 ">The phenomenology of fluid turbulence\, and its stochastic representatio
 n</a>\nby Laurent Chevillard (Laboratoire de physique\, CNRS et ENS de Lyo
 n) as part of Séminaire de physique mathématique IPhT\n\nLecture held in
  Salle Claude Itzykson\, Bât. 774\, Orme des Merisiers.\n\nAbstract\nI wi
 ll begin with presenting and illustrating the standard phenomenology of th
 ree-dimensional (statistically) isotropic and homogeneous fluid turbulence
 \, which is mainly attributed to Kolmogorov. Then\, while designing random
  fields able to reproduce/model the implied intricate spatial structure of
  kinematic quantities of interest\, and some crucial mechanisms of the Nav
 ier-Stokes equations\, I will explain how come the celebrated Harish-Chand
 ra--Itzykson--Zuber integral over the orthogonal group enters in a probabi
 listic picture of such a phenomenology. This aspect has been developed wit
 h C. Garban\, R. Pereira\, R. Rhodes\, R. Robert and V. Vargas.\n
