Turbulence in Rotating, Stratified and Electrically Conducting Fluids

by P. A. Davidson

There are two recurring themes in astrophysical and geophysical fluid mechanics: waves and turbulence. This book investigates how turbulence responds to rotation, stratification or magnetic fields, identifying common themes, where they exist, as well as the essential differences which inevitably arise between different classes of flow. The discussion is developed from first principles, making the book suitable for graduate students as well as professional researchers. The author focuses first on the fundamentals and then progresses to such topics as the atmospheric boundary layer, turbulence in the upper atmosphere, turbulence in the core of the earth, zonal winds in the giant planets, turbulence within the interior of the sun, the solar wind, and turbulent flows in accretion discs. The book will appeal to engineers, geophysicists, astrophysicists and applied mathematicians who are interested in naturally occurring turbulent flows.

Turbulence in the Solar Wind

by Roberto Bruno Vincenzo Carbone

This book provides an overview of solar wind turbulence from both the theoretical and observational perspective. It argues that the interplanetary medium offers the best opportunity to directly study turbulent fluctuations in collisionless plasmas. In fact, during expansion, the solar wind evolves towards a state characterized by large-amplitude fluctuations in all observed parameters, which resembles, at least at large scales, the well-known hydrodynamic turbulence. This text starts with historical references to past observations and experiments on turbulent flows. It then introduces the Navier-Stokes equations for a magnetized plasma whose low-frequency turbulence evolution is described within the framework of the MHD approximation. It also considers the scaling of plasma and magnetic field fluctuations and the study of nonlinear energy cascades within the same framework. It reports observations of turbulence in the ecliptic and at high latitude, treating Alfv#65533;nic and compressive fluctuations separately in order to explain the transport of mass, momentum and energy during the expansion. Further, existing models are compared with direct observations in the heliosphere. The problem of self-similar and anomalous fluctuations in the solar wind is then addressed using tools provided by dynamical system theory and discussed on the basis of available models and observations. The book highlights observations of Yaglom's law in solar wind turbulence, which is one of the most important findings in fully developed turbulence and directly related to the long-lasting and still unsolved problem of solar wind plasma heating. Lastly, it includes a short chapter dedicated to the kinetic range of fluctuations, which has recently been receiving more attention from the space plasma community, since this is inherently related to turbulent energy dissipation and consequent plasma heating. It particularly focuses on the nature and role of the fluctuations populating this frequency range, and discusses several model predictions and recent observational findings in this context.

The Turbulence Problem: A Persistent Riddle in Historical Perspective (SpringerBriefs in History of Science and Technology)

by Michael Eckert

On the road toward a history of turbulence, this book focuses on what the actors in this research field have identified as the “turbulence problem”. Turbulent flow rose to prominence as one of the most persistent challenges in science. At different times and in different social and disciplinary settings, the nature of this problem has changed in response to changing research agendas. This book does not seek to provide a comprehensive account, but instead an exemplary exposition on the environments in which problems become the subjects of research agendas, with particular emphasis on the first half of the 20th century.

Turbulence—an Odyssey: Origins and Evolution of a Research Field at the Interface of Science and Engineering (History of Physics)

by Michael Eckert

Turbulence is a research field where high expectations have met with recurrent frustration. It is a common perception among physicists, mathematicians and engineers that there is a "big mystery" behind the phenomenon of turbulence. Its history has also remained anything but well researched. Unlike topics such as quantum theory, which began to attract physics historians as long as fifty years ago, turbulence has - until now - received only little professional historical investigation. In this book, which complements his earlier SpringerBrief "The Turbulence Problem", the author sketches the history of turbulence from the vantage point of its roots (Part I), the basic concepts (Part II) and the formation of a scientific community that regarded turbulence as a research field in its own right (Part III). From this perspective turbulence research appears to undertake an odyssey through uncharted territories. The book follows this development up until a conference in Marseille in the year 1961, which marked the inauguration of turbulence in the words of its organizer as “a new science”. The epilogue contains some observations about turbulence research since 1961. This book provides a rich source of information for all those interested in the history of this major field of basic and applied science.

