Book Description
This book revisits the long-standing puzzle of cross-scale energy transfer and dissipation in plasma turbulence and introduces new perspectives based on both magnetohydrodynamic (MHD) and Vlasov models. The classical energy cascade scenario is key in explaining the heating of corona and solar wind. By employing a high-resolution hybrid (compact finite difference & WENO) scheme, the book studies the features of compressible MHD cascade in detail, for example, in order to approximate a real plasma cascade as “Kolmogorov-like” and to understand features that go beyond the usual simplified theories based on incompressible models. When approaching kinetic scales where plasma effects must be considered, it uses an elementary analysis of the Vlasov–Maxwell equations to help identify the channels through which energy transfer must be dissipated. In addition, it shows that the pressure–strain interaction is of great significance in producing internal energy. This analysis, in contrast to many other recent studies, does not make assumptions about wave-modes, instability or other specific mechanisms responsible for the dynamics – the results are direct consequences of the Vlasov–Maxwell system of equations. This is an important step toward understanding dissipation in turbulent collisionless plasma in space and astrophysics.

Magnetohydrodynamics of Plasma Relaxation
Author: S. Ortolani
Publisher: World Scientific
ISBN: 9789810208608
Category : Science
Languages : en
Pages : 208
Book Description
This book gives a concise description of the phenomenon of plasma relaxation from the point of view of resistive magnetohydrodynamic (MHD) theory. Magnetized plasmas relax when they seek their natural state of lowest energy subject to certain topological constraints imposed by the magnetic field. Relaxation may be fast and dynamic or slow and gradual depending on the external environment in which the magnetoplasma system evolves. Relaxation occurs throughout the universe and may describe such diverse phenomena as dynamos, solar flares, and the operation of magnetic fusion energy experiments. This book concentrates on the dynamic, rather than variational aspects of relaxation. While the processes described are general, the book focuses on the reversed-field pinch experiment as a paradigm for plasma relaxation and dynamo action. Examples from other branches of plasma physics are also discussed. The authors draw upon their extensive experience in numerical and experimental studies of relaxation.

Plasma Physics and Problems of Magnetohydrodynamics in the Transformation of Energy

Languages : en
Pages : 27
Book Description
Progress being made in creating magnetohydrodynamic generators in the Soviet Union is described. The article opens with a general discussion of the problems encountered in transforming the energy contained in chemical fuels into electrical energy. Efforts to overcome these problems have led to magnetohydromagnetic generators in which current is caused to flow in liquid, gas (plasma), or gas-liquid conductors moving through a magnetic field. Implementation of this principle has become possible in recent years due to development of good liquid and gas conductors, new heat-resistant materials, high temperature technology, the technology of superstrong magnetic fields, and large superconducting magnetic systems.
