Application of the k-omega turbulence model to quasi-three-dimensional turbomachinery flows

In this study, an attempt is made to incorporate the low Reynolds number k-ω model in the quasi-three-dimensional turbomachinery analysis code. The k-ω model was implemented using many of Menter's recommendations and an implicit approximate-factorization scheme. The model was tested for a transonic compressor with rotation and variable stream-surface radius and height, and for a transonic turbine vane with transition and heat transfer. Results were compared to the B-L model and to experimental data.
