PARTICLE LAGRANGIAN SIMULATION IN TURBULENT FLOWS

Résumé

A Lagrangian approach is used to describe particle dispersion in turbulent flows. Fluid particle trajectories are simulated with the aid of a correlation matrix evolving along the particle trajectory. Discrete particles are tracked in a given turbulent field taking into account crossing-trajectory effects, and the influence of the particles on the flow characteristics is deduced from momentum and energy exchanges between both phases. Comparisons of the simulations are given for both experimental and theoretical results for fluid particle diffusion problems
