A root vortex forms at the junction of a flat plate and an appendage, creating a three-dimensional separated flow. Time dependent oil film and oil dot visualizations of this turbulent flow have revealed the vortex system and have provided quantitative information on the direction and the magnitude of the shear stress. Two-dimensional LDV Laser Doppler Velocimetry mean velocity measurements were made in the separated flow region around the leading edge of the appendage, and these measurements are compared here with the flow visualization results.
