In this article we overview interdisciplinary problems and perform the numerical modeling of a two-way fluid–structure interaction (2FSI) of processes in a gas-rotor-stator system in relation to a prototype compressor stage. Physical, solid-state and mesh-based models are developed. By calculating the 2FSI, we evaluate the interference of a gas-dynamic stream and a deformable rotor blade. The obtained results are discussed. An important finding of the numerical experiment is that a phase-shift of oscillations between the static and dynamic pressure components in optically transparent environment and a phase shift of pressure oscillations in an optically transparent medium and movement in an optically opaque medium are discovered.

interdisciplinary calculation, experimental compressor stage, phase-shift, optical medium.
