Harmonic methods are typically used to accelerate CFD simulations of unsteady-state rotor-stator interaction and blade flutter. In contrast to the mainstream unsteady-state applications, the presentation will illustrate a novel use of harmonic methods, namely to provide excellent steady-state rotor-stator interaction simulations.
It will be shown that using harmonic analysis for obtaining steady-state turbomachinery simulations is a viable alternative to the industry stalwarts of mixing plane or frozen rotor analysis. The presentation will provide a brief overview of harmonic analysis in the context of turbomachinery CFD simulations, and explore the topic of harmonic steady-state rotor-stator interaction.
