Abstract

The numerical prediction and study of turbulent two-phase flows using computational techniques such as Large Eddy Simulation (LES) that directly resolve the large, energy-containing scales of the turbulent motion was discussed. Within this broad class, the subset of two-phase flows in which a dispersed phase was comprised of small particles and was seen at low volume fractions was of primary interest, using Lagrangian computational techniques for the prediction of trajectories of a large ensemble of discrete particles. The advantages and limitations of such a technique were first considered and its accuracy was evaluated by comparison with discrete particle simulations coupled with fluid turbulence predictions obtained using DNS.
