This book was released on 2010 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: We first present the mathematical formulation of the solution of this equation. Then, we focus on the numerical tools to simulate plasma turbulence. A finite difference scheme is properly derived so that the interaction between grid points conserves quadratic quantities of physical importance such as mean kinetic energy and mean square vorticity, thus preventing nonlinear computational instabilities and thereby permitting long-term numerical integrations. The discretization of the nonlinear term used was developed by A. Arakawa [6] who showed how the integral constraints on the Jacobian can be maintained using a combination of finite difference schemes. In order to validate our code, we conduct several numerical tests based on turbulence theory. Namely, we show that a modon is stationary in our simulation and that the periodic boundary conditions do not lead to additional deformation or dissipation of the solution.

Modern concepts, tools and approaches to studying turbulence and coherent structures are introduced by world-class experts in several fields. The book covers theoretical approaches, numerical modeling and experimental methods in quasi-two-dimensional geophysical flows (such as oceans and atmospheres), turbulence and structures in ionized gases (such as magnetized plasma), three-dimensional flows (such as turbulent boundary layers), and also vortices and solutions in nonlinear optical medium. Many of the methodologies presented may also be applicable to other complex systems. One of the main objectives of this book is to introduce modern studies of turbulence as a cross-disciplinary domain and to give the reader exposure to some of the most vital theoretical and experimental areas of turbulence research.
Book Synopsis On the Edge of Magnetic Fusion Devices by : Sergei Krasheninnikov
Download or read book On the Edge of Magnetic Fusion Devices written by Sergei Krasheninnikov and published by Springer Nature. This book was released on 2020-09-07 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the current state of understanding concerning edge plasma, which bridges hot fusion plasma, with a temperature of roughly one million degrees Kelvin with plasma-facing materials, which have melting points of only a few thousand degrees Kelvin. In a fact, edge plasma is one of the keys to solution for harnessing fusion energy in magnetic fusion devices. The physics governing the processes at work in the edge plasma involves classical and anomalous transport of multispecies plasma, neutral gas dynamics, atomic physics effects, radiation transport, plasma-material interactions, and even the transport of plasma species within the plasma-facing materials. The book starts with simple physical models, then moves on to rigorous theoretical considerations and state-of-the-art simulation tools that are capable of capturing the most important features of the edge plasma phenomena. The authors compare the conclusions arising from the theoretical and computational analysis with the available experimental data. They also discuss the remaining gaps in their models and make projections for phenomena related to edge plasma in magnetic fusion reactors.

Book Synopsis Coherent Vortex Structures in Fluids and Plasmas by : Anatoli Tur
Download or read book Coherent Vortex Structures in Fluids and Plasmas written by Anatoli Tur and published by Springer. This book was released on 2017-04-09 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph introduces readers to the hydrodynamics of vortex formation, and reviews the last decade of active research in the field, offering a unique focus on research topics at the crossroads of traditional fluids and plasmas. Vortices are responsible for the process of macroscopic transport of momentum, energy and mass, and are formed as the result of spontaneous self-organization. Playing an important role in nature and technology, localized, coherent vortices are regularly observed in shear flows, submerged jets, afterbody flows and in atmospheric boundary layers, sometimes taking on the form of vortex streets. In addition, the book addresses a number of open issues, including but not limited to: which singularities are permitted in a 2D Euler equation besides point vortices? Which other, even more complex, localized vortices could be contained in the Euler equation? How do point vortices interact with potential waves?

Book Synopsis Energy Transfer and Dissipation in Plasma Turbulence by : Yan Yang
Download or read book Energy Transfer and Dissipation in Plasma Turbulence written by Yan Yang and published by Springer. This book was released on 2019-05-02 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2006 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the lectures delivered at the 19th Canberra International Physics Summer School held at the Australian National University in Canberra (Australia) in January 2006.The problem of turbulence and coherent structures is of key importance in many fields of science and engineering. It is an area which is vigorously researched across a diverse range of disciplines such as theoretical physics, oceanography, atmospheric science, magnetically confined plasma, nonlinear optics, etc. Modern studies in turbulence and coherent structures are based on a variety of theoretical concepts, numerical simulation techniques and experimental methods, which cannot be reviewed effectively by a single expert.The main goal of these lecture notes is to introduce state-of-the-art turbulence research in a variety of approaches (theoretical, numerical simulations and experiments) and applications (fluids, plasmas, geophysics, nonlinear optical media) by several experts. A smooth introduction is presented to readers who are not familiar with the field, while reviewing the most recent advances in the area. This collection of lectures will provide a useful review for both postgraduate students and researchers new to the advancements in this field, as well as specialists seeking to expand their knowledge across different areas of turbulence research.

Available in PDF, EPUB and Kindle. Book excerpt: For a few seconds with large machines, scientists and engineers have now created the fusion power of the stars in the laboratory and at the same time find the rich range of complex turbulent electromagnetic waves that transport the plasma confinement systems. The turbulent transport mechanisms created in the laboratory are explained in detail in the second edition of 'Turbulent Transport in Magnetized Plasmas' by Professor Horton.The principles and properties of the major plasma confinement machines are explored with basic physics to the extent currently understood. For the observational laws that are not understood — the empirical confinement laws — offering challenges to the next generation of plasma students and researchers — are explained in detail. An example, is the confinement regime — called the 'I-mode' — currently a hot topic — is explored.Numerous important problems and puzzles for the next generation of plasma scientists are explained. There is growing demand for new simulation codes utilizing the massively parallel computers with MPI and GPU methods. When the 20 billion dollar ITER machine is tested in the 2020ies, new theories and faster/smarter computer simulations running in near real-time control systems will be used to control the burning hydrogen plasmas.
Book Synopsis Simulating Space Plasmas in the Lab by : Marlon
Download or read book Simulating Space Plasmas in the Lab written by Marlon and published by Tredition Gmbh. This book was released on 2024-07-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intermittency is a defining characteristic of turbulence, and can be described as "the nonuni-form distriubtion of eddy formations in a stream" [55]. Spatial intermittency occurs when turbulent eddies are generated over a wide range of scales but do not fill the fluid volume, only irregu-lar sub-volumes [56]; this is associated with sharp gradients and coherent structures. Temporal intermittency occurs when fluctuations appear as "bursts" in time with varying durations and is characteristic of the turbulent cascade. Matthaeus and co-authors review the properties of spatial and temporal intermittency in both fluids and plasmas [57]. Intermittency is related to nonlinear phase-space structures called "holes" and "clumps" which were originally found in electrostatic turbulence simulations [58, 59]. Temporal intermittency has been associated with the inverse cas-cade of two-dimensional turbulence, as described in Section 1.3.
