This is a graduate text on turbulent flows, an important topic in fluid dynamics. It is up-to-date, comprehensive, designed for teaching, and is based on a course taught by the author at Cornell University for a number of years. The book consists of two parts followed by a number of appendices. Part I provides a general introduction to turbulent flows, how they behave, how they can be described quantitatively, and the fundamental physical processes involved. Part II is concerned with different approaches for modelling or simulating turbulent flows. The necessary mathematical techniques are presented in the appendices. This book is primarily intended as a graduate level text in turbulent flows for engineering students, but it may also be valuable to students in applied mathematics, physics, oceanography and atmospheric sciences, as well as researchers and practising engineers.
In an instant everything stops. No lights. No phones. No transportation. How would you get home?When coordinated EMP and Cyber attacks wipe out the nation's power grid, communications and transportation systems, ultra marathon runner, Maddie Langston is forced to run for her life. Stranded in a Chicago airport when the lights go out, Maddie is in a race against time. According to her father, she doesn't have long before the city descends into chaos. She must leave the airport before it is too late. Although she knows she must flee the Windy City, Maddie's first battle is to overcome fear of the violence she knows is coming. She's a fighter; she just doesn't know it yet. The perilous journey out of the city becomes even more difficult when Maddie takes responsibility for an orphaned ten-year-old girl. Together, they must fight to survive as chaos fills the streets and and struggle to survive in a Turbulent new world.Would you have what it takes to survive?This heart-stopping post-apocalyptic thriller is the first book in T.

Advanced Approaches in Turbulence: Theory, Modeling, Simulation and Data Analysis for Turbulent Flows focuses on the updated theory, simulation and data analysis of turbulence dealing mainly with turbulence modeling instead of the physics of turbulence. Beginning with the basics of turbulence, the book discusses closure modeling, direct simulation, large eddy simulation and hybrid simulation. The book also covers the entire spectrum of turbulence models for both single-phase and multi-phase flows, as well as turbulence in compressible flow. Turbulence modeling is very extensive and continuously updated with new achievements and improvements of the models. Modern advances in computer speed offer the potential for elaborate numerical analysis of turbulent fluid flow while advances in instrumentation are creating large amounts of data. This book covers these topics in great detail. - Covers the fundamentals of turbulence updated with recent developments - Focuses on hybrid methods such as DES and wall-modeled LES - Gives an updated treatment of numerical simulation and data analysis
In recent years, turbulence has become a very lively area of scientific research and application, attracting many newcomers who need a basic introduction to the subject. Turbulent Flows ably meets this need, developing both physical insight and the mathematical framework needed to express the theory. The authors present basic theory and illustrate it with examples of simple turbulent flows and classical models of jets, wakes, and boundary layers. A deeper understanding of turbulence dynamics is provided by their treatment of spectral analysis and its applications.
Managing in Turbulent Times tackles the key issues facing managers in the 1990s: how to manage in rapidly changing environments. This seminal and prophetic book laid the foundation for a generation of writers on change management. This book concerns the immediate future of business, society and the economy. The one certainty about the times ahead, says Drucker, is that they will be turbulent times. In turbulent times the first task of management is to make sure of the organizations capacity for survival, to make sure of its structural strength and soundness, its capacity to survive a blow, to adapt to sudden change and to avail itself of new opportunities. The author is concerned with action rather than understanding, with decisions rather than analysis. It aims at being a practical book for the decision maker, whether in the private or the public sector.
obtained are still severely limited to low Reynolds numbers (about only one decade better than direct numerical simulations), and the interpretation of such calculations for complex, curved geometries is still unclear. It is evident that a lot of work (and a very significant increase in available computing power) is required before such methods can be adopted in daily's engineering practice. I hope to l"Cport on all these topics in a near future. The book is divided into six chapters, each· chapter in subchapters, sections and subsections. The first part is introduced by Chapter 1 which summarizes the equations of fluid mechanies, it is developed in C~apters 2 to 4 devoted to the construction of turbulence models. What has been called "engineering methods" is considered in Chapter 2 where the Reynolds averaged equations al"C established and the closure problem studied (§1-3). A first detailed study of homogeneous turbulent flows follows (§4). It includes a review of available experimental data and their modeling. The eddy viscosity concept is analyzed in §5 with the l"Csulting ~alar-transport equation models such as the famous K-e model. Reynolds stl"Css models (Chapter 4) require a preliminary consideration of two-point turbulence concepts which are developed in Chapter 3 devoted to homogeneous turbulence. We review the two-point moments of velocity fields and their spectral transforms (§ 1), their general dynamics (§2) with the particular case of homogeneous, isotropie turbulence (§3) whel"C the so-called Kolmogorov's assumptions are discussed at length.

"A broad panorama in brilliant prose." --American Historical Review In this groundbreaking work of labor history, Irving Bernstein uncovers a period when industrial trade unionism, working-class power, and socialism became the rallying cry for millions of workers in the fields, mills, mines, and factories of America. With an introduction by Frances Fox Piven.
Most natural and industrial flows are turbulent. The atmosphere and oceans, automobile and aircraft engines, all provide examples of this ubiquitous phenomenon. In recent years, turbulence has become a very lively area of scientific research and application, attracting many newcomers who need a basic introduction to the subject. An Introduction to Turbulent Flow, first published in 2000, offers a solid grounding in the subject of turbulence, developing both physical insight and the mathematical framework needed to express the theory. It begins with a review of the physical nature of turbulence, statistical tools, and space and time scales of turbulence. Basic theory is presented next, illustrated by examples of simple turbulent flows and developed through classical models of jets, wakes, and boundary layers. A deeper understanding of turbulence dynamics is provided by spectral analysis and its applications. The final chapter introduces the numerical simulation of turbulent flows. This well-balanced text will interest graduate students in engineering, applied mathematics, and the physical sciences.
"Stimulating, incisive, insightful, sometimes revisionist, this volume is required reading for historians of comparative colonialism in an age of revolution." —Choice "[An] eminently original and intellectually exciting book." —William and Mary Quarterly This volume examines several slave societies in the Greater Caribbean to illustrate the pervasive and multi-layered impact of the revolutionary age on the region. Built precariously on the exploitation of slave labor, organized according to the doctrine of racial discrimination, the plantation colonies were particularly vulnerable to the message of the French Revolution, which proved all the more potent because it coincided with the emergence of the antislavery movement in the Atlantic world and interacted with local traditions of resistance among the region's slaves, free coloreds, and white colonists.
