Some Aspects of Turbulent Relative Particle Dispersion

In this paper, several aspects of the turbulent relative particle dispersion are considered, many of which are motivated by laboratory experiment and numerical simulation results. These are, * spatial intermittency effects, (a) reduction of relative particle dispersion in 3D; (b) prevalence of power-law scaling of relative particle dispersion in 2D enstrophy cascade; * quasi-geostrophic aspects exhibiting an enhanced relative particle dispersion in the baroclinic regime and a negative eddy-viscosity development for some insight into this aspect; * reduction of relative particle dispersion and prevalence of the ballistic regime due to compressibility effects.
