This Volume is the Proceedings of the IUTAM Symposium on Unsteady Separated Flows and Their Control held in Corfu, Greece, 18-22 June 2007. This was the second IUTAM Symposium on this subject, following the symposium in Toulouse, in April 2002. The Symposium consisted of single plenary sessions with invited lectures, - lected oral presentations, discussions on special topics and posters. The complete set of papers was provided to all participants at the meeting. The thematic sessions of this Symposium are presented in the following: Experimental techniques for the unsteady ow separation Theoretical aspects and analytical approaches of ow separation Instability and transition Compressibility effects related to unsteady separation Statistical and hybrid turbulence modelling for unsteady separated ows Direct and Large-Eddy Simulation of unsteady separated ows Theoretical/industrial aspects of unsteady separated ow control This IUTAM Symposium concerned an important domain of Theoretical and Applied Mechanics nowadays. It focused on the problem of ow separation and of its control. It achieved a uni ed approach regrouping the knowledge provided from theoretical, experimental, numerical simulation and modelling aspects for unsteady separated ows (incompressible and compressible regimes) and included ef cient control devices to achieve attenuation or suppression of separation. The subject - eas covered important themes in the domain of fundamental research as well as in the domain of applications.
Unsteady separated flows are an important topic in theoretical and applied mechanics. The IUTAM Symposium held in Corfu in 2007 (and following on from a previous meeting in Toulouse in 2002) aimed at achieving a unified approach which will regroup the knowledge coming from theoretical, experimental, numerical simulation, modeling and flow-control aspects of separated unsteady flows with respect to incompressible and compressible flow regimes.
Topics addressed include physical aspects of the dynamics related to unsteady separation in incompressible flows and flows under compressibility effects, and the state of the art methods for modeling these kinds of flows in high Reynolds numbers. Special attention is paid to control theory and applications, especially including feed-back effects for the attenuation of unsteadiness and of flow separation. The understanding of the flow-physics and their efficient turbulence modeling remains a serious problem in a number of engineering applications, including Aeronautics and Aeroelasticity. Furthermore, the study of advanced flow modeling techniques, especially to control high-Reynolds number transitional and turbulent flows involving unsteady separation, is a crucial need in the above-mentioned domains of fundamental and applied research nowadays.
