Phase Reduction Analysis of Transonic Buffet
Michael Candon, Earl Dowell
This paper develops a phase-reduced description of transonic buffet, treating buffet as a stable autonomous fluid limit cycle that is weakly perturbed by harmonic structural motion…
Neural Differential Equations for Oscillatory Flows in Aeroelasticity Applied to Transonic Buffet
Michael Candon, Pier Marzocca, Earl Dowell
Self-excited aerodynamic flows arise across a broad range of systems and can drive nonlinear fluid-structure interactions and aeroelastic instabilities that are challenging and com…
Aeroelastic Reduced-Order Model Differential Equations in Transonic Buffeting Flow
Michael Candon, Pier Marzocca, Earl H. Dowell
Numerical simulation of the transonic shock buffet phenomenon remains a formidable challenge due to its inherent nonlinear and unsteady characteristics. These difficulties are furt…
A Numerical Investigation of the Aeroelastic Interaction between Transonic Buffet and Structural Nonlinearity
Michael Candon, Vincenzo Muscarello, Pier Marzocca +1
Transonic shock buffet is a nonlinear, unsteady aerodynamic phenomenon characterized by self-sustained, periodic shock oscillations that can critically affect aircraft structural i…
