Abstract
The objective of the research reported in this paper was to develop computational techniques for the prediction of transitional flows associated with the rotor-stator interaction in turbomachinery. Three lowReynolds-number turbulence models were incorporated in the Navier- Stokes code and evaluated for accuracy in predicting the onset and end of unsteady transitional patches caused by wake passing. The best model was then used for the modification and improvement of the leading-edge effect. A comparison with the experimental data indicated that the quality of prediction was as good as those derived from an unsteady boundary-layer code. A comparison of the instantaneous shape factor, the skin friction coefficient, and the momentum thickness indicated that the Navier-Stokes predictions were reasonably good and should aid the designers of turbomachiner y in allowing for the unsteady transitional flows caused by rotor-stator interaction. The simulation results were interpreted to derive new insight on the flow physics associated with transitional flow including turbulence properties.
