An Experimental Investigation of the Flow Past an Idealized Wing-Body Junction

Abstract

Velocity measurements, pressure measurements and surface oil-flow visualizations, performed in the flow past an idealized wing-body junction, are presented. The junction consists of a cylindrical wing mounted normal to a flat surface on which an otherwise two-dimensional turbulent boundary is growing. The velocity measurements were made over a detailed grid using hot-wires and a three-component laser Doppler anemometer. At most locations all components of mean velocity and the Reynolds stress tensor were measured. These data clearly reveal, for the first time, the turbulence structure of the horseshoe vortex and the surrounding flow. The purpose of this report is to present the data in a form suitable for use by other researchers, especially those wishing to compute this flow. Keywords: Wing body configurations; Turbulent boundary layer; Hotwire anemometers; Laser Doppler anemometers; Experimental data; Boundary layer flow; Three dimensional flow separation; Turbulence/flow visualization.
