Final Report Summary - ICOMASEF (Instability and COntrol of MAssively SEparated Flows)
The International Research Scientists Exchange Scheme (IRSES) scheme was an instrument in support of international collaboration within the Framework 7 EU Marie Curie program. Under the IRSES scheme research interests of scientists from EU and non-EU organizations participating in the consortium were organized in work-packages and executed through travel grants (so-called secondments) supported by the EU, while the core research funding had been put in place in advance by the participating organizations. Travel support was provided for Experienced Researchers (ERs), typically faculty and senior staff members, and Early Stage Researchers (ESRs), typically Ph.D. students and early-career post-doctoral researchers, in order to visit members of the consortium other than their own, for a period of up to 12 months per person, thus broadening the scope of work pursued at the home institution.
The Instability and Control of Massively Separated Flows (ICOMASEF) IRSES Grant, was coordinated by the author and was organized around the joint research interests of the groups led by Vassilis Theofilis (Universidad Politécnica de Madrid, Spain), Spencer Sherwin (Imperial College London, UK), Julio Soria and Hugh Blackburn (Monash University, Australia), Marcello de Medeiros and Julio Meneghini (Universidade São Paulo, Brasil), Rama Govindarajan (then at Jawaharlal Center for Advanced Scientific Research, India) and O.N. Ramesh (Indian Institute of Science, India) and a total of 32 researchers from the consortium members, who performed 120 months of secondments between January 1, 2011 and December 31, 2014. Progress was monitored through four annual review meetings, held at the Monash Center in Prato, Italy in July 2011, in parallel to the 5th Global Flow Instability and Control Symposium in Crete, Greece in September 2012, again in Prato in September 2013, this time in conjunction with an international conference on a topic synonymous with the IRSES project, and finally immediately after the 8th IUTAM Laminar-Turbulent Transition Symposium in Rio de Janeiro, Brasil in September 2014. Six new international grants jointly submitted by ICOMASEF partners were won, two joint Ph.D. degrees were awarded, while some 30 joint publications and an equal number of international conference contributions were generated by consortium members during the lifetime of the project; more activity is expected in the immediate future. In the following, a brief description of concrete results obtained in the framework of the project is presented, alongside the related publications.

The overall theme of the ICOMASEF project was to combine the predominantly theoretical/numerical capabilities available to the EU side with state-of-the-art computational and experimental capabilities available to the overseas partners, with the aim of furthering understanding of separated flow, its instability and control. Researchers working primarily on theory were exposed to and gained experience from the experimental facilities of partner organizations, while experimentalists gained experience in flow instability analysis and high performance computing.
A series of developments was planned and has been successfully completed, including:
• Theoretical and numerical methods development for the computation of optimal inflow perturbations in separated flows.
• Development of the next-generation high-order computational tools for unsteady Computational Fluid Dynamics and instability analysis of incompressible separated flows.
• Development of algorithms necessary for the analysis of compressible separated flows and to model aeroacoustic behavior arising from separated flows such as undercarriages or wind turbines.
• Development of a simplified theoretical separated flow description, including results of local and global instability analysis and supported by experimentation.
• Experimental and theoretical study of instabilities in open cavity flows, including cavity acoustics.
• Analysis and control of vortex-induced vibrations
Details of the results obtained as well as the extensive list of publications which resulted from the ICOMASEF grant, can be found in the following sections.
Further information can be requested from the Coordinator, Prof. Vassilis Theofilis School of Aeronautics, UPM.
