The turbulent dispersion of particles in an unsteady 2-D particle-laden jet was simulated by a discrete vortex method coupled with a model of gas/particle interaction. A grid system was used to calculate the change in the circulation of the cell, which is caused by drag force on particles in a cell. The change of circulation in a cell was shared by vortices in a cell, and then the circulation of each vortex was corrected. Numerical analysis of a particle-laden jet yielded the distributions of vorticity, fuel concentration and local Sauter mean diameter. These distributions indicated that large particles are centrifuged to the periphery of the spray resulting in an increase of local mean diameter of particles in the peripheral region of the spray.
