Experimental study of coherent structures in a turbulent boundary layer using PIV

Abstract : Particle Image Velocimetry experiments have been performed in a turbulent boundary layer wind tunnel in order to study the coherent structures taking par in the generation and preservation of wall turbulence. The particular wind tunnel used is well suited for high resolution experiments (δ > 0.3 m) at high Reynolds numbers (up to Rθ = 19 000 in the present results). The Particle Image Velocimetry experiments were carried out with different light sheet configurations including those similar to the visualization study by Head & Bandyopadhyay (1981). Eddy structures and near wall streaks were identified in instantaneous velocity maps in order to determine their mean characteristics.
