On a phase-shift of waves at the medium interface

Abstract: 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 … Show more

“…It should be noted that sequencing of the constrictions and expansions affects the oscillation amplitude in the gas-dynamic cavity between the LS and the rotor, and also increases the flow non-uniformity. Consequently, refusal to take these elements into account in aeroelastic calculation [15,[21][22] can give an additional margin from the point of view of reducing oscillations in LS, and, which is important for solving the related problems of continuum mechanics [19], reduce complexity and time of calculations.…”
