The 3-D LDV measurements on a 30-degree swept wing with a simulated ice accretion

摘要

Three dimensional flowfield measurements have been obtained for a semispan 30-degree swept wing with a simulated glaze ice accretion. The model tested has a NACA 0012 section perpendicular to the leading edge. Measurements were made using a two-component laser Doppler velocimeter (LDV) system. Mean velocity measurements were obtained for all three velocity components. Streamwise turbulence intensities were also obtained. All measurements were taken in the University of Illinois 3 by 4 foot subsonic wind tunnel at a Reynolds number of 1 million and 8 degrees angle of attack. The data is presented in tabular form.
