Symposium Nov. 2014
In 2011 the German Research Association (DFG) launched a research group on "Active Drag Reduction via Wavy Surface Oscillation" which combines scientists from the fields of control theory, fluid mechanics, metal forming, and electronics. The main long-term objective of this program is the development of a simple, yet energy efficient method to influence the turbulent boundary layer such that drag is minimized reduction by active or a combination of active and passive means. To satisfy this goal 7 projects have been defined in the different areas of control theory, fluid mechanics, metal forming and electronics. In each of these projects scientists collaborate in several experimental and numerical investigations to improve the fundamental knowledge of the underlying physical mechanisms of drag reduction, a possible control approach, and the feasibility in terms of manufacturing such an actuated system.
