Resonant quasiparticles in plasma turbulence

Physical Review E, 2003
A general view is proposed on wave propagation in fluids and plasmas where the resonant interaction of monochromatic waves with quasiparticles is considered. A kinetic equation for quasiparticles is used to describe the broadband turbulence interacting with monochromatic waves.

Development of the concepts of plasma turbulence

Uspekhi Fizicheskih Nauk, 1972
The review is devoted to exposition of the physical principles on which the current ideas on plasma turbulence are based. A comparison is made of the results obtained in the theory of plasma turbulence and the turbulence of incompressible liquids. The basic physical differences between hydrodynamic and plasma turbulence are pointed out. It is shown how

Introduction to Turbulence in Magnetised Plasmas

AIP Conference Proceedings, 2005
Turbulence is a complex manifestation of collective plasma behaviour. An introduction to turbulence with particular emphasis on magnetized plasmas is given. This chapter discusses the theoretical background to a leading edge topic in modern plasma physics it is understood to accompany the section on experimental transport studies (Chap. 9 in Part II).

Anomalous resistivity of a turbulent plasma

Plasma Physics, 1971
The conductivity tensor of a turbulent plasma is computed from the coherent response to an external test wave. The enhanced resistivity arises from wave particle interactions and nonlinear coupling between the test wave and the turbulent spectrum. We have included nonexpandable effects due to scattering of particles by the turbulent fluctuations and ...

Plasma Wave Echo in a Weakly Turbulent Plasma

The Physics of Fluids, 1970
The effects of turbulent fluctuations on the plasma wave echo have been investigated for a one-dimensional weakly turbulent electron plasma. It has been found that the interaction between electrons and fluctuations gives rise to (i) damping of the plasma echo, (ii) shift of the maximum position of plasma echo, and (iii) suppression of the peak ...

The anisotropic plasma wave in the plasma turbulence

Contributions to Plasma Physics, 2022
AbstractIn this paper, the influence of plasma turbulence due to the sheared and body stress flow on the dispersion characteristics of the transverse electromagnetic modes in strongly coupled plasma is analysed. Using kinetic theory and solving the scattering relationship for the Vlasov‐Maxwell system, the influence of plasma turbulence on the growth ...

Theory of Strong Turbulence in Plasmas

The Physics of Fluids, 1970
A theory of fluctuations which may be applicable to a plasma in any of the three states, namely, the quiescent, weakly turbulent, and strongly turbulent states, is obtained from an exact solution of the second equation of the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy for the stationary values of the pair correlation function.

Turbulent Particle Transport in Magnetized Plasmas

Physical Review Letters, 2003
Particle transport in magnetized plasmas is investigated with a fluid model of drift wave turbulence. An analytical calculation shows that magnetic field curvature and thermodiffusion drive an anomalous pinch. The curvature driven pinch velocity is consistent with the prediction of turbulence equipartition theory.

Plasma Edge Turbulence

Physical Review Letters, 1983
Model mode-coupling equations for the resistive drift-wave instability are derived and numerically solved to study the properties of turbulence near a plasma edge. The wavenumber spectrum of the turbulence is found to exhibit an inverse cascade to form an isotropic, two-dimensional Kolmogorov spectrum, ${k}^{\ensuremath{-}3}$, in the large-wave-number ...

Electrical Conductivity of a Turbulent Plasma

The Physics of Fluids, 1962
The conductivity of a turbulent plasma parallel to a magnetic field is determined. The plasma is assumed to be homogeneous and the motion of ions is neglected. The ordinary magnetohydrodynamic equations are used. The nonlinear contribution of the product of density and the electric field to the dc conductivity is expressed in terms of the density ...
