Sur la fermeture des termes rapides pour des écoulements moyens rotationnels

The modelling of homogeneous turbulent flows with mean rotatio, considered in a previous Note, is handled under the form $\text{M}{}^1\text{=}\text{M}\text{b}\text{,}\text{y}\text{,}\text{Q}{}^1\text{]}$ in terms of componental and dimensional anisotropies, and of the symmetrized stropholysis. A systematic technique of expansion is proposed. The necessary realisability conditions are then applied. It is shown that there exists no realisable functional $\text{M}$ which would be isotropic with respect to its arguments. To cite this article: J. Piquet, C. R. Mecanique 331 (2003).
