Forward and backward multi-particle dispersion in homogeneous isotropic turbulence

Forward and backward multi-particle dispersion in homogeneous isotropic turbulence

Turbulent diffusion in homogeneous isotropic turbulence is numerically investigated using the direct numerical simulation (DNS). The four-dimensional turbulence database allows us to track fluid particles not only in the forward direction of time but also in the backward direction. Two-particle disp...
