Potential applications in tokamak research.3 aThis book reviews and synthesizes recent findings concerning the dynamo effect of beating waves in a turbulent wave field and non-stationary dynamo effect associated with history of evolution of turbulent kinetic and cross helicities. The latter one is based on coexistence of the kinetic and cross helicities in plasma turbulence. Moreover, the physical picture of the non-equilibrium dynamo effect brings in a possible natural interpretation of the phenomenon of magnetic excursions and reversals in natural systems such as the Earth's core, as described in chapter 3. The most important aim of this book is to explain and emphasize the versatile role of non-equilibrium effects in turbulent hydromagnetic dynamos, hitherto typically neglected.  aThe primary market is the community of applied mathematicians, geophysicists and astrophysicists working on dynamo theory and applications to natural systems.  aAlso available in print.  aMode of access: World Wide Web.  aSystem requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.  aKrzysztof Mizerski is an Associate Professor at the Institute of Geophysics of the Polish Academy of Sciences. He has experience in theoretical fluid mechanics in particular the theory of the hydromagnetic dynamo and stratified convection. All of his works have been concerned with analytic approaches to hydrodynamic and magnetohydrodynamic problems supplied by numerical models. These involved investigations of singular structures in boundary layers, linear and nonlinear stability theory and description of fully developed, turbulent stratified convection. One of the main topics of the research conducted by Krzysztof Mizerski is the description of large-scale hydromagnetic dynamos in the fully nonlinear regime, in particular via the renormalization group method. His most recent works were dedicated to creation of a consistent dynamical picture of the hydromagnetic dynamo process induced by nonequilibrium effects in magnetohydrodynamic turbulence. He is an author of a textbook on foundations of convection with density stratification published in 2021 by Springer, Cham.0 aTitle from PDF title page (viewed on January 4, 2024). 0aMagnetohydrodynamics. 0aDynamo theory (Cosmic physics) 0aFluid dynamics. 7aFluid mechanics.2bicssc 7aSCIENCE / Mechanics / Hydrodynamics.2bisacsh2 aInstitute of Physics (Great Britain),epublisher.08iPrint version:z9780750363587z9780750363594 0aIOP (Series).pRelease 23. 0aIOP ebooks.p2023 collection.40uhttps://iopscience.iop.org/book/mono/978-0-7503-6362-4
