On a wind tunnel model measurements have been made of the six components of the Reynolds stress tensor in a three-dimensional incompressible turbulent boundary layer under infinite swept wing conditions in an adverse pressure gradient, with a three-dimensional separation near the trailing edge. These measurements complement the mean velocity measurements that were carried out earlier in the same test set-up (NLR TR 72O92 U). The measurements were carried out with a rotatable X-wire probe. An extensive discussion of the errors involved in this type of measurement is given. Turbulence intensities and turbulent shear stresses have been measured From the mean velocity profiles the velocity gradient is derived azid compared with the shear stress magnitude and direction. An interpretation of the results is included.
