Communities for the Lagrangian Dynamics of the Turbulent Velocity Gradient Tensor: A Network Participation Approach
Christopher J. Keylock, Maurizio Carbone
Complex network analysis methods have been widely applied to nonlinear systems, but applications within fluid mechanics are relatively few. In this paper, we use a network for the…

The Role of Normal and Non-Normal Contributions to Enstrophy Production in the Near-Wall Region of a Turbulent Channel Flow
Christopher J Keylock
The turbulent boundary-layer is a region where both preferential dissipation of energy and the production of significant vorticity arises as a consequence of the strong velocity gr…

Complex network approach to the turbulent velocity gradient dynamics: High- and low-probability Lagrangian paths
Christopher J. Keylock, Maurizio Carbone
Understanding the dynamics of the turbulent velocity gradient tensor (VGT) is essential to gain insights into the Navier-Stokes equations and improve small-scale turbulence modelin…
