Abstract: Random vortex methods are Lagrangian particle-based numerical simulation schemes especially appropriate for Wind Engineering simulations. Vortex methods do not suffer from numerical diffusion and hence can model flows characterized by high Reynolds numbers. Their grid-free nature makes them also attractive for complex geometries where the adaptive mesh generation needed in grid-based simulations can be avoided. In this paper, we briefly describe random vortex methods and show some early results from a two dimensional implementation.
