A vortex dynamics calculation of a turbulent jet has been used to study the behavior of discrete particles in an unsteady shear flow. Both axisymmetic and three-dimensional calculations have been performed. It was found that the three-dimensional code did not show significantly different behavior in terms of azimuthal particle disperion from the axisymmetric code under the thin vortex assumption. The full equation for particle dynamics was integrated through the flow field and the results were compared to a calculation which used only the drag force. It was found that the dispersion of droplets was underestimated typically by 25% by the simple approximation, with the greatest errors incurred for large droplets under high-pressure combustor conditions.
