A resolvent analysis framework for the axial compressor is established, and the impedance
optimization is achieved based on the resolvent analysis framework for the impedance …

Abstract The influence of Impedance Boundary Condition (IBC) on transonic compressors is
investigated. A systematic input-output analytical framework is developed, which treats the …

A wire mesh casing treatment is proposed and numerically tested on the transonic axial
compressor (Rotor 37). A theoretical stall inception prediction model was developed to …

The linear and nonlinear stability of two concentric jets separated by a duct wall is analysed
by means of global linear stability and weakly nonlinear analysis. Three governing …

Acoustic-hydrodynamic feedbacks are a common theme in jet noise. Strong sound
emissions are supported by fluid instabilities, whose core is not necessarily localized in …

Numerous current and future technological devices may benefit from the fundamental
understanding of the fluid instabilities leading to Vortex Induced Vibrations (VIV). Energy …

Acoustic-hydrodynamic feedbacks are a common theme in jet noise. Strong sound
emissions are supported by fluid instabilities, whose core is not necessarily localized in …

We present a summary of comprehensive results for the dynamics of the unconfined
(respectively, confined) laminar rounded compressible [2, 11, 12] impinging jet and the …
