Euler solutions of flow around a rectangular wing with square tip

Abstract

Low speed flows about a high-lift rectangular wing with square lateral tip are computed by a three-dimensional compressible Euler flow solver. Flow separation around the square tip of the wing is studied. The flow is, otherwise, attached to the surface of the wing. The pressure distributions over the upper and lower surfaces of the wing, especially on the outer portion of the wing and the generation and evolution of the tip vortices in the near field of the wing are computed by the Euler method and validated by a comprehensive wind-tunnel test data in the literature. The effects of the wind-tunnel wall are not considered in the computations.
