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…
Modal-based generalised quasilinear approximations for turbulent plane Couette flow
Igor A. Maia, André V. G. Cavalieri
We study generalised quasilinear (GQL) approximations applied to turbulent plane Couette flow. The GQL framework is explored in conjunction with a Galerkin reduced-order model (ROM…
Widest scales in turbulent channels
Ramón Pozuelo, André V. G. Cavalieri, Philipp Schlatter +1
The widest spanwise scales in turbulent channel flows are studied through the use of three periodic channel-flow simulations at friction Reynolds number . The le…
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…
Modal decomposition of nonlinear interactions in wall turbulence
Ugur Karban, Eduardo Martini, André V. G. Cavalieri +1
Coherent structures are found in many different turbulent flows and are known to drive self-sustaining processes in wall turbulence. Identifying the triadic interactions which gene…
