Abstract
A time-linearized aeroelastic solver was developed and then modified to deal with incoming perturbations due to unsteady interactions with upstream/downstream rows, in order to investigate tone noise generation and propagation for aeroacoustic analysis. Such a three-dimensional method is presented, with special emphasis on three-dimensional non-reflecting boundary conditions, accounting for 3D radial modes on a sheared mean flow with swirl. Some test results are presented and compared with numerical data available in the literature.
