Seu principal trabalho, publicado em 1822, s£o as equa§µes de movimento dos fluidos, que descrevem matematicamente o movimento de qualquer l­quido ou g¡s, como a ¡gua e o ar atmosf©rico. Na verdade, a teoria j¡ existia, mas Navier acrescentou a viscosidade nas equa§µes, colocando-as em bases matem¡ticas s³lidas. Podemos entender a viscosidade, de l­quidos ou de gases, pelos sintomas que ela nos provoca. Quando colocamos a m£o na correnteza de um rio ou no vento, sentimos que ela © carregada pelo fluxo. Se n£o existisse viscosidade, sentir­amos a correnteza ou o vento, mas nossa m£o n£o seria levada por eles. Intuitivamente, podemos perceber que o mel © mais viscoso que a ¡gua, por exemplo.

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.

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.

As yet, however, no one has been able to prove the uniqueness of the solution of Navier-Stokes equations, considered one of the seven greatest unsolved mathematical puzzles both because of difficulty and central importance to modern mathematics.

Studier i et badekar Tomas Bohr har flyttet sit forskningsfelt fra køkkenvasken til badekarret. Han har en doktorgrad i turbulente dynamiske systemer og siger, at han stadig ikke forstår fænomenet turbulens til bunds. Turbulens Af Michael Cramer Andersen Hvordan beskriver man en væske matematisk? Det er relativt let at skrive ligningen ned, men det er straks sværere at løse dem. Ligesom væsken selv, har løsningerne og ligningen det med at glide ud mellem fingrene på én. Ligningerne hedder »Navier-Stokes ligningerne«, og har været kendt i 150 år. »Det er en fænomenologisk ligning, som giver en makroskopisk beskrivelse af alle bevægelser væske«, siger Tomas Bohr, der kender Navier-Stokes ligningerne fra både teoretiske og praktiske studier. Tomas Bohr, der er barnebarn af Niels Bohr, blev doktor på Niels Bohr Institutet i 1996 på en afhandling om »Turbulent Dynamical Systems«. Han har de sidste 13 år beskæftiget sig med forskellige aspekter af turbulensfænomener og væskestrømninger og er nu professor ved Fysisk Institut på Danmarks Tekniske Universitet, hvor hans to fætre Henrik og Jakob Bohr i øvrigt også forsker.

web hosting domain names email addresses Turbulent times for fluids Babbling brooks and bracing breezes may please poets but they bother physicists. These natural examples of turbulence are difficult to analyse mathematically. Now, theories of chaos combined with some simple laboratory experiments may provide some answers. Tom Mullin TURBULENCE is probably the most important and yet least understood problem in classical physics. The majority of fluid flows that are interesting from a practical point of view-from the movement of air in the atmosphere to the flow of water in central heating systems-behave in a disordered way. Turbulence has always worried physicists because it is so difficult to model. In 1932, the British physicist, Horace Lamb, told a meeting of the British Association for the Advancement of Science: "I am an old man now, and when I die and go to Heaven there are two matters on which I hope for enlightenment. One is quantum electrodynamics, and the other is the turbulent motion of fluids. And about the former I am really rather optimistic." (A)When the tap is only slightly open, waterfalls in a streamlined way. Even so, calulating what is happening is extremely difficult. (B)Turning the tap further causes the water to flow turbulently. It is virtually impossible to describe this state of affairs as a mathematical equation.

Navier (1785-1836) added viscous forces and rederived an improved set of equations then called the Navier equations. The latter equations were rederived by Simeon-Denis Poisson in 1831 and George Gabriel Stokes (1819-1903) in 1849. These equations, which are now called the Navier-Stokes equations, are widely used in various fluid dynamical applications, such as computing the flows around turbine and compressor blades, helicopter rotors, airplanes and missiles. Specific applications include its use by the National Aeronautics and Space Administration (NASA) uses it to collect data that complement those obtained from wind tunnel experiments and to compute the flow field around a B-747 carrier aircraft transporting the Space Shuttle Orbiter; by United Technologies Research Center to compute the multicomponent flowfield patterns inside a centrifugal compressor.
