“…Detailed comparisons presented in Anderson & Eaton (1987) show that the data a t station 5 compare well with the data of Dechow & Felsch (1977) and plots. Muller (1982). Both of these flows are 'obstacle-type' flows where the initially twodimensional boundary layer is deflected sideways by an obstacle.…”

“…Experiments in somewhat more complicated geomet,ries have arrived at different conclusions. For example, Ezekwe Pierce & McAllister (1978), Fernholz & Vagt (1981), and Muller (1982) have all observed a lead in the shear stress vector ahead of the strain rate. Fernholz & Vagt (1981) concluded that this was caused by very rapid distortions of the turbulence.…”

The development of the Reynolds stress field was studied for flows in which an initially two-dimensional boundary layer was skewed sideways by a spanwise pressure gradient ahead of an upstream-facing wedge. Two different wedges were used, providing a variation in the boundary-layer skewing. Measurements of all components of the Reynolds stress tensor and all ten triple products were measured using a rotatable cross-wire anemometer. The results show the expected lag of the shear stress vector behind the strain rate. Comparison of the two present experiments with previous data suggests that the lag can be estimated if the radius of curvature of the free-stream streamline is known. The magnitude of the shear stress vector in the plane of the wall is seen to decrease rapidly as the boundary-layer skewing increases. The amount of decrease is apparently related to the skewing angle between the wall and the free stream. The triple products evolve rapidly and profiles in the three-dimensional boundary layer are considerably different than two-dimensional profiles, leaving little hope for gradient transport models for the Reynolds stresses. The simplified model presented by Rotta (1979) performs reasonably well providing that an appropriate value of the T-parameter is chosen.

“…They measured only mean flow and wall shear stress, and noted that the mean velocity appeared to be turning all the way to the wall. Müller (1982) measured flow turned spanwise by vanes, in a geometry similar to the current experiment.…”

The three-dimensional flow in the blade end wall corner region was investigated. The techniques used in the investigation included flow visualization, static and total pressure measurements with conventional probes, and mean volocity profile measurements with a single sensor inclined hot-wire probe. Six critical axial stations along the blade chord were chosen for detailed measurements based on the flow visualization results. A large number of data points were obtained very close to the corner walls at each axial location including all the components of the mean velocity. Based on the measurements, three vortices were identified. A horseshoe vortex started near the leading edge. A corner eddy was formed between the horseshoe vortex and the corner. Another vortex was formed at the rear portion of the corner due to the secondary flow of the second kind. The relative size and the rate of spread of the vortices in the streamwise direction are discussed.
