Evaluation of the CFD-Methods elsA and TRACE by their application to Steady and Unsteady Turbine and Compressor Flows

Kurzfassung

The document describes a detailed benchmark of two CFD methods, the elsA and the TRACE code. Both methods were applied to typical turbomachinery problems, a transonic turbine stage and a subsonic, single-stage compressor. The code comparison includes steady state as well as unsteady computations. Apart from a detailed code-to-code comparison with respect to performance and aerodynamic results, comparisons with available steady and time resolved measurement data are presented and discussed.
