A STUDY OF SHEAR LAYER SUB-STRUCTURES IN LEADING EDGE VORTICES USING LASER DOPPLER VELOCIMETRY

Keywords: shear layer, sub-structures, lda, leading edge vortices

LDV measurements were taken of leading edge vortices about a flat plate delta wing. Periodic and stationary instabilities within the shear layer have been reported elsewhere. This study seeks to quantify the characteristics of these as a function of leading edge sweep, angle of attack, and chord-wise position and to aid understanding of the flow physics.
