Abstract

The analysis of velocity fluctuations in the interplanetary space plasma reveals the existence of anomalous scaling exponents for the high-order velocity structure function. In this paper we analyze two examples coming from measurements of the fluctuations by both the Helios and the Voyager satellite. We show that the scaling exponents can be fitted by the existing intermittency models and, by introducing the singularity spectra D(h), we show that the turbulence has a multifractal structure.
