The instability of fluid flows is a key topic in classical fluid mechanics because it has huge repercussions for applied disciplines such as chemical engineering, hydraulics, aeronautics, and geophysics. This modern introduction is written for any student, researcher, or practitioner working in the area, for whom an understanding of hydrodynamic instabilities is essential. Based on a decade's experience of teaching postgraduate students in fluid dynamics, this book brings the subject to life by emphasizing the physical mechanisms involved. The theory of dynamical systems provides the basic structure of the exposition, together with asymptotic methods. Wherever possible, Charru discusses the phenomena in terms of characteristic scales and dimensional analysis. The book includes numerous experimental studies, with references to videos and multimedia material, as well as over 150 exercises which introduce the reader to new problems.

This book demonstrates the capabilities of passive microwave technique for enhanced observations of ocean features, including the detection of (sub)surface events and/or disturbances while laying out the benefits and boundaries of these methods. It represents not only an introduction and complete description of the main principles of ocean microwave radiometry and imagery, but also provides guidance for further experimental studies. Furthermore, it expands the analysis of remote sensing methods, models, and techniques and focuses on a high-resolution multiband imaging observation concept. Such an advanced approach provides readers with a new level of geophysical information and data acquisition granting the opportunity to improve their expertise on advanced microwave technology, becoming now an indispensable tool for diagnostics of ocean phenomena and disturbances.

This book describes in detail the scientific philosophy of the formation and stabilization-destabilization of foams. It presents all hierarchical steps of a foam, starting from the properties of adsorption layers formed by foaming agents, discussing the properties of foam films as the building blocks of a foam, and then describing details of real foams, including many fields of application. The information presented in the book is useful to people working on the formulation of foams or attempting to avoid or destruct foams in unwanted situations.

Falling Liquid Films gives a detailed review of state-of-the-art theoretical, analytical and numerical methodologies, for the analysis of dissipative wave dynamics and pattern formation on the surface of a film falling down a planar inclined substrate. This prototype is an open-flow hydrodynamic instability, that represents an excellent paradigm for the study of complexity in active nonlinear media with energy supply, dissipation and dispersion. It will also be of use for a more general understanding of specific events characterizing the transition to spatio-temporal chaos and weak/dissipative turbulence. Particular emphasis is given to low-dimensional approximations for such flows through a hierarchy of modeling approaches, including equations of the boundary-layer type, averaged formulations based on weighted residuals approaches and long-wave expansions. Whenever possible the link between theory and experiment is illustrated, and, as a further bridge between the two, the development of order-of-magnitude estimates and scaling arguments is used to facilitate the understanding of basic, underlying physics. This monograph will appeal to advanced graduate students in applied mathematics, science or engineering undertaking research on interfacial fluid mechanics or studying fluid mechanics as part of their program. It will also be of use to researchers working on both applied, fundamental theoretical and experimental aspects of thin film flows, as well as engineers and technologists dealing with processes involving isothermal or heated films. This monograph is largely self-contained and no background on interfacial fluid mechanics is assumed.

A Physical Introduction to Suspension Dynamics

Understanding the behaviour of particles suspended in a fluid has many important applications across a range of fields, including engineering and geophysics. Comprising two main parts, this book begins with the well-developed theory of particles in viscous fluids, i.e. microhydrodynamics, particularly for single- and pair-body dynamics. Part II considers many-body dynamics, covering shear flows and sedimentation, bulk flow properties and collective phenomena. An interlude between the two parts provides the basic statistical techniques needed to employ the results of the first (microscopic) in the second (macroscopic). The authors introduce theoretical, mathematical concepts through concrete examples, making the material accessible to non-mathematicians. They also include some of the many open questions in the field to encourage further study. Consequently, this is an ideal introduction for students and researchers from other disciplines who are approaching suspension dynamics for the first time.

Fluid mechanics is a branch of classical physics that has a rich tradition in applied mathematics and numerical methods. It is at work virtually everywhere, from nature to technology. This broad and fundamental coverage of computational fluid dynamics (CFD) begins with a presentation of basic numerical methods and flows into a rigorous introduction to the subject. A heavy emphasis is placed on the exploration of fluid mechanical physics through CFD, making this book an ideal text for any new course that simultaneously covers intermediate fluid mechanics and computation. Ample examples, problems and computer exercises are provided to allow students to test their understanding of a variety of numerical methods for solving flow physics problems, including the point-vortex method, numerical methods for hydrodynamic stability analysis, spectral methods and traditional CFD topics.

Was ist Fluid-Turbulenz?

Es wird eine innovative Wellenstrukturtheorie der Turbulenz vorgestellt. Der wichtigste Fortschritt ist die Bereitstellung von Turbulenzparametern aus theoretischen Untersuchungen der optimalen Selbstorganisation der Turbulenz durch Bewertungen mit Hilfe der Informationsentropie. Die neuen theoretischen Ergebnisse stimmen mit den experimentell gesicherten Resultaten turbulenter Konvektionsgeschwindigkeitsfelder bei freier und erzwungener Turbulenz sehr gut überein. Im Zusammenhang mit dem logarithmischen Wandgesetz wird gezeigt, dass es keine viscose Unterschicht gibt. Die Formulierung des Oszillationsproblems der Turbulenz und die Lösung der Randwertaufgaben mit an die konkrete Aufgabenstellung angepassten Koordinatensystemen erfolgt für viele technisch bedeutsame turbulente Strömungen, u.a. glatte und raue Rohrströmung, Konfusor- und Diffusorströmung, Drallströmung, Rührerströmung, Einlaufströmung, Intermittenz, Nachlaufströmung und Freistrahlen. Eine erkenntnistheoretische Komponente der Innovation ist die Darstellung der Turbulenz durch kontravariante Vektorfelder, die sich durch die Beständigkeit der Turbulenzstrukturen bei Veränderung der Strukturdichte auszeichnen. Die Turbulenzstrukturen wirken als aktive Impulssender gebrochener Monopole, Dipole, Tripole und Quadrupole im Strömungsfeld. Der Dissipationsmechanismus wird qualitativ und quantitativ erstmalig hinsichtlich der Prozesse in den Turbulenzstrukturen beschrieben. Den Übergang vom kontravarianten Turbulenzgeschwindigkeitsfeld zum kovarianten Konvektionsgeschwindigkeitsfeld ermöglichen die Brechung und Verschränkung. Es wirken die Prinzipien der Turbulenz als Fraktalprinzip, Spiegelungsprinzip, Verschränkungsprinzip, Brechungsprinzip und Faltungsprinzip Die Wellenstrukturtheorie der Turbulenz bietet ein ordnendes Instrument weiterer Untersuchungen zu zahlreichen offenen Problemen.
