Summary

This paper concerns the study of the three-dimensional interaction of a slat wake and a wing boundary layer, as commonly occurs on the suction surface of a high-lift rnulti-element aerofoil. The experimental test case has a realistic slat-wing flow configuration under infinite swept wing conditions. This enables the effect of the cross flow induced by the wing sweep on the slat wake and the wing boundary layer interaction process to be investigated. A triple hot-wire system has been used to measure the mean velocity and Reynolds stress components in the flow field. The measurements are used to validate a three-dimensional boundary layer code, which has been modified to calculate this three-dimensional wake-boundary layer mixing flow.
