Low-Mach-number aeroacoustic theories are applied to predict far-field sound emission from vortex-dominated flows. The latter are simulated using three-dimensional vortex methods. Both particle schemes and filament-based schemes are used. Comparisons of model predictions with theoretical and experimental results on the interaction of two vortex rings are first discussed. Next, the schemes are used to examine the effect of initial conditions and 3D perturbations on the properties of the far-field acoustic pressure. Finally, a more elaborate wind-turbine model is presented and its application to the evaluation of several turbine-blade designs is summarized.
