POD-based study of turbulent plane Poiseuille flow: comparing structure and dynamics between quasi-linear simulations and DNS
Marios-Andreas Nikolaidis, Petros J. Ioannou, Brian F. Farrell +1
Turbulence in the restricted nonlinear (RNL) dynamics is analyzed and compared with DNS of Poiseuille turbulence at . The structures are obtained by POD analysis of the two…

Synchronization of Low Reynolds Number Plane Couette Turbulence
Marios-Andreas Nikolaidis, Petros J. Ioannou
We demonstrate that a separation of the velocity field in large and small scales according to a streamwise Fourier decomposition identifies subspaces with stable Lyapunov exponents…
