A LAGRANGIAN APPROACH FOR THE PREDICTION OF PARTICLE DISPERSION IN TURBULENT FLOWS

A first computer code (DISCO) has been developed during the past years for predicting turbulence fields and the dispersion of discrete particles in the framework of an Eulerian approach. Although that approach can be used for several engineering situations, the assumptions of the underlying theories prevent new developments of the code from handling complex situations. A new method, based on a Lagrangian approach previously studied by A. Ormancey and J. Martinon has been developed, and is briefly described in this paper.
