SINOPSIS

A review of selected experiments on coherent structures in turbulent shear flow is performed. Different experimental approaches (conditional averages, filtering techniques, wavelets, Linear Stochastic Estimation and Proper Orthogonal Decomposition) are illustrated and their links with computations (LES, DNS, SDM,...) are emphasized. Particularly it is shown that some kind of universal behavior of the background turbulence can be retrieved from these various experimental methods.
