    Description / Table of Contents: Sommario Nel presente lavoro viene presentato uno studio riguardante le proprietà della cosiddetta funzione di forma $$f\left( {\frac{r}{\eta }} \right)$$ che caratterizza le leggi di scala delle fluttuazioni di velocità in un flusso turbolento. L'analisi é basata su precedenti misure sperimentali effettuate in flussi turbolenti generati da griglie a bassi Reλ ed in condizioni omogenee e non omogenee. Le proprietá di universalitá della funzione di forma sono studiate nell'ambito della cosiddetta Extended Self-Similarity.
    Notes: Abstract In this work some investigations on the properties of the so calledform function $$f\left( {\frac{r}{\eta }} \right)$$ which characterizes the scaling behavior of the small scales fluctuations in a turbulent flow are presented. The present analysis is based on previous experimental measurements in homogeneous and non-homogeneous grid-generated turbulence at low Reλ. The universality properties of the form function are investigated in the frame of the Extended Self Similarity (ESS) form of scaling.
