Critical balance in magnetohydrodynamic, rotating and stratified turbulence : towards a universal scaling conjecture [PDF]
, 2009 It is proposed that critical balance - a scale-by-scale balance between the linear propagation and nonlinear interaction time scales - can be used as a universal scaling conjecture for determining the spectra of strong turbulence in anisotropic wave ...

Transport barrier onset and edge turbulence shortfall in fusion plasmas
Communications Physics, 2022 A central problem in magnetized fusion plasmas is to understand whether the plasma edge sustains a turbulent state and transitions to improved confinement.

α Effect and Magnetic Diffusivity β in Helical Plasma Under Turbulence Growth
UniverseWe investigate the transport coefficients α and β in plasma systems with varying Reynolds numbers while maintaining a unit magnetic Prandtl number (PrM). The α and β tensors parameterize the turbulent electromotive force (EMF) in terms of the large-scale

Dynamical age of solar wind turbulence in the outer heliosphere [PDF]
, 1998 In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity.

Statistical Theory of Plasmas Turbulence [PDF]
Plasma and Fusion Research, 2009 We present a statistical theory of intermittency in plasma turbulence based on short-lived coherent structures (instantons). In general, the probability density functions (PDFs) of the flux R are shown to have an exponential scaling P(R) ∝ exp (-cRs ) in the tails.

Three-dimensional spatial structures of solar wind turbulence from 10 000-km to 100-km scales [PDF]
, 2011 Using the four Cluster spacecraft, we have determined the three-dimensional wave-vector spectra of fluctuating magnetic fields in the solar wind. Three different solar wind intervals of Cluster data are investigated for this purpose, representing ...

Anisotropic three-dimensional MHD turbulence [PDF]
, 1996 Direct spectral method simulation of the three-dimensional magnetohydrodynamics (MHD) equations is used to explore anisotropy that develops from initially isotropic fluctuations as a consequence of a uniform applied magnetic field.

Shadowing effects in simulated Alcator C-Mod gas puff imaging data
Nuclear Materials and Energy, 2019 A synthetic gas puff imaging (GPI) diagnostic is applied to a gyrokinetic turbulence simulation of Alcator C-Mod with the objective of assessing the impact of turbulent plasma fluctuations on the GPI neutral density field.