Turbulent Cascades II: Proceedings of the Euromech-ERCOFTAC Colloquium 589 (ERCOFTAC Series #26)

by Mikhael Gorokhovski Fabien S. Godeferd

Gathering contributions by the most prominent researchers in a highly specialised field, this proceedings volume clarifies selected aspects of the physics of turbulent cascades and their statistical universalities under complex stationary and non-homogeneous conditions. Here, these conditions are induced by the presence of a gas/liquid interface, inertial particles, strong shear, rotation, MHD and stratification. By proposing different ways to model turbulence effects under these complex conditions, the book will be of considerable interest not only to academic researchers, but also to specialists and junior researchers in the domain of propulsion and power, as well as those whose work involves various applications related to atmospheric, oceanic and planetary physics.

Turbulent Drag Reduction by Surfactant Additives

by Feng-Chen Li Bo Yu Jin-Jia Wei Yasuo Kawaguchi

Turbulent drag reduction by additives has long been a hot research topic. This phenomenon is inherently associated with multifold expertise. Solutions of drag-reducing additives are usually viscoelastic fluids having complicated rheological properties.

Turbulent Heating and Anisotropy in the Solar Wind: A Numerical Study (Springer Theses)

by Victor Montagud-Camps

This book presents two important new findings. First, it demonstrates from first principles that turbulent heating offers an explanation for the non-adiabatic decay of proton temperature in solar wind. Until now, this was only proved with reduced or phenomenological models. Second, the book demonstrates that the two types of anisotropy of turbulent fluctuations that are observed in solar wind at 1AU originate not only from two distinct classes of conditions near the Sun but also from the imbalance in Alfvén wave populations. These anisotropies do not affect the overall turbulent heating if we take into account the relation observed in solar wind between anisotropy and Alfvén wave imbalance. In terms of the methods used to obtain these achievements, the author shows the need to find a very delicate balance between turbulent decay and expansion losses, so as to directly solve the magnetohydrodynamic equations, including the wind expansion effects.

The Turbulent Universe

by Paul Kurtz

In his final book, the late Paul Kurtz outlines his personal vision for a planetary ethics inspired by scientific wisdom. Blending realism and optimism, he lays out the basic principles of an ethical approach that he calls humanist eupraxsophy--that is, the application of practical moral choices inspired by scientific wisdom. Emphasizing the dramatic character of the biosphere, human affairs, and the physical universe itself, Kurtz has structured the book in terms of an operatic scenario, with an overture, intermezzo, nine acts, and a grand finale. Citing the emergence of a new planetary civilization, he proposes the development of a planetary ethics based on universal human rights, free scientific inquiry unfettered by dogma, an attitude of exuberance toward human potentials, and courage and determination in the face of the daunting challenges of our time. Kurtz concludes on an enthusiastic note: there is meaning to be found in creative human endeavors as well as a sense of awe and profound reverence inspired by the spectacle of the enormous universe and the prospects for the human adventure.

Turbulente Strömungen: Einführung in die Physik eines Jahrhundertproblems (essentials)

by Heinz Herwig

Heinz Herwig zeigt, dass turbulente Strömungen in Natur, Technik und im Alltag die Regel sind und nicht etwa die Ausnahme. Nicht zuletzt ist dies einer der Gründe, warum man sich mit der Physik turbulenter Strömungen befassen sollte. Dies geschieht hier anhand theoretischer und praktischer Fragestellungen. Turbulenz ist in diesem essential nicht als eigenständiges Phänomen gemeint, sondern tritt im Zusammenhang mit Strömungen von gasförmigen oder flüssigen Medien auf.

