Theory and modelling with direct numerical simulation and experimental observations are indispensable in the understanding of the evolution of nature, in this case the theory and modelling of plasma and fluid turbulence. Plasma and Fluid Turbulence: Theory and Modelling explains modelling methodologies in depth with regard to turbulence phenomena and turbulent transport both in fluids and plasmas. Special attention is paid to structural formation and transitions.In this detailed book, the authors examine the underlying ideas describing turbulence, turbulent transport, and structural transitions in plasmas and fluids. By comparing and contrasting turbulence in fluids and plasmas, they demonstrate the basic physical principles common to fluids and plasmas while also highlighting particular differences. The book also discusses the application of these ideas to neutral fluids.Part I presents a general introduction to turbulence and structural formation in fluids and plasmas, and Part II explains methodologies for fluid turbulence. In Part III, the authors describe the subjects in magnetohydrodynamics, in particular, dynamo problems. The final section, Part IV, considers plasma turbulence and transport.

Giving a comprehensive overview of turbulence modelling, this text looks at both the conventional and statistical-theoretical viewpoints. The mathematical structures of primary turbulence models such as algebraic (turbulent-viscosity-type), second-order, and subgrid-scales ones are elucidated, and the relationship between them is shown systematically. This approach is extended to turbulent or mean-field dynamo that plays an important role in the study of the generation and sustainment mechanisms of magnetic fields in astro-geophysical and fusion phenomena. Finally, turbulence modelling is shown to be a concept possessing a wide range of applicability in both the practical and academic senses. Readers are expected to have a basic knowledge of fluid mechanics at a graduate level and beyond. The important properties of turbulence necessary for turbulence modelling, however, are explained in a self-consistent manner. This text is therefore suited for both graduate students and researchers who are interested in turbulence modelling and turbulent dynamo.
