Improved convergence of the spectral proper orthogonal decomposition through time shifting
Diego C. P. Blanco, Eduardo Martini, Kenzo Sasaki +1
Spectral proper orthogonal decomposition (SPOD) is an increasingly popular modal analysis method in the field of fluid dynamics due to its specific properties: a linear system forc…
On the Low-Frequency Dynamics of Turbulent Separation Bubbles
C. Cura, A. Hanifi, A. V. G. Cavalieri +1
The low-frequency modal and non-modal stability characteristics of an incompressible, pressure-gradient-induced turbulent separation bubble (TSB) are investigated with the objectiv…
Stability and Order of Accuracy Analysis of High-Order Schemes Formulated Using the Flux Reconstruction Approach
Frederico Bolsoni Oliveira, João Luiz F. Azevedo
A stability analysis is performed on high-order schemes formulated using the Flux Reconstruction (FR) approach. The one-dimensional advection model equation is used for the assessm…
Aeroelastic Analysis of Transonic Flutter with CFD-Based Reduced-Order Model
Ana Cristina Neves Carloni, João Luiz F. Azevedo
The current work is concerned with studying processes for constructing reduced-order models capable of performing transonic aeroelastic stability analyses in the frequency domain b…
Development of Transonic Unsteady Aerodynamic Reduced-Order Models Using System Identification Techniques
Ana Cristina Neves Carloni, João Luiz F. Azevedo
The present paper develops a reduced-order model capable of modeling unsteady aerodynamic loads in the transonic regime using system identification techniques. The computational fl…
Multi-scale invariant solutions in plane Couette flow: a reduced-order model approach
Matthew McCormack, André V. G. Cavalieri, Yongyun Hwang
Plane Couette flow at Re=1200 (based on the channel half-height and half the velocity difference between the top and bottom plates) is investigated with a spatial domain designed t…
