Characterization of Transonic Aerodynamic Damping of Rockets Based on CFD/CSD Coupling
气体物理, 2023 With the development of new high-thrust rockets, the decreasing frequency of the bending modes of the rocket, as well as the factors such as flow separation and shock oscillations generated during transonic flight make it more prone to non-constant ...

Aerodynamic Damping of the Tubed Vortex Reducer in an Axial Compressor Disk Cavity
Aerospace, 2023 The tubed vortex reducer in the axial compressor can destroy the vortex in the disk cavity, by a thin-walled tube, to reduce the total pressure loss. The tube may suffer from vibration problems, such as flutter and forced vibration, which are closely ...

An analytical frequency‐domain model of aerodynamic mass and damping of floating wind turbines
Wind Energy, 2023 The fore‐aft motion of the rotor‐nacelle assembly (RNA) of a rotating floating wind turbine (FWT) can cause an oscillation in aerodynamic thrust, which may be equivalently treated as frequency‐dependent aerodynamic mass and damping effects. In this study,
