An unsteady dual analysis of self-excited instabilities and flow interactions, exemplified by a simple model compressor stage under subsonic conditions, is proposed and presented. Using a low-dissipation sliding-plane implementation, instability-resolving nonlinear-adjoint looping simulations provide detailed sensitivity information that allows for the dissection of the full flow into sub-components linked to distinct flow phenomena. This sensitivity information further links observed flow behaviour to its hydrodynamic or acoustic origin, thereby laying the foundation for a cause-and-effect analysis and for flow control.}, publisher = {Cambridge University Press}, keywords = {computational methods}, keywords = {nonlinear instability}, keywords = {aeroacoustics}, title = {Rotor-stator interactions in a model compressor stage: an unsteady dual analysis}, doi = {10.1017/JFM.2025.10338}, author = {Glazkov, Anton and Fosas de Pando, Miguel Ángel and Schmid, Peter}, }
