  Description. Mean-Field Magnetohydrodynamics and Dynamo Theory provides a systematic introduction to mean-field magnetohydrodynamics and the dynamo theory, along with the results achieved. Topics covered include turbulence and large-scale structures; general properties of the turbulent electromotive force; homogeneity, isotropy, and mirror symmetry of turbulent fields; and turbulent electromotive force in the case of non-vanishing mean Edition: 1. Mean-field magnetohydrodynamics and dynamo theory - NASA/ADS. The book discussed is intended to give a systematic introduction to mean-field magnetohydrodynamics and the dynamo theory which is based on it, and to provide a survey of the results achieved. Basic ideas of mean-field electrodynamics are considered along with the elementary treatment of a simple example, general Cited by: adshelp[at] The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86ACited by: SAO/NASA Astrophysics Data System (ADS) Title: Book-Review - Mean-Field Magnetohydrodynamics and Dynamo Theory Authors: Krause, T., Radler, K.

About this book Magnetohydrodynamics (MHD) studies the interaction between the flow of an electrically conducting fluid and magnetic fields. It involves such diverse topics as the evolution and dynamics of astrophysical objects, thermonuclear fusion, metallurgy . This state-of-the-art book aims at revising the evolution of ideas in various branches of magnetohydrodynamics (astrophysics, earth and solar dynamos, plasmas, MHD turbulence and liquid metals) and reviews current trends and challenges. Exploring the origins and evolution of magnetic fields in planets, stars and galaxies, this book gives a basic introduction to magnetohydrodynamics and surveys the observational data, with particular focus on geomagnetism and solar magnetism. Pioneering laboratory experiments that seek to replicate particular aspects of fluid dynamo action are also described. The magnetic eld B = (Bp;Bt) has two parts: the poloidal component Bp = r A, and the toroidal component Bt, where A is the vector potential of the magnetic eld. The principal point of the mean- eld dynamo theory is the separation of the physical elds onto the large- and small-scale counterparts.

Part of the Fluid Mechanics And Its Applications book series (FMIA, volume 80) Mean-field dynamo theory has proved to be a useful tool for understanding the generation of magnetic fields in the Earth and the Sun, in stellar bodies, and even in galaxies. It provides a basis for the elaboration of detailed dynamo models of these objects. Abstract Mean-field theory describes magnetohydrodynamic processes leading to large-scale magnetic fields in various cosmic objects. In this study magnetoconvection and dynamo processes in a rotating spherical shell are considered. Mean fields are defined by azimuthal averaging. Mean-field magnetohydrodynamics and dynamo theory. Oxford ; New York: Pergamon Press, © (OCoLC) Document Type: Book: All Authors / Contributors: F Krause; K H Rädler. Book Description Although the origin of Earth's and other celestial bodies' magnetic fields remains unknown, we do know that the motion of electrically conducting fluids generates and maintains these fields, forming the basis of magnetohydrodynamics (MHD) and, to a larger extent, dynamo theory.
