N1 - Funding Information:
This work was supported by NASA Lewis Research Center through Grant NSG 3266 with P. Sockol acting as the Grant Monitor. The authors acknowledge U. R. Muller for providing the data for the pressure-driven, three-dimensional boundary layer and O. L. Anderson and V. N. Vatsa for making available the foundation code, which was modified extensively in this program. Part of the turbulence modeling effort was carried out by B. Lakshminarayana during his sabbatical at The Institute for Fluid Mechanics, Ecole Cen-trale de Lyon, where he was a visiting professor supported partially by Centre National De La Recherche Scientifique, Ministere de L'Educational Nationale and the U.S. National Science Foundation (Grant INT-87-02083, U.S.-Industrialized Countries Program for the exchange of Scientists and Engineers).

N2 - A method is developed for predicting the behavior of three-dimensional, turbulent boundary layers occurring in internal flows, including those on turbomachinery rotor blades. These boundary layers are complex, turbulent, and subject to Coriolis and centrifugal forces. The major thrust of this paper is the development and use of an algebraic Reynolds stress model (ARSM) that captures the changes in turbulent flow structure arising from curvature, rotation, and three dimensionality. The prediction of pressure-driven secondary flow agrees well with the measured data, and all three turbulence models (k-∈, algebraic eddy viscosity, and ARSM) show the same level of agreement. The prediction of boundary-layer development on rotor blades shows much better agreement with measurements with the ARSM. It is essential to employ higher-order turbulence models to capture the effects of rotation, curvature, and three dimensionality on boundary layers in turbomachinery.
