The Astrophysical Journal, 2023 Nearly incompressible magnetohydrodynamic (NI MHD) theory for β ∼ 1 (or β ≪ 1) plasma has been developed and applied to the study of solar wind turbulence. The leading-order term in β ∼ 1 or β ≪ 1 plasma describes the majority of 2D turbulence, while the

Spiral Spectrum of a Laguerre-Gaussian Beam Propagating in Anisotropic Turbulent Plasma
IEEE Photonics Journal, 2021 The explicit expression of orbital angular momentum (OAM) spiral spectrum of Laguerre-Gaussian (LG) beam propagating in anisotropic plasma turbulence is derived based on Rytov theory.

Phenomenology of hydromagnetic turbulence in a uniformly expanding medium [PDF]
, 1996 A simple phenomenology is developed for the decay and transport of turbulence in a constant-speed, uniformly expanding medium. The fluctuations are assumed to be locally incompressible, and either of the hydrodynamic or non-Alfvénic magnetohydrodynamic ...

, 1998 The origin of plasma turbulence from currents and spatial gradients in plasmas is described and shown to lead to the dominant transport mechanism in many plasma regimes. A wide variety of turbulent transport mechanism exists in plasmas. In this survey the authors summarize some of the universally observed plasma transport rates.

On Imaging of Plasma Turbulence [PDF]
, 2007 We discuss aspects of imaging of plasma turbulence, taking the standpoint that the imaging is a path for induction of law from complex signals. An example of induction of symbol from signals is illustrated. Then the image of plasma turbulence is extended,

Transport of thermal plasma above the auroral ionosphere in the presence of electrostatic ion-cyclotron turbulence [PDF]
Annales Geophysicae, 1999 The electron component of intensive electric currents flowing along the geomagnetic field lines excites turbulence in the thermal magnetospheric plasma. The protons are then scattered by the excited electromagnetic waves, and as a result the plasma is

Turbulence transport throughout the heliosphere [PDF]
, 2007 We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, the energy per unit mass, the ...

IEEE Journal of Translational Engineering in Health and Medicine, 2021 Objective. Most of the previous studies of drone transport of blood samples examined normal blood samples transported under tranquil air conditions. We studied the effects of 1- and 2-hour drone flights using random vibration and turbulence simulation ...

Kinetic helicity and MHD turbulence [PDF]
, 2000 The issue of dynamical anisotropy in helical three-dimensional magnetohydrodynamic turbulence with a mean magnetic field B₀ is investigated. Using high-resolution direct numerical simulations, we follow the evolution of various isotropic initial states ...

Plasma Turbulence Calculations On Supercomputers [PDF]
The International Journal of Supercomputing Applications, 1990 To predict the size, expense, and performance of mag netic fusion reactors, it is critical to know the scaling of particle transport and losses across the magnetic field with machine and plasma parameters. The mechanism for transport in magnetically confined plasmas is not yet known.
