IUTAM Symposium on Mechanics of Passive and Active Flow Control

The call for papers for the rUTAM-Symposium on Mechanics of Passive and Active Flow Control brought an overwhelming response of applications for contributions. Fi­ nally 12 invited lectures, 48 papers and 23 posters were selected by thc Scientific Com­ mittee to be presented in the conference. 58 papers are published in this volume. Due to the limited number of pages available, poster presentations could not be considered for publication. The editors would like to thank all the members of the Scientific Committee for their very valuable assistance. The papers presented at the rUT AM Symposium were classified under three groups de­ voted to Passive Control Methods, Active Control Methods and Control Concepts. This was done to contrast at first between the passive techniques where the control power is mainly supplied by the flow itself and the active techniques where the power is pro­ vided by external sources; the third group was devoted to control concepts for presenting methods of control theory and new techniques of flow control.
