摘要

Recent contributions to the 3-D vortex method for bluff-body flows are presented. The numerical method - a vortex method combined with a boundary element method - is briefy reviewed. It is applied to direct numerical simulation (DNS) of the flow past a sphere (Re = 300, 500 and 1000). The on-going work to extend the method towards vortex-based large-eddy simulation (LES) for high Reynolds number flows is also presented. Preliminary results for the flow past a hemisphere are discussed.
