The Impact of Turbulence on Physics of the Geomagnetic Tail
Frontiers in Astronomy and Space Sciences, 2021 There is a vast amount of evidence that suggests that the geomagnetic tail is like a turbulent wake behind an obstacle. Large-scale vortices in the wake are able to generate turbulent transport that takes place both along the plasma sheet, in the X and Y

MEMORY EFFECTS IN TURBULENT TRANSPORT [PDF]
The Astrophysical Journal, 2009 In the mean-field theory of magnetic fields, turbulent transport, i.e. the turbulent electromotive force, is described by a combination of the alpha effect and turbulent magnetic diffusion, which are usually assumed to be proportional respectively to the mean field and its spatial derivatives.

Nuclear Fusion, 2023 We assess the turbulent particle transport being responsible for the limitation of the confinement and, thus, the overall performance of the neoclassically optimized stellarator Wendelstein 7-X.

Turbulent Transport in Benard Convection [PDF]
Progress of Theoretical Physics, 2005 Summary: Stochastic evolution equations for turbulent Bénard convection are derived from the Boussinesq equations by transforming the inertial forces into a sum of systematic linear transport terms and random nonlinear fluctuating forces by means of the projection operator method.

Direct Numerical Simulation of Supersonic Turbulent Boundary Layer with Spanwise Wall Oscillation
Energies, 2016 Direct numerical simulations (DNS) of Mach = 2.9 supersonic turbulent boundary layers with spanwise wall oscillation (SWO) are conducted to investigate the turbulent heat transport mechanism and its relation with the turbulent momentum transport.

Optimizing Stellarators for Turbulent Transport [PDF]
Physical Review Letters, 2010 Up to now, the term "transport-optimized" stellarators has meant optimized to minimize neoclassical transport, while the task of also mitigating turbulent transport, usually the dominant transport channel in such designs, has not been addressed, due to the complexity of plasma turbulence in stellarators.

Cosmic-ray Transport in Magnetohydrodynamic Turbulence
The Astrophysical Journal, 2022 Abstract This paper studies cosmic-ray (CR) transport in magnetohydrodynamic (MHD) turbulence. CR transport is strongly dependent on the properties of the magnetic turbulence. We perform test particle simulations to study the interactions of CR with both total MHD turbulence and decomposed MHD modes.

Statistical Conservation Laws in Turbulent Transport [PDF]
Physical Review Letters, 2001 We address the statistical theory of fields that are transported by a turbulent velocity field, both in forced and in unforced (decaying) experiments. We propose that with very few provisos on the transporting velocity field, correlation functions of the transported field in the forced case are dominated by statistically preserved structures.

A Quantitative Scaling Theory for Meridional Heat Transport in Planetary Atmospheres and Oceans
AGU Advances, 2021 The meridional temperature profile of the upper layers of planetary atmospheres is set through a balance between differential radiative heating by a nearby star, or by intrinsic heat fluxes emanating from the deep interior, and the redistribution of that
