Measurements in the Boundary Layer of a Yawed Wing

Abstract

Measurements of the velocity profiles in the turbulent boundary layer on the upper surface of a wing of semielliptical plan form at an angle of yaw of 25 deg and angles of attack of 12 deg and 14 deg are reported along with pressure distributions. These show considerable spanwise flow near the surface. The chordwise (velocity components inclined 25 deg to the main wind direction) and spanwise boundary layers were calculated. The chordwise velocity profiles are in good agreement with those obtained at the National Bureau of Standards on an unyawed airfoil shape.
