In this paper we present the results of the application of a Lagrangian particle dynamics (LPD) method and a random flow generation technique (RFG) developed by the authors used in conjunction with large eddy simulations (LES) applied to the case of a two-phase bubbly mixing layer. The objective is to validate the present hybrid Lagrangian-Eulerian approach within the context of LES. The dynamics of the vortices and bubble concentrations reproduced in simulations are in a good agreement with experimental data.Copyright © 2002 by ASME
