Phase Transitions in Anisotropic Turbulence
Adrian van Kan
Turbulence is a widely observed state of fluid flows, characterized by complex, nonlinear interactions between motions across a broad spectrum of length and time scales. While turb…

Fluctuation-Induced Transitions in Anisotropic Two-Dimensional Turbulence
Lichuan Xu, Adrian van Kan, Chang Liu +1
Two-dimensional (2D) turbulence features an inverse energy cascade that produces large-scale flow structures such as large-scale vortices (LSVs) and unidirectional jets. We investi…

From a vortex gas to a vortex crystal in instability-driven two-dimensional turbulence
A. van Kan, B. Favier, K. Julien +1
We study structure formation in two-dimensional turbulence driven by an external force, interpolating between linear instability forcing and random stirring, subject to nonlinear d…
