Experiment on turbulent boundary layers over a concave surface - Effects of introduction of curvature

The response to the introduction of streamwise concave surface curvature without substantial pressure gradient is discussed to obtain an adequate flow model. The detailed mean velocity and turbulence measurements were performed near the onset of curvature. The behavior of the effective curvature is also reported. The effects of the step change in geometric curvature on the structure of mean flow and turbulence properties are examined.
