Aiaa 2000-0540 Les and Des Investigations of Turbulent Flow over a Sphere

Large Eddy Simulation (LES) and Detached Eddy Simulation (DES) are applied to prediction and investigation of the ow around a sphere. DES is a hybrid approach in which the closure is a simple modi cation to the Spalart-Allmaras model, reducing to Reynolds-Averaged Navier-Stokes (RANS) in attached regions, and LES away from the wall . Calculations are performed at a Reynolds number, Re = 10, in ...

“Burgulence” to appear in Les Houches 2000: New Trends in Turbulence

This is a review of selected work on the one-and multi-dimensional random Burgers equation (burgulence) with emphasis on questions generally asked for incompressible Navier–Stokes turbulence, such as the law of decay of the energy and the pdf of velocity gradients. Most of the material is devoted to decaying (unforced) burgulence. For more details see the Table of Contents.

Physiological Profi les of Elite Wheelchair Basketball Players in Preparation for the 2000 Paralympic Games

The purpose of this study was to examine the physiological changes in elite wheelchair basketball players leading up to the 2000 Paralympics. Twelve male players attended regular physiological assessments on six occasions; averaged data of two sessions for each year were used. Physiological measures included body mass, skinfold measurements, peak oxygen uptake and peak power obtained during max...

Les Rotations Et Les Quaternions

La construction du corps non commutatif H de quaternions est une variante plus compliquée de la construction du corps commutatif C de nombres complexes. Donc on commence en rappelant la construction de C à partir de R. Les nombres complexes s’écrivent a+ bi avec a, b ∈ R. Donc C est un espace vectoriel sur R de dimension 2 avec base {1, i}. La loi d’addition de C est celle que C possède en tant...
