Analisi SO(3) delle leggi di scala in un flusso di shear omogeneo.

We present the SO(3) decomposition for the longitudinal structure funcions in a homogeneous shear flow by using high Reynolds number experimental and numerical data. We show how scaling laws differ from the isotropic case due to the mechanism of turbulent kinetic energy production while eventual anisotropic contaminations are excluded. Finally scaling laws in the anisotropic sectors are addressed. Here scaling exponents are shown to be dependent both on the sector and on the projection index, respectively.
