|Flow separation determines the quality of environmental and biological flows alike. Large-scale separation on lifting surfaces, such as aircraft wings and wind-turbine blades, is a phenomenon of key technological significance, since it determines the performance characteristics of the surfaces involved. In addition, flow separation is a major contributor to aerodynamic noise generation. Analysis, computation and experimentation may all be used to identify physical mechanisms related with both hydrodynamic and aeroacoustic small-amplitude instabilities related with flow separation. Such linear perturbations may then be exploited in the context of theoretcally-founded (active or passive) flow control at a rather small energy imput. Of equal significance is the noise-reduction possibilities offered by precise knowledge of the noise generation mechanisms. The proposed action brings together leading scientists in the fields of theoretical, computational and experimental fluid mechanics, whose past work has made substantial contribution to the present understanding of separated flow instability and flow control. The respective groups have access to world-class computational or experimental facilities and an interest in pursuing a coordinated effort in a jointly-defined common direction. The consortium comprises nine PIs and their respective groups from five nations: 2 EU MCs (2), Brazil (2) an India (3). The capacities of the EU partners are predominantly theoretical/computational, while the non-EU groups have demonstrated strengths in both computation and experiment. In the course of the present action, short-duratio visits of seniors personnel as well as longer-term stays of junior researchers have been planned, with a twofold aim: knowledge-sharing and experience interchange amongst the senior personnel, as well as broadening of career perspectives through acquisition of new skills by younger researchers.
