Active flow control for drag reduction of vehicles using large eddy simulation, experimental investigations and reduced-order modeling
Paper i proceeding, 2013

The purpose of this short paper is to introduce first results obtained in a collaborative research between the partners. This research is dedicated to drag reduction of vehicles using LES, experimental investigation and ultimately reduced order modeling. First numerical and experimental results are presented. Experiments show that periodic forcing at high frequencies and amplitudes of the order of the upstream velocities can be viewed as a promising strategy for drag reduction targeted control of three-dimensional bluff-bodies.
