The MacTutor History of Mathematics archive : Claude Louis Marie Henri Navier Born: 10 Feb 1785 in Dijon, France Died: 21 Aug 1836 in Paris, France Claude Navier He worked on applied topics such as engineering, elasticity and fluid mechanics. He made contributions to Fourier series and their application. He gave the well known Navier-Stokes equations for an incompressible fluid in 1821. In 1822 he gave equations for viscous fluids. A specialist in road and bridge building, he was the first to develop a theory of suspension bridges which before then had been built to empirical principles.

Technological change cannot be described only as a succession of controversies and minute adaptations, of the kind that the sociology of knowledge takes most of the time into account. Technological change is also the result of global displacements that one can best interpret with the help of the notion of technological system. Historians have proposed various definitions of this notion. But two definitions seem to me especially significant. They are at once complementary in their approach to technological regulations and to technological change seen as system shift. The French historian Bertrand Gille gave the first of my two definitions in a general survey of the history of technology. Struck by the fact "that within some limits, as a very general rule, all techniques are, to various degrees, depending on one another, so that there should be some coherence between them

CWI fact sheet PDF version UNDERSTANDING FLOWS BY MEANS OF THE COMPUTER When stirring milk in your coffee you usually won't realize that scientifically it is still not quite clear how these two fluids mix together. Flow problems, as in this common example, arise in many industrial settings, e.g., water flow around ship hulls and air flow around airplane wings. Insight into these problems has increased considerably during the last decades, due to the computer in particular. However, many (fundamental) questions remain unsolved. The study of fluid and gas flows by means of the computer (CFD - Computational Fluid Dynamics) is a major research theme at CWI for years. One challenge in the hydrodynamic design of ships is to find the optimal shape of the ship hull satisfying prior requirements of use, economy, safety, etc. Left: Old ship hull. The long waves made by the ship have a high amplitude and, hence, a high energy (provided by the ship). Right: Improved ship hull. Due to CFD the height of the long waves could be strongly reduced.

Marco Cannone Navier : explosion et chute Résumé : This talk is divided into two parts. The first is an historical introduction to Claude Navier as an Engineer at the Ecole des Ponts et Chaussees. At the same time as publishing his famous fluid equations (in 1821), Navier designed the first monumental suspension bridge to be built in Paris over the Seine. His bridge developed a crack (in fact it collapsed !) just before it was to open and political battles resulted in the removal of the bridge. Accusations were made that Navier was too ``much of a theoretical mathematician" and not ``practical''like the British bridge builders such as Brunel or Stevenson. This debate was a version of a more general dispute between the French and British approaches to mathematics, physics and engineering. The second part of talk is devoted to the mathematical concept of ``blow-up'' for the Navier-Stokes equations. This concept has received considerable publicity recently in the context of one of ``the million dollar'' prize problems offered by the Clay Mathematical Institute. Briefly stated, an important problem in fluid dynamics is to answer to the following question: in three dimensions, does the velocity field of a fluid flow that starts smooth remain smooth for all time, as the field evolves under the Navier-Stokes equations ? If a physical quantity such as the velocity, satisfying realistic boundary conditions, could develop a singularity in finite time, the phenomenon is referred to as ``blow-up''. We will review some mathematical challenging problems related to the concept of ``blow-up'' for the Navier-Stokes equations.

Editorial Staff quick search Search Physics World Physics World December 1999 Turbulence nears a final answer Physics in Action: December 1999 The great Italian scientist Leonardo da Vinci was the first person to use the word "turbulence" (or turbolenza) to describe the complex motion of water or air. By carefully examining the turbulent wakes created behind obstacles placed in the path of a fluid, he found that there are three key stages to turbulent flow. Turbulence is first generated near an obstacle. Long-lived "eddies" - beautiful whirls of fluid - are then formed. Finally, the turbulence rapidly decays away once it has spread far beyond the obstacle. However, it was not until the early 19th century that Claude Navier was able to write the basic equations governing how the velocity of a turbulent fluid evolves with time. Navier realized that the earlier equations of Leonhard Euler for ideal flow had to be supplemented by a diffusion term that took into account the viscosity of the fluid. Modelling turbulent transport thus became - and remains to this day - a major challenge.

Grand Challenge Equations We call the equations shown below the grand challenge equations because they are a broad selection of the expressions that relate fundamental quantities in the various computational sciences. Newton's equation is the fundamental equation of classical mechanics, relating the force acting on a body to the change in its momentum over time. Computational scientists and engineers use it in all calculations involving moving bodies, from civil engineering to astrophysics. (Sir Isaac Newton, 1642-1727.) The is the basic equation of quantum mechanics. In time-dependent form, it describes the evolution of atomic-scale motions and is widely used by chemists studying the dynamics of chemical reactions. The Navier-Stokes equation is the primary equation of computational fluid dynamics, relating pressure and external forces acting on a fluid to the response of the fluid flow. Forms of this equation are used in computations for aircraft and ship design, weather prediction, and climate modeling. (Claude Louis Marie Navier, 1785-1836; Sir George Gabriel Stokes, 1819-1903.)

Lagrange's algebraisation of the calculus was meant to improve the rigour of the subject; but his case was unproven, especially his reliance on Taylor series. It was also somewhat purish for the needs of future engineers, whose understanding was apparently further handicapped by his poor lecturing style. He was succeeded in 1799 by Lacroix, who emphasised Lagrange's version in his huge three-volume Trait© de calcul diff©rentiel et int©gral (1797-1800). By contrast, in his shorter Trait© ©l©mentaire (first edition 1802), based upon his teaching at the school, he showed some preference for limits, which had received only a modest measure of support in eighteenth-century France due largely to the praise of J. le R. d'Alembert (1717-1783). Isaac Newton's version using fluxions and fluents was little used on the Continent.

Home Headlines Understanding the equations key to taming turbulence Fabian Waleffe 37K JPG "The weather is very large-scale turbulence. That's why it's so hard to predict," says Professor Fabian Waleffe Almost every flow we know is turbulent, he says, citing not only the weather, but other common examples such as blood flow, boiling water, air rushing around a moving vehicle, and oil traveling through a pipeline. But while turbulence is ubiquitous, it is not well understood, despite studies that began as early as the 1500s, with artist Leonardo da Vinci's observations of and drawings of water flows. Then in the 1880s, scientists Claude-Louis Navier and George Stokes derived the equations that govern fluid flow and describe it well, but which are tremendously complicated to solve, even with the help of a supercomputer. "We're not able to derive from the equations when turbulence occurs, or what is turbulence, or how to describe it," says Waleffe. As a result, engineers must resort to ad hoc empirical formulas of limited validity and scientists must study turbulence at its most basic, or slowest-moving, level. "Even if you just walk around, we cannot fully calculate the air flow around you," he says. He is using the Navier-Stokes equations to calculate solutions that describe the turbulent structures scientists have long observed in channel flows and boundary layers.
