Saint-Venant Jean claude SaintVenant was a student at the Ecole Polytechnique, entering the in1843 in which he gave the correct derivation of the navier-Stokes equations. http://www.fmi.uni-sofia.bg/fmi/contmech/kmarkov/history/Saint-Venant.html
Extractions: Died: 6 Jan 1886 in St Ouen, Loir-et-Cher, France Jean Claude Saint-Venant Liouville Coriolis Saint-Venant worked mainly on mechanics, elasticity, hydrostatics and hydrodynamics. Perhaps his most remarkable work was that which he published in 1843 in which he gave the correct derivation of the Navier Stokes equations. Anderson writes in [2]:- Seven years after Navier 's death, Saint-Venant re-derived Navier 's equations for a viscous flow, considering the internal viscous stresses, and eschewing completely Navier 's molecular approach. That paper was the first to properly identify the coefficient of viscosity and its role as a multiplying factor for the velocity gradients in the flow. He further identified those products as viscous stresses acting within the fluid because of friction. Saint-Venant got it right and recorded it. Why his name never became associated with those equations is a mystery. certainly it is a miscarriage of technical attribution. We should remark that Stokes , like Saint-Venant, correctly derived the Navier Stokes equations but he published the results two years after Saint-Venant.

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."

Extractions: control it. by Parviz Moin and John Kim We all pass through life surroundedand even sustainedby the flow of fluids. Blood moves through the vessels in our bodies, and air (a fluid, properly speaking) flows into our lungs. Our vehicles move through our planet's blanket of air or across its lakes and seas, powered by still other fluids, such as fuel and oxidizer, that mix in the combustion chambers of engines. Indeed, many of the environmental or energy-related issues we face today cannot possibly be confronted without detailed knowledge of the mechanics of fluids. Practically all the fluid flows that interest scientists and engineers are turbulent ones; turbulence is the rule, not the exception, in fluid dynamics. A solid grasp of turbulence, for example, can allow engineers to reduce the aerodynamic drag on an automobile or a

Extractions: December 6 - 14, 1997 The proceedings of the conference already appeared. It is supposed that every lecturer will give five one-hour-long comprehensive lectures and lead two seminars focused on the interaction between the lecturer and the audience. The participants can present their results in the framework of short communications and/or they can exhibit their papers and preprints (the number of papers/preprints is not limited, they may be related to other scientific area than fluid mechanics; the idea is that there will be an exhibition place located within the hotel, on which the papers and preprints will be exhibited during the whole school). Claude BARDOS (ENS de Cachan, Centre de Mathematiques et leurs Applications, Cachan, France): The Boltzman equation as a link between microscopic and macroscopic description of fluids motions The Boltzmann or more generally the kinetic equations play an important role in the understanding of the coherence of the laws of physic from a microscopic description (at the level of particles) to a macroscopic description using the Navier-Stokes or Euler equations. These relations are also useful for many applications involving rarefied gases of particles, for instance the problem of reentry of a space vehicle in the atmosphere, or the behaviour of the electric current in a microscopic semi-conductor as used in modern computers.

Extractions: In honor of Claude Bardos This workshop is dedicated to results and open problems in the field of "hydrodynamic limits" in a broad sense, both for classical and quantum mechanical systems. Some recent results on Hilbert's Sixth Problem on the limit from the Boltzmann equation to Navier-Stokes and similar macroscopic "fluid equations" are presented. The event is the second part of a "twin colloquium" in honour of Claude Bardos who is one of the key figures in this field. The first part took place in Paris, at the IHP (Institute Henri Poincare) in the course of a thematically close special trimester organized by F. Golse.

Extractions: We consider the laminar viscous incompressible flow over a boundary containing surface irregularities. Such surfaces cause boundary layers for the velocity gradient and the pressure field, and solving numerically the Navier-Stokes equations requires very fine grids. In engineering practice, the grooved boundary effects are reduced to a coefficient in the effective interface law, posed on a smooth surface. These upscaled laws are called the wall laws and are of importance in applications. In this talk we suppose the periodic irregularities of the same characteristic length and height. Characteristic size of the imperfections is small and we study the asymptotic behavior of the solution for the incompressible Navier-Stokes equation, when it tends to zero. After constructing appropriate boundary layers, we obtain the Navier slip condition as the corresponding wall law. We justify it for moderate Reynolds numbers by estimating the difference between the physical solution and the upscaled solution in appropriate norms. The norm of the difference behaves as a power of the characteristic roughness. The effective coefficient in the Navier's law is determined through an auxiliary boundary layer. Finally, we show that presence of the irregularities (riblets) diminishes the tangential drag force.
