discretization methods are described. Methods for moving the particles in the computational domain are presented and the influence of collisions is discussed. Finally, examples are given of the application of the code, including sedimentation of a single sphere in a tube, migration of neutrally buoyant sphere in a Poiseuille flow, interaction of particles in Newtonian and viscoelastic fluids and lubrication in pressure-driven particulate flows.
