heal.abstract	A numerical algorithm based on the Lagrangian approach for the discrete phase and on the Eulerian for the continuous phase has been developed and used to predict a two-phase, droplet-laden swirling jet flow in a quarl geometry. The gas-phase equations are discretized using finite difference principles and are solved with the aid of the SIMPLE algorithm. The dispersion of the discrete phase is simulated using a stochastic separated flow model. After the reliability tests, the method is used to quantify the effects of droplet size, droplet loading, and swirl intensity on the carrier phase internal recirculation region and on the dispersion of droplets. The results indicate that the amount of recirculating mass increases with the droplet diameter and the decrease of loading. For high loading and swirl the internal recirculation region breaks down and it is divided into two subregions. Small droplets are dispersed following the gas phase, while large droplets are affected mainly by their injection conditions. © 1992.	en
