An Aspect of Granulence in View of Multifractal Analysis

Abstract

The probability density function of velocity fluctuations of glanulence observed by Radjai and Roux in their two-dimensional simulation of a slow granular flow under homogeneous quasistatic shearing is studied by the multifractal analysis for fluid turbulence proposed by the present authors. It is shown that the system of granulence and of turbulence have indeed common scaling characteristics.
