Turbulence in Fluids, Fourth Revised and Enlarged Edition by Marcel Lesieur. This book is part of the Fluid Mechanics and Its Applications series, edited by R. Moreau. It provides a comprehensive overview of turbulence in fluids, covering both traditional and emerging topics in fluid mechanics. The book is aimed at graduate students and researchers, with a focus on readability and clarity. It includes both monographs and accessible texts, emphasizing the interdisciplinary nature of fluid mechanics. The book is divided into 13 chapters, starting with an introduction to turbulence in fluid mechanics, followed by basic fluid dynamics, transition to turbulence, shear flow turbulence, Fourier analysis of homogeneous turbulence, isotropic turbulence, analytical theories and stochastic models, two-dimensional turbulence, beyond two-dimensional turbulence in geophysical fluid dynamics, statistical thermodynamics of turbulence, statistical predictability theory, large-eddy simulations, and towards real-world turbulence. The book discusses various aspects of turbulence, including statistical approaches, deterministic models, and numerical simulations. It covers topics such as coherent vortices, passive scalar diffusion, and the behavior of turbulence in different environments. The book also addresses the challenges of turbulence modeling, including the need for accurate predictions and the role of numerical simulations in understanding turbulence. The fourth edition incorporates new results from recent research and revisits older topics in the context of these findings. It includes detailed discussions on turbulence in various applications, such as aerodynamics, thermal hydraulics, and environmental engineering. The book also highlights the importance of turbulence in geophysical fluid dynamics, including the study of atmospheric and oceanic flows. The book is supported by numerous illustrations and diagrams, including numerical simulations of turbulent flows, vorticity fields, and passive scalar distributions. It also includes references and an index for further reading. The book is a valuable resource for researchers and students in fluid mechanics, providing a detailed and up-to-date overview of turbulence in fluids.Turbulence in Fluids, Fourth Revised and Enlarged Edition by Marcel Lesieur.
