Review of plasma turbulence experiments. [PDF]

Proc Jpn Acad Ser B Phys Biol Sci, 2021
Understandings of turbulent plasma have been developed along with nuclear fusion research for more than a half century. Long international research has produced discoveries concerning turbulent plasma that allow us to notice the hidden nature and physics questions that could contribute to other scientific fields and the development of technologies ...

Fluidization of collisionless plasma turbulence. [PDF]

Proc Natl Acad Sci U S A, 2019
Significance Two textbook physical processes compete to thermalize turbulent fluctuations in collisionless plasmas: Kolmogorov’s “cascade” to small spatial scales, where dissipation occurs, and Landau’s damping, which transfers energy to small scales in velocity space via “phase mixing,” also leading to dissipation. We show that, in a

Supersonic plasma turbulence in the laboratory. [PDF]

Nat Commun, 2019
AbstractThe properties of supersonic, compressible plasma turbulence determine the behavior of many terrestrial and astrophysical systems. In the interstellar medium and molecular clouds, compressible turbulence plays a vital role in star formation and the evolution of our galaxy.

Fluid Turbulence in Quantum Plasmas [PDF]

Physical Review Letters, 2007
Nonlinear fluid simulations are developed by us to investigate the properties of fully developed two-dimensional (2D) electron fluid turbulence in a very dense Fermi (quantum) plasma. We find that a 2D quantum electron plasma exhibits dual cascades, in which the electron number density cascades towards smaller turbulent scales, while the electrostatic ...

Turbulent dynamo in a collisionless plasma [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Although magnetic field amplification by a dynamo effect converting kinetic flow energy into magnetic energy has long been shown in conventional magnetohydrodynamic fluids, whether a similar effect is possible in more dynamically complex weakly collisional plasmas, such as those encountered in astrophysical objects on ...

ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

Hepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

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.

Plasma turbulence [PDF]

, 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.

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.

α Effect and Magnetic Diffusivity β in Helical Plasma Under Turbulence Growth

Universe
We 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
