The edge as a Lagrangian Coherent Structure in a high-dimensional state space
TL;DR: In this paper, Lagrangian data analysis is applied to investigate the edge manifold of dissipative dynamical systems, which separates trajectories attracted by the laminar state from those reaching the turbulent state.

TL;DR: In this paper, the stability of generic boundary layer flows is studied from a global viewpoint using optimization methods using global eigenmodes of the incompressible linearized Navier-Stokes equations are computed using the Krylov subspace Arnoldi method.

The use of global modes to understand transition and perform flow control
TL;DR: In this article, the stability of non-parallel flows is considered using superposition of global modes, and the optimal perturbation analysis shows that the worst case initial condition is a localized disturbance that creates a propagating wave packet that hits the downstream end, regenerating a wave packet upstream through a global pressure pulse.

Unsteady Response of Natural Laminar Flow Airfoil Undergoing Small-Amplitude Pitch Oscillations
TL;DR: In this paper, largeeddy simulations are performed to investigate the dynamic response of a natural laminar flow airfoil undergoing harmonic small-amplitude pitch oscillations at a chord-based Reynolds number of oscillations.

Forcing statistics in resolvent analysis: application in minimal turbulent Couette flow
Petrônio A. S. Nogueira,Pierluigi Morra,Eduardo Martini,André V. G. Cavalieri,Dan S. Henningson +4 more
TL;DR: In this paper, an analysis of the statistics of the non-linear terms in resolvent analysis is performed for turbulent Couette flow at low Reynolds number, where the covariance matrix of the forcing is derived from a direct numerical simulation of a minimal flow unit.
