Abstract
A direct simulation (DS) by Spalart of a three-dimensional turbulent boundary layer created by a rotating free-stream velocity vector offers a standard test case for turbulence models. The flow situation is calculated here using a second-moment closure applicable up to a wall, which was previously shown to reproduce various two-dimensional flows. The numerical solutions are extensively compared with the DS results including the distributions of all the Reynolds stress components. The agreement is generally satisfactory, showing the wide applicability of the turbulence model. The rather close alignment of the Reynolds stresses with the mean shear in the flow suggests a need for a separate test on more strongly three-dimensional boundary layers.
