Flow control and shape optimization
passive control : the idea is to put a porous interface between the solid body and the fluid. See the D. Depeyras thesis [68] and Yong-Liang Xiang [90] and CH Bruneau and Iraj Mortazavi) [55] . See also project [60] founded by the Euopean Community.
active control : see the three PhD thesis: M. Buffoni, J. Weller [87] , E. Lombardi and FFAST project funded by EU and iled by the University of Bristol and AIRBUS UK.
shape optimization for turbo-machines : See [84] .
reduced order models : it consists in designing a non-linear observer that estimates the state of the flow field from a limited number of measurements in the field. The challenge is to reduce as much as possible the information required and to take it from the boundary. See J. Weller [87] and E. Lombardi.
passive control of flows with porous media : see [57] , [54] , [53] , [78] , [58] .
inverse problems in imagery : see [62] .
