Abstract
After decades of experimental and numerical research, the structure of turbulent boundary layers is only partially understood. Various organised motions have been identified as wall low-speed streaks, internal shear layers, vortical structures and ejections and sweeps [1]. Recent analysis of data bases from turbulence numerical simulation are giving important new insights about the spatial and temporal character of organised motions, their spatial relationships and their generation and evolution [2,3,4]. Numerical solutions are currently limited to simple geometries and low Reynolds number flows. Experimental investigation is still essential for flows with complex boundary conditions and high Reynolds numbers. Advanced experimental methods are becoming available to accomplish this task, most of them based on optical anemometry techniques.
