Random and quasi-coherent aspects in particle motion and their effects on transport and turbulence evolution
M Vlad, F Spineanu - New Journal of Physics, 2017 - iopscience.iop.org
The quasi-coherent effects in two-dimensional incompressible turbulence are analyzed
starting from the test particle trajectories. They can acquire coherent aspects when the …

Nonlinear saturation and oscillations of collisionless zonal flows
In homogeneous drift-wave turbulence, zonal flows (ZFs) can be generated via a
modulational instability (MI) that either saturates monotonically or leads to oscillations of the …

Phase-Space Theory of Drift Wave-Zonal Flow Interactions and the Dimits Shift
H Zhu - 2020 - search.proquest.com
Zonal flows (ZFs) play a crucial role in regulating drift-wave (DW) turbulence. ZFs can even
completely suppress DWs near the linear-instability threshold, which is known as the Dimits …
