Kappa Distributions and Isotropic Turbulence

Kappa Distributions and Isotropic Turbulence

In this work, the two-point probability density function (PDF) for the velocity field of isotropic turbulence is modeled using the kappa distribution and the concept of superstatistics. The PDF consists of a symmetric and an anti-symmetric part, whose symmetry properties follow from the reflection s...
