Appropriate Turbulence Modelling for Turbomachinery Flows using a Two-Equation Turbulence Model.

The simulation quality of numerical flow simulations depends on the choice of physical modelling as well as an appropriate numerical treatment. In this study, a standard two-equation turbulence model has been extended for compressible, rotational flow as it occurs in turbomachinery and subsequently applied to different turbomachinery relevant flows of varying complexity. A number of different numerical schemes has been employed to evaluate their impact on the solution. [ABSTRACT FROM AUTHOR]
