The spectral dynamics and spatial structures of the conditional Lyapunov vector in slave Kolmogorov flow
Jian Li, Wenwen Si, Yi Li
We conduct direct numerical simulations to investigate the synchronization of Kolmogorov flows in a periodic box, with a focus on the mechanisms underlying the asymptotic evolution…

Intrinsic relationship between synchronisation thresholds and Lyapunov vectors: evidence from large eddy simulations and shell models
Jian Li, Wenwen Si, Yi Li +1
An important parameter characterising the synchronisation of turbulent flows is the threshold coupling wavenumber. This study investigates the relationship between the threshold co…
