Coherent-structure dynamics in wall turbulence from state-space trajectories
Emma Lenz, Ahmed Elnahhas, H. Jane Bae
We identify dynamical processes in the near-wall region of turbulent wall-bounded flow by representing coherent-structure energy as trajectories in a low-dimensional state space an…

Are the dynamics of wall turbulence in minimal channels and larger domain channels equivalent? A graph-theoretic approach
Ahmed Elnahhas, Emma Lenz, Parviz Moin +2
This work proposes two algorithmic approaches to extract critical dynamical mechanisms in wall-bounded turbulence with minimum human bias. In both approaches, multiple types of coh…
