Dependence of Levy Statistics With Reynolds Number Application to turbulence intermittency and spray modeling
Conference paper
Abstract
In this poster, we show that Kida's log-stable law for the intermittency of turbulence can be extended over a wide Range of Taylor scale Reynolds number Re »elds a simple relation between the scale parameter of the law and Re » log-normal laws were firstly introduced by Kolmogorov for the size of particles under pulverization, log-stable laws are applied to the experimental drop size p.d.f in an annular gas-liquid flow. Though the fitting is quite good there does not seem to be any clear relationship between the parameters of the law and the external parameters of the experiment. This may be related to a breaking of the homogeneity hypothesis.
