Abstract
In this letter we present numerical and experimental results on the scaling properties of velocity turbulent fields in the range of scales where viscous effects are acting. A generalized version of extended self-similarity capable of describing scaling laws of the velocity structure functions down to the smallest resolvable scales is introduced. Our findings suggest the absence of any sharp viscous cut-off in the intermittent transfer of energy. © 1995 IOP Publishing Ltd.File in questo prodotto:
