MHD turbulence [PDF]

open access: yesLiving Reviews in Solar Physics, 2019
AbstractWe review the current status of research in MHD turbulence theory and numerical experiments and their applications to astrophysics and solar science. We introduce general tools for studying turbulence, basic turbulence models, MHD equations and their wave modes. Subsequently, we cover the theories and numerics of Alfvénic turbulence, imbalanced

Is 2D turbulence a conformal turbulence? [PDF]

open access: yesPhysical Review Letters, 1993
A critical analysis of the conformal approach to the theory of 2d turbulence is delivered. It is shown, in particular, that conformal minimal models cannot give a general turbulent solution, which should provide for constant fluxes of all vorticity integrals of motion.

Turbulent Firms, Turbulent Wages? [PDF]

open access: yesSSRN Electronic Journal, 2006
Has greater turbulence among firms fueled rising wage instability in the United States? Earlier research by Gottschalk and Moffitt shows that rising earnings instability was responsible for one-third to one-half of the rise in wage inequality during the 1980s. These growing transitory fluctuations remain largely unexplained. To help fill this gap, this

Holographic Turbulence [PDF]

open access: yesPhysical Review Letters, 2014
We construct turbulent black holes in asymptotically AdS_4 spacetime by numerically solving Einstein equations. Both the dual holographic fluid and bulk geometry display signatures of an inverse cascade with the bulk geometry being well approximated by the fluid/gravity gradient expansion.

Stirring turbulence with turbulence [PDF]

open access: yesPhysics of Fluids, 2015
We stir wind-tunnel turbulence with an active grid that consists of rods with attached vanes. The time-varying angle of these rods is controlled by random numbers. We study the response of turbulence on the statistical properties of these random numbers.

Fibonacci Turbulence [PDF]

open access: yesPhysical Review X, 2021
Never is the difference between thermal equilibrium and turbulence so dramatic, as when a quadratic invariant makes the equilibrium statistics exactly Gaussian with independently fluctuating modes. That happens in two very different yet deeply connected classes of systems: incompressible hydrodynamics and resonantly interacting waves.

Transitional–turbulent spots and turbulent–turbulent spots in boundary layers [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
SignificanceUncovering the constitutive coherent structure in the inner layer of the canonical turbulent boundary layer has remained a central fluid mechanics theme, because it tests our intellectual ability to understand even the simplest external flow.

Turbulence dynamics near a turbulent/non-turbulent interface [PDF]

open access: yesJournal of Fluid Mechanics, 2012
AbstractThe characteristics of the boundary layer separating a turbulence region from an irrotational (or non-turbulent) flow region are investigated using rapid distortion theory (RDT). The turbulence region is approximated as homogeneous and isotropic far away from the bounding turbulent/non-turbulent (T/NT) interface, which is assumed to remain ...
