A detailed numerical study on the drag reduction effects of rear-edge periodic actuation on a flat-back 2.5D Ahmed body (a two-dimensional body extended in the third dimension) is presented, with particular focus on an optimum open-loop configuration. Actuation is applied simultaneously in both perpendicular and parallel directions from the upper and lower rear-edges, in phase. Large Eddy Simulations at Re = 23,000 show an optimum drag reduction range between St_{act} = 0.09 and St_{act} = 0.13. There is also a region St_{act} = 0.23-0.27, near the natural Strouhal number, which shows less efficient results. Both results agree with recent experiments completed by Pastoor (2008). A thorough transient wake analysis, including Dynamic Mode D...
