Prediction of turbulent flows is of paramount importance in a wide range of engineering applications. Vortex methods offer a fundamentally different means for modeling the effects of turbulence than conventional grid-based methods. By its close adherence to the essential dynamics of vortical structures in turbulence, its grid-free character and relatively small susceptibility to numerical diffusion, vortex methods may provide unique capabilities in predicting a wide spectrum of turbulent flows. In particular, they may be especially well suited for treating flows in complex geometries with moving boundaries, as well as in design studies where the effects of systematic variations in geometry need to be analyzed.