Turing's Cathedral

by George Dyson

"It is possible to invent a single machine which can be used to compute any computable sequence," twenty-four-year-old Alan Turing announced in 1936. In Turing's Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing's vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things--and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson's account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It's no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time. How did code take over the world? In retracing how Alan Turing's one-dimensional model became John von Neumann's two-dimensional implementation, Turing's Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

Turing's Legacy: Developments from Turing's Ideas in Logic

by Rod Downey

Alan Turing was an inspirational figure who is now recognised as a genius of modern mathematics. In addition to leading the Allied forces' code-breaking effort at Bletchley Park in World War II, he proposed the theoretical foundations of modern computing and anticipated developments in areas from information theory to computer chess. His ideas have been extraordinarily influential in modern mathematics and this book traces such developments by bringing together essays by leading experts in logic, artificial intelligence, computability theory and related areas. Together, they give insight into this fascinating man, the development of modern logic, and the history of ideas. The articles within cover a diverse selection of topics, such as the development of formal proof, differing views on the Church–Turing thesis, the development of combinatorial group theory, and Turing's work on randomness which foresaw the ideas of algorithmic randomness that would emerge many years later.

Turkana Boy

by Jean-François Beauchemin Jessica Moore

In this contemplative novel-poem, Jean-François Beauchemin invites us to share in the inner world of the grieving Mr. Bartolomé, who, following the mysterious disappearance of his young son, wanders and wonders, seeking to transcend his pain by encountering something larger than himself. Continuously occupied by the memory of his lost son, Bartolomé's quest leads him from the city to the countryside and then to the edge of the ocean, where he marvels at the beauty of nature but cannot penetrate its mysteries.Through reference to the two-million-year-old "Turkana Boy," the fossilized remains of a boy found in 1984 near Lake Turkana, Kenya, Beauchemin addresses processes of memory and the long history of human evolution. Beauchemin's character Bartolomé sees in the lives of the boys-separated by nearly two million years-a kind of twin destiny. Has the passage of millennia changed the intensity of human feeling at the loss of blood relations? "Who knows what they had felt? Had the same emotions, those associated with incommensurable loss, broken their bodies, as they had his? Over and above morphological differences sculpted by the passage of millennia, was there something resembling a permanence of feeling, a sort of eternity for the murmuring of the heart, transmitted through the ages by the bonds of blood?"Turkana Boy offers a poignant examination of grieving and one man's search for understanding. This surrealist narrative is punctuated with magnificent musings on the world and startling questions about what it means to be alive.

Turkey's Nuclear Future

by Sinan Ülgen George Perkovich

Turkey, with a robust modern economy and growing energy needs, is pursuing a switch to nuclear power. But that shift is occurring in an environment fraught with security challenges: Turkey borders Iraq, Syria, and Iran-all states with nuclear or WMD ambitions or capabilities. As a NATO member, Turkey also hosts U.S. nuclear bombs on its territory, although some question the durability of this relationship. This dynamic has naturally led to speculation that Turkish leaders might someday consider moving beyond a civilian course to develop nuclear weapons. Yet there has been remarkably little informed analysis and debate on Turkey's nuclear future, either within the country or in broader international society. This volume explores the current status and trajectory of Turkey's nuclear program, adding historical perspective, analytical rigor, and strategic insight.

Turkey's Water Policy: National Frameworks and International Cooperation

by Annika Kramer Waltina Scheumann Aysegul Kibaroglu

Water is a strategic natural resource of vital importance to all nations. As such it has been the cause of several international disputes. For Turkey especially, water is crucial to social and economic development. Turkey's current national water regime that emphasises water resources development and management for productive uses, however, faces growing environmental concerns and international criticism regarding transboundary water cooperation. Furthermore, EU accession requires Turkey to adopt an extensive and ambitious body of EU water law. To understand Turkey's position to international water law, the national policies and socio-economic circumstances that impact water resources management need to be considered. This book fills the existing knowledge gap through a broad perspective and analysis of the current state of Turkey's water policy and its management of both national and transboundary waters. It is a unique undertaking that brings together Turkish and international authors, practitioners and academics, covering all aspects of water management
